12-Bit Quad Voltage Output
DIGITAL-TO-ANALOG CONVERTER
FEATURES
DESCRIPTION
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
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.
