The DAC7634 is a 16-bit, quad voltage output, digital-to-analog converter with specified 15-bit monotonic performance over the specified temperature range. It accepts 24-bit serial input data, has double-buffered DAC input logic (allowing simultaneous update of all DACs), and provides a serial data output for daisy-chaining multiple DACs. Programmable asynchronous reset clears all registers to a mid-scale code of 8000H or to a zero-scale of 0000H. The DAC7634 can operate from a single 5-V supply or from 5-V and -5 V supplies.
Low power and small size per DAC make the DAC7634 ideal for automatic test equipment, DAC-per-pin programmers, data acquisition systems, and closed-loop servo-control. The DAC7634 is available in a 48-lead SSOP package and offers specifications over the -40°C to 85°C temperature range.
