DAC7625

12 位四路电压输出数模转换器

The DAC7624 and 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 DAC7624 or to a zero-scale of 000H DAC7625. The DAC7624 and DAC7625 can operate from a single +5V supply or from +5V and –5V supplies.

Low power and small size per DAC make the DAC7624 and DAC7625 ideal for automatic test equipment, DAC-per-pin programmers, data acquisition systems, and closed-loop servo-control. The DAC7624 and DAC7625 are available in a 28-pin plastic double-wide or a 28-lead SOIC package, and offer guaranteed specifications over the -40°C to +85°C temperature range.
