DAC8531 说明

The DAC8531 is a low-power, single, 16-bit buffered voltage output Digital-to-Analog Converter (DAC). Its on-chip precision output amplifier allows rail-to-rail output swing to be achieved. The DAC8531 uses a versatile three-wire serial interface that operates at clock rates up to 30MHz and is compatible with standard SPITM, QSPITM, MicrowireTM, and Digital Signal Processor (DSP) interfaces.

The DAC8531 requires an external reference voltage to set the output range of the DAC. The DAC8531 incorporates a power-on reset circuit that ensures that the DAC output powers up at 0V and remains there until a valid write takes place to the device. The DAC8531 contains a power-down feature, accessed over the serial interface, that reduces the current consumption of the device to 200nA at 5V.
