The DAC7734 is a 16-bit, quad voltage output, digital-toanalog converter (DAC) with ensured 16-bit monotonic performance over the specified temperature range. It accepts 24-bit serial input data, has double-buffered DAC input logic (allowing simultaneous update of all DACs), and provides a serial data output for daisy-chaining multiple DACs. Programmable asynchronous reset clears all registers to a mid-scale code of 8000h or to a zero-scale of 0000h. The DAC7734 can operate from a single +15V supply or from +15V and -15V, and +5V supplies. Low power and small size per DAC make the DAC7734 ideal for automatic test equipment, DAC-per-pin programmers, data acquisition systems, and closed-loop servo-control. The DAC7734 is available in a 48-lead SSOP package and offers ensured specifications over the -40°C to +85°C temperature range.

The DAC7741 is a 16-bit Digital-to-Analog Converter (DAC) which provides 16 bits of monotonic performance over the specified operating temperature range and offers a +10V, low-drift internal reference. Designed for automatic test equipment and industrial process control applications, the DAC7741 output swing can be configured in a ±10V, ±5V, or +10V range. The flexibility of the output configuration allows the DAC7741 to provide both unipolar and bipolar operation by pin strapping. The DAC7741 includes a high-speed output amplifier with a maximum settling time of 5µs to ±0.003% FSR for a 20V full-scale change and only consumes 100mW (typical) of power. The DAC7741 features a standard 16-bit parallel interface with double buffering to allow asynchronous updates of the analog output and data read-back to support data integrity verification prior to an update. A user programmable reset control allows the DAC output to reset to min-scale (0000H) or mid-scale (8000H) overriding the DAC register values. The DAC7741 is available in a LQFP-48 package and three performance grades specified to operate from 0°C to +70°C and -40°C to +85°C.

The DAC7750 and DAC8750 (DACx750) are low-cost, precision, fully-integrated, 12-bit and 16-bit digital-to-analog converters (DACs) designed to meet the requirements of industrial process-control applications. These devices can be programmed as a current output with ranges of 4 mA to 20 mA, 0 mA to 20 mA, or 0 mA to 24 mA. The DACx750 include reliability features such as CRC error checking on the SPI frame, a watchdog timer, an open circuit, compliance voltage, and thermal alarm. In addition, the output current can be monitored by accessing an internal precision resistor. These devices include a power-on-reset function designed to power up the device in a known state (IOUT is disabled and in a Hi-Z state). The CLR pin sets the current output to the low end of the range if the output is enabled. Program the zero and gain registers to digitally calibrate the device in the end system. The output slew rate is also programmable by register. These devices can superimpose an external HART signal on the current output, and operate with a 10-V to 36-V supply.

The DAC7800,DAC7801 and DAC7802 are members of a new family of monolithic dual 12-bit CMOS multiplying Digital-to-Analog Converters (DACs). The digital interface speed and the AC multiplying performance are achieved by using an advanced CMOS process optimized for data conversion circuits. High stability on-chip resistors provide true 12-bit integral and differential linearity over the wide industrial temperature range of –40°C to +85°C. The DAC7800 features a serial interface capable of clocking-in data at a rate of at least 10MHz. Serial data is clocked (edge triggered) MSB first into a 24-bit shift register and then latched into each DAC separately or simultaneously as required by the application. An asynchronous CLEAR control is provided for power-on reset or system calibration functions. It is packaged in a 16-pin 0.3" wide plastic DIP. The DAC7801 has a 2-byte (8 + 4) double-buffered interface. Data is first loaded (level transferred) into the input registers in two steps for each DAC. Then both DACs are updated simultaneously. The DAC7801 features an asynchronous CLEAR control. The DAC7801 is packaged in a 24-pin 0.3" wide plastic DIP. The DAC7802 has a single-buffered 12-bit data word interface. Parallel data is loaded (edge triggered) into the single DAC register for each DAC. The DAC7802 is packaged in a 24-pin 0.3" wide plastic DIP.
