Its on-chip precision output amplifier allows rail-to-rail output swing. The DAC6573 utilizes an I2C compatible two wire serial interface supporting high-speed interface mode with address support of up to sixteen DAC6573s for a total of 64 channels on the bus. The DAC6573 requires an external reference voltage to set the output range of the DAC. The DAC6573 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 in the device. The DAC6573 contains a power-down feature, accessed via the internal control register, that reduces the current consumption...
