DAC7724

12 位四路电压输出数模转换器

The 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. The DAC7724 and DAC7725 are available in a PLCC-28 or a SO-28 package, and offer guaranteed specifications over the –40°C to +85°C temperature range.
