the dac6573 is a low-power quad channel 10-bit buffered voltage output dac. 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 of the device to 200 na at 5 v. view all in datasheet
