The MX7545 is a 12-bit CMOS multiplying digital-to-analog converter (DAC) with internal data latches. Input data is loaded as a single 12-bit word and latched under the control of active-low CS and active-low WR inputs. When active-low CS and active-low WR are low, the input data latches are transparent and the DAC output responds to any changes in the digital input. MX7545 works with a single +5V or +15V power supply. Electrical characteristics are specified at both of these supply voltages. With a +5V supply, the digital inputs are +5V TTL and CMOS compatible with high voltage CMOS compatibility is maintained at +15V supply range.Maxim MX7545 uses low tempco thin-film resistors which are laser-trimmed to result in linearity errors that are typically ±¼ LSB and gain errors of maximum ±1 LSB (G grade). The digital inputs are designed with improved protection against electrostatic discharge (ESD) damage and can typically withstand over 6,000V of ESD voltages. The MX7545 is supplied in 20-lead narrow DIP and Small Outline packages.ApplicationsµP-Controlled Calibration CircuitryAutomatic Test EquipmentMotion Control SystemsProgrammable Gain AmplifiersProgrammable Power Supplies

The MX7541A is a high performance CMOS multiplying 12-bit digital-to-analog converter (DAC). Low power operation and 12-bit (0.012%) linearity make it suitable for a wide range of precision data acquisition and control applications. Wafer level laser trimmed thin-film resistors and temperature compensated NMOS switches assure true 12-bit performance over the full operating temperature range. In addition, all digital inputs are compatible with both CMOS and TTL logic levels. Maxim's MX7541A is electrically and pin compatible with Analog Devices AD7541A and AD7541. Package types include 18-lead standard width DIP and Small Outline packages.ApplicationsµP-Controlled Calibration CircuitryAutomatic Test EquipmentDigitally Controlled FiltersMachine and Motion Control SystemsProgrammable Gain AmplifiersProgrammable Power Supplies

The MX7543 is a high precision 12-bit digital-to-analog converter (DAC) which uses a serial rather than parallel input scheme for loading data. Included are a serial-to-parallel shift register, a separate DAC register, and a multiplying DAC. Serial data is clocked in at the SRI pin on the rising or failing edge (user selected) of the strobe input. When the input register is full, the contents are transferred to the DAC register using the load input. A clear input is provided to initialize the part asynchronously. The MX7543 features excellent gain stability (5 ppm/°C max.) and operates from a single +5V power supply while dissipating about 10mW.ApplicationsAuto-Calibration SystemsAutomatic Test EquipmentProgrammable AttenuatorsRemote Analog SystemsRobotics

The Maxim MX7537/MX7547 contain two 12-bit current-output multiplying digital-to-analog converters (DAC) in a single package. Input level shifters, data registers and control logic make microprocessor interfacing straight forward. Operation is from a single +12V to +15V power supply maintaining TTL, 74HC and 5V CMOS logic compatibility. The MX7547 accepts active-low CSA, active-low CSB, active-low WR control signals and 12 data inputs for DAC selection and full parallel data loading. The MX7537 receives data in 2 bytes, using a right justified 8+4 format. A0, A1, active-low CS, active-low WR and UPD signals provide full control for DAC selection and data loading.Each of the DACs in the MX7537/MX7547 provides 4-quadrant multiplication capabilities and separate reference input and feedback resistor pins. The MX7537 additionally makes available separate AGND pins for applications where each DAC is biased at a difference voltage. Since both DACs are on a single monolithic chip, matching and temperature tracking between them is excellent. Gain error is specified at less than ±1 LSB, and 12-bit linearity and monotonicity are guaranteed over the full operating temperature ranges. Maxim's MX7537 and MX7547 are available in narrow 24-lead 0.3" DIP and Wide SO, as well as, 28-pin-lead PLCC packages.ApplicationsAudio Gain ControlAutomatic Test EquipmentDigitally Controlled FiltersMotion Control SystemsProcess ControlSynchro Applications

The MX7548 is a 12-bit CMOS, current output, multiplying digital-to-analog converter (DAC) with a versatile interface for microprocessors using 8-bit busses. The MX7548 accepts data into its input-registers in two bytes in either left- or right-justified format, lease significant byte or most significant byte first. Standard active-low WR and active-low CSLSB or active-low SCMSB inputs control the data load operation. A separate active-low LDAC input controls transfer of data from the input register to the DAC register allowing for simultaneous update of all DACs in multi-DAC systems. A data override input forces the DAC output to full-scale or zero-code without altering the contents of the input registers. This permits the user to perform DAC calibration conveniently without having to load calibration data into the DAC.The MX7548 works with a single +5V, +12V or +15V power supply, and the electrical characteristics are specified at all of these supply voltages. All digital inputs are TTL and +5V-CMOS compatible with any of these supply voltages. Maxim MX7548 uses low tempco thin-film resistors which are laser trimmed to ±¼ LSB linearity and better than ±1 LSB gain accuracy. The digital inputs are designed with improved ESD protection and can typically withstand over 5,000V of ESD voltages. The MX7548 is supplied in 20-lead narrow DIP, PLCC, and Small Outline packages.ApplicationsµP-Controlled SystemsAutomatic Test EquipmentDigitally Controlled FiltersMotion Control SystemsProcess ControlProgrammable Gain AmplifiersProgrammable Power Supplies
