12-Bit Quad Voltage Output DIGITAL-TO-ANALOG CONVERTER
FEATURES
q LOW POWER: 250mW max q SINGLE SUPPLY OUTPUT RANGE: +10V q DUAL SUPPLY OUTPUT RANGE: ±10V q SETTLING TIME: 10µs to 0.012% q 12-BIT LINEARITY AND MONOTONICITY: 40°C to +85°C q RESET TO MID-SCALE (DAC7724) OR ZERO-SCALE (DAC7725) q DATA READBACK q DOUBLE-BUFFERED DATA INPUTS
DESCRIPTION
The DAC7724 and DAC7725 are 12-bit quad voltage output digital-to-analog converters with guaranteed 12-bit monotonic performance over the specified temperature range. They accept 12-bit parallel input data, have double-buffered DAC input logic (allowing simultaneous update of all DACs), and provide a readback mode of the internal input registers. An asynchronous reset clears all registers to a mid-scale code of 800H (DAC7724) or to a zero-scale of 000H (DAC7725). The DAC7724 and DAC7725 can operate from a single +15V supply, or from +15V and 15V supplies. Low power and small size per DAC make the DAC7724 and DAC7725 ideal for automatic test equipment, DAC-per-pin programmers, data acquisition systems, and closed-loop servo-control. The DAC7724 and DAC7725 are available in a PLCC-28 or a SO-28 package, and offer 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.
