16-Bit, Dual Voltage Output DAC With Parallel Interface And Reset To Min-Scale

The DAC7642 and DAC7643 are dual channel, 16-bit, voltage output digital-to-analog Converters (DACs) which provide 15-bit monotonic performance over the specified temperature range. They accept 16-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 Programmable asynchronous reset clears all Registers to a mid-scale code of 8000H DAC7642 or to a zero-scale code of 0000H DAC7643 . These DACs CAN operate from a single +5V supply or from +5V and ?5V supplies, providing an output range of 0 to +2.5V or ?2.5V to +2.5V, respectively.
Low power and small size per DAC make the DAC7642 and DAC7643 ideal for Automatic test equipment, DAC-per-pin programmers, data acquisition systems, and closed-loop servo-control. The DAC7642 and DAC7643 are available in a LQFP-32 package and specified over a ?40C to +85C temperature range.
