DAC7664YR

16位四路电压输出数位类比转换器 16-BIT, QUAD VOLTAGE OUTPUT DIGITAL-TO-ANALOG CONVERTER

DESCRIPON

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.
