16-Bit, Quad Voltage Output
DIGITAL-TO-ANALOG CONVERTER
FEATURES
● LOW POWER: 200mW
DESCRIPTION
The DAC7744 is a 16-bit, quad voltage output digital-
to-analog converter with guaranteed 16-bit monotonic
performance over the specified temperature range. It
accepts 16-bit parallel input data, has double-buffered
DAC input logic (allowing simultaneous update of all
DACs), and provides a readback mode of the internal
input registers. Programmable asynchronous reset
clears all registers to a mid-scale code of 8000H or to
a zero-scale of 0000H. The DAC7744 operates from
either a single +15V supply or from a +15V, –15V,
and +5V supply.
● UNIPOLAR OR BIPOLAR OPERATION
● SINGLE-SUPPLY OUTPUT RANGE: +10V
● DUAL SUPPLY OUTPUT RANGE: ±10V
● SETTLING TIME: 10µs to 0.003%
● 16-BIT MONOTONICITY: –40°C to +85°C
● PROGRAMMABLE RESET TO MID-SCALE
OR ZERO-SCALE
● DATA READBACK
● DOUBLE-BUFFERED DATA INPUTS
Low power and small size per DAC make the DAC7744
ideal for automatic test equipment, DAC-per-pin pro-
grammers, data acquisition systems, and closed-loop
servo-control. The DAC7744 is available in a 48-
lead SSOP package, and offers guaranteed specifica-
tions over the –40°C to +85°C temperature range.
APPLICATIONS
● PROCESS CONTROL
● ATE PIN ELECTRONICS
● CLOSED-LOOP SERVO-CONTROL
