DAC8574 说明
The DAC8574 is a low-power, quad channel, 16-bit buffered voltage output DAC. Its on-chip precision output amplifier allows rail-to-rail output swing to be achieved. The DAC8574 utilizes an I²C compatible two wire serial interface supporting high-speed interface mode with address support of up to sixteen DAC8574’s for a total of 64 channels on the bus.
The DAC8574 requires an external reference voltage to set the output range of the DAC. The DAC8574 incorporates a power-on-reset circuit that ensures that the DAC output powers up at zero volts and remains there until a valid write takes place to the device. The DAC8574 contains a power-down feature, accessed via the internal control register, that reduces the current consumption of the device to 200nA at 5V.
