SBAS233 – DECEMBER 2001

16-Bit, Dual Voltage Output

DIGITAL-TO-ANALOG CONVERTER

DESCRIPTION

FEATURES

ꢀ LOW POWER: 4mW

The DAC7642 and DAC7643 are dual channel, 16-bit, volt-

age output Digital-to-Analog Converters (DACs) which pro-

vide 15-bit monotonic performance over the specified tem-

perature range. They accept 16-bit parallel input data, have

double-buffered DAC input logic (allowing simultaneous up-

date of all DACs), and provide a readback mode of the

internal input registers. Programmable asynchronous reset

clears all registers to a mid-scale code of 8000_H(DAC7642)

or to a zero-scale code of 0000_H(DAC7643). These DACs

can operate from a single +5V supply or from +5V and –5V

supplies, providing an output range of 0 to +2.5V or –2.5V to

+2.5V, respectively.

ꢀ UNIPOLAR OR BIPOLAR OPERATION

ꢀ SETTLING TIME: 10µs to 0.003% FSR

ꢀ 15-BIT LINEARITY AND MONOTONICITY:

–40°C to +85°C

ꢀ RESET TO MID-SCALE (DAC7642) OR

ZERO-SCALE (DAC7643)

ꢀ DATA READBACK

ꢀ DOUBLE-BUFFERED DATA INPUTS

APPLICATIONS

ꢀ PROCESS CONTROL

Low power and small size per DAC make the DAC7642 and

DAC7643 ideal for automatic test equipment, DAC-per-pin

programmers, data acquisition systems, and closed-loop

servo-control. The DAC7642 and DAC7643 are available in

a LQFP-32 package and specified over a –40°C to +85°C

temperature range.
