The AD7524 is a low cost, 8-bit monolithic CMOS DAC designed for the direct interface to most microprocessors.Basically an 8-bit DAC with input latches. the AD7524's load cycle is similar to the "write" cycle of a random access memory. Using an advanced thin-film on CMOS fabrication process, the AD7524 provides accuracy to 1/8LSB with a typical power dissipation of less than 10 milliwatts.A newly improved design eliminates the protection Schottky previously required and guarantees TTL compatibility when using a +5 supply. Loading speed has been increased for compatibility with most microprocessors.Featuring operation from +5V to +15V, the AD7524 interfaces directly to most microprocessor buses or output ports.Excellent multiplying characteristics (2- or 4-quadrant) make the AD7524 an ideal choice for many microprocessor controlled gain setting and signal control applications.APPLICATIONSMicroprocessor Controlled Gain CircuitsMicroprocessor Controlled Attenuator CircuitsMicroprocessor Controlled Function GenerationPrecision AGC CircuitsBus Structured Instruments

The AD7528 is a monolithic dual 8-bit digital/analog converter featuring excellent DAC-to-DAC matching. It is available in skinny 0.3" wide 20-pin DIP's and in 20-terminal surface mount packages.Separate on-chip latches are provided for each DAC to allow easy microprocessor interface.Data is transferred into either of the two DAC data latches via a common 8-bit TTL/CMOS compatible input port. Control inputDAC A/DAC B determines which DAC is to be loaded. The AD7528's load cycle is similar to the write cycle of a random access memory and the device is bus compatible with most 8-bit microprocessors, including 6800, 8080, 8085, Z80.The device operates from a +5V to +15V power supply, dissipating only 20mW of power.Both DAC's offer excellent four quadrant multiplication characteristics with a separate reference input and feedback resistor for each DAC.PRODUCT HIGHLIGHTSDAC-to-DAC matching: since both of the AD7528 DACs are fabricated at the same time on the same chip, precise matching and tracking between DAC A and DAC B is inherent. The AD7528’s matched CMOS DACs make a whole new range of applications circuits possible, particularly in the audio, graphics and process control areas.Small package size: combining the inputs to the on-chip DAC latches into a common data bus and adding aDAC A/DAC B select line has allowed the AD7528 to be packaged in either a small 20-lead DIP, SOIC or PLCC.APPLICATIONSDigital Control of:Gain/AttenuationFilter ParametersStereo Audio CircuitsX-Y Graphics

The AD7545 is a monolithic 12-bit CMOS multiplying DAC with onboard data latches. It is loaded by a single 12-bit wide word and directly interfaces to most 12- and 16-bit bus systems. Data is loaded into the input latches under the control of theCSandWRinputs; tying these control inputs low makes the input latches transparent, allowing direct unbuffered operation of the DAC.The AD7545 is particularly suitable for single supply operation and applications with wide temperature variations.The AD7545 can be used with any supply voltage from +5 V to +15 V. With CMOS logic levels at the inputs the device dissipates less than 0.5 mW for VDD= +5 V.

The MUX-08 is a monolithic eight-channel analog multiplexer which connects a single output to one of the eight analog inputs depending upon the state of a 3-bit binary address.The MUX-24 is a monolithic four-channel differential analog multiplexer configured in a double pole, four position (plus OFF) electronic switch array. A two-bit binary input address connects a pair of independent analog inputs from each four channel input section to the corresponding pair of independent analog outputs.All switches in the MUX-08/MUX-24 are turned OFF by applying logic "0" to the ENABLE pin, thereby providing a package select function.Fabricated with Precision Monolithics' high performance Bipolar-JFET technology, these devices offer low, constant "ON" resistance, low leakage currents and fast settling time with low crosstalk to satisfy a wide variety of applications.These multiplexors do not suffer from latch-up or static charge blow-out problems associated with similar CMOS parts. The digital inputs are designed to operate form both TTL and CMOS levels while always providing a definite break-before-make action without the need for external pull-up resistors over the full operating temperature range.

The OP77 significantly advances the state-of-the-art in precision op amps. The outstanding gain of 10,000,000 or more for the OP77 is maintained over the full 10 V output range. This exceptional gain-linearity eliminates incorrectable system nonlinearities common in previous monolithic op amps and provides superior performance in high closed-loop gain applications. Low initial VOSdrift and rapid stabilization time, combined with only 50 mW of power consumption, are significant improvements over previous designs. These characteristics, plus the exceptional TCVOSof 0.3 μV/°C maximum and the low VOSof 25 μV maximum, eliminates the need for VOSadjustment and increases system accuracy over temperature.PSRR of 3µV/V (110dB) and CMRR of 1.0µV/V maximum virtually eliminates errors caused by power supply drifts and common-mode signals. This combination of outstanding characteristics makes the OP77 ideally suited for high-resolution instrumentation and other tight error budget systems.

The OP400 is the first monolithic quad operational amplifier that features OP77-type performance. Precision performance is not sacrificed with the OP400 to obtain the space and cost savings offered by quad amplifiers.The OP400 features an extremely low input offset voltage of less than 150 μV with a drift of less than 1.2 μV/°C, guaranteed over the full military temperature range. Open-loop gain of the OP400 is more than 5 million into a 10 kΩ load, input bias current is less than 3 nA, CMR is more than 120 dB, and PSRR is less than 1.8 μV/V. On-chip Zener zap trimming is used to achieve the low input offset voltage of the OP400 and eliminates the need for offset nulling. The OP400 conforms to the industrystandard quad pinout, which does not have null terminals.The OP400 features low power consumption, drawing less than 725 μA per amplifier. The total current drawn by this quad amplifier is less than that of a single OP07, yet the OP400 offers significant improvements over this industry-standard op amp. Voltage noise density of the OP400 is a low 11 nV/√Hz at 10 Hz, half that of most competitive devices.The OP400 is an ideal choice for applications requiring multiple precision operational amplifiers and where low power consumption is critical.

The AD558 DACPORT®is a complete voltage-output 8-bit digital-to-analog converter, including output amplifier, full microprocessor interface and precision voltage reference on a single monolithic chip. No external components or trims are required to interface, with full accuracy, an 8-bit data bus to an analog system.The performance and versatility of the DACPORT is a result of several recently-developed monolithic bipolar technologies. The complete microprocessor interface and control logic is implemented with integrated injection logic (I2L), an extremely dense and low power logic structure that is process-compatible with linear bipolar fabrication. The internal precision voltage reference is the patented low voltage bandgap circuit which permits full-accuracy performance on a single +5 V to +15 V power supply. Thin-film silicon-chromium resistors provide the stability required for guaranteed monotonic operation over the entire operating temperature range (all grades), while recent advances in laser-wafer-trimming of these thin-film resistors permit absolute calibration at the factory to within ±1 LSB; thus no user-trims for gain or offset are required. A new circuit design provides voltage settling to ±1/2 LSB for a full-scale step in 800 ns.The AD558 is available in four performance grades. The AD558J and K are specified for use over the 0°C to +70°C temperature range, while the AD558S and T grades are specified for -55°C to +125°C operation. The "J" and "K" grades are available either in 16-pin plastic (N) or hermetic ceramic (D) DIPS. They are also available in 20-pin JEDEC standard PLCC packages. The "S" and "T" grades are available in the 16-pin hermetic ceramic DIP package.DACPORT is a registered trademark of Analog Devices, Inc.
