FEATURES
q LOW POWER: 200mW q UNIPOLAR OR BIPOLAR OPERATION q SINGLE SUPPLY OUTPUT RANGE: +10V q DUAL SUPPLY OUTPUT RANGE: ±10V q SETTLING TIME: 10µs to 0.003% q 16-BIT MONOTONICITY: 40°C to +85°C q PROGRAMMABLE RESET TO MID-SCALE OR ZERO-SCALE q DOUBLE-BUFFERED DATA INPUTS q ±1 LSB DNL: 40°C to +85°C
DESCRIPTION
The DAC7734 is a 16-bit, quad voltage output, digitalto-analog converter with guaranteed 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 guaranteed specifications over the 40°C to +85°C temperature range.

Exposure to absolute maximum conditions for extended periods may affect device reliability.
ELECTROSTATIC DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Burr-Brown recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
