® DAC7624 DAC7625 12-Bit Quad Voltage Output DIGITAL-TO-ANALOG CONVERTER Features q LOW POWER: 20m W q UNIPOLAR OR BIPOLAR OPERATION q SETTLING TIME: 10µs to 0.012% q 12-BIT LINEARITY AND MONOTONICITY: - 40°C to +85°C q RESET TO MID-SCALE (DAC7624) OR ZERO-SCALE (DAC7625) q DATA READBACK q DOUBLE-BUFFERED DATA INPUTS DESCRIPTION The DAC7624 and DAC7625 are 12-bit quad voltage output digital-to-analog converters with guaranteed 12bit 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 doublewide or a 28-lead SOIC package, and offer guaranteed specifications over the - 40°C to +85°C temperature range.
