1 / 31 page 16-Bit, Quad Voltage Output, Serial Input DIGITAL-TO-ANALOG CONVERTER DAC7734 DESCRIPTION The DAC7734 is a 16-bit, quad voltage output, digital-to- analog converter (DAC) with ensured 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 DAC7734 can operate from a single +15V supply or from +15V and –15V, and +5V supplies. Low power and small size per DAC make the DAC7734 ideal for automatic test equipment, DAC-per-pin programmers, data acquisition systems, and closed-loop servo-control. The DAC7734 is available in a 48-lead SSOP package and offers ensured specifications over the –40 °C to +85°C temperature range.
