DESCRIPTION
The DAC7664 is a 16-bit, quad voltage output
digital-to-analog converter (DAC) with 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 DAC7664 can operate from a single +5V
supply or from +5V and 5V supplies.
Low power and small size per DAC make the DAC7664
ideal for automatic test equipment, DAC-per-pin
programmers, data acquisition systems, and closed-loop
servo control. The DAC7664 is available in an LQFP-64
package and is specified for operation over the 40
°
C to
+85
°
C temperature range.
This device has ESD-CDM sensitivity and special handling precautions must be taken.
