DAC714 说明
The DAC714 is a complete monolithic digital-to-analog converter including a +10V temperature compensated reference, current-to-voltage amplifier, a high-speed synchronous serial interface, a serial output which allows cascading multiple converters, and an asynchronous clear function which immediately sets the output voltage to midscale.
The output voltage range is ±10V, ±5V, or 0 to +10V while operating from ±12V or ±15V supplies. The gain and bipolar offset adjustments are designed so that they can be set via external potentiometers or external D/A converters. The output amplifier is protected against short circuit to ground.
The 16-pin DAC714 is available in a plastic 0.3" DIP, ceramic 0.
