资 源 简 介
The DAC7573 is a low-power, quad channel, 12-bit buffered voltage output DAC. Its on-chip precision output amplifier allows rail-to-rail output swing to be achieved. The DAC7573 uTIlizes an I²C compaTIble two wire serial interface supporTIng high-speed interface mode with address support of up to sixteen DAC7573s for a total of 64 channels on the bus.
The DAC7573 requires an external reference voltage to set the output range of the DAC. The DAC7573 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 DAC7573 contains a power-down feature, accessed via the internal control register, that reduces the current consumption of the device to 200 nA at 5 V.
