产品描述

The DAC7731 is a 16-bit Digital-to-Analog Converter (DAC) which provides 16 bits of monotonic performance over the specified operating temperature range and offers a +10V internal reference. Designed for automatic test equipment and industrial process control applications, the DAC7731’s output swing can be configured in a ±10V, ±5V, or +10V range. The flexibility of the output configuration allows the DAC7731 to provide both unipolar and bipolar operation by pin strapping. The DAC7731 includes a high-speed output amplifier with a maximum settling time of 5uµs to ±0.003% FSR for a 20V full-scale change and only consumes 100mW (typical) of power.

The DAC7731 features a standard 3-wire, SPI-compatible serial interface with double buffering to allow asynchronous updates of the analog output as well as a serial data output line for daisy-chaining multiple DAC7731s. A user programmable reset control forces the DAC output to either min-scale (0000h) or mid-scale (8000h), overriding both the input and DAC register values. The DAC7731 is available in a SSOP-24 package and three performance grades specified to operate from –40°C to +85°C.
