Low Glitch: 1nV-s (typ)  
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: 18mW  
Unipolar or Bipolar Operation  
Settling Time: 12µs to 0.003%  
16-Bit Linearity and Monotonicity:  
–40°C to +85°C  
Programmable Reset to Mid-Scale or  
Zero-Scale

Data Readback  
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.
