16-Bit, Dual Voltage Output
DIGITAL-TO-ANALOG CONVERTER
DESCRIPTION
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.
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
°
