DAC7725 12 位四路电压输出数模转换器

DAC7725 说明

The DAC7724 and DAC7725 are 12-bit quad voltage output digital-to-analog converters with guaranteed 12-bit monotonic performance over the specified temperature range. They accept 12-bit parallel input data, have double-buffered DAC input logic (allowing simultaneous update of all DACs), and provide a readback mode of the internal input registers. An asynchronous reset clears all registers to a mid-scale code of 800H (DAC7724) or to a zero-scale of 000H (DAC7725). The DAC7724 and DAC7725 can operate from a single +15V supply, or from +15V and –15V supplies.

Low power and small size per DAC make the DAC7724 and DAC7725 ideal for automatic test equipment, DAC-per-pin programmers, data acquisition systems, and closed-loop servo-control.
