The DAC7654 is a 16-bit, quad voltage output, digital-to-analog converter (DAC) with 16-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 DAC7654 can operate from a single +5V supply or from +5V and ?5V supplies.
Low power and small size per DAC make the DAC7654 ideal for automatic test equipment, DAC-per-pin programmers, data acquisition systems, and closed-loop servo-control. The DAC7654 is available in an LQFP package and is specified for operation over the ?40°C to +85°C temperature range.
