Overview
The DAC716UK is a 16-bit digital-to-analog converter (DAC) produced by Texas Instruments. It is a complete monolithic D/A converter that includes a +10V temperature-compensated voltage reference, a current-to-voltage amplifier, and a high-speed synchronous serial interface. The device is designed to provide high precision and efficiency in converting digital signals into analog voltage outputs. It features gain and offset adjustments, which can be set via external potentiometers or external D/A converters, and includes built-in protection against short-circuiting to ground. The DAC716UK is available in a 16-pin SOIC package and is specified over the 0°C to +70°C temperature range.
