APPLICATIONS
The DAC7654 is a 16-bit, quad voltage output,
digital-to-analog converter (DAC) with 16-bit monotonic
performance over the specified temperature range. It
accepts 24-bit serial input data, has double-buffered DAC
input logic (allowing simultaneous update of all DACs),
and provides a serial data output for daisy-chaining
multiple DACs. Programmable asynchronous reset clears
all registers to a mid-scale code of 8000h or to a zero-scale
of 0000h. The DAC7654 can operate from a single +5V
supply or from +5V and –5V supplies.
Low power and small size per DAC make the DAC7654
ideal for automatic test equipment, DAC-per-pin
programmers, data acquisition systems, and closed-loop
servo-control. The DAC7654 is available in an LQFP
package and is specified for operation over the –40°C to
+85°C temperature range.
