DAC6574IDGSR is a low-power, four channel, 10 bit buffered voltage output DAC. Its on-chip precision output amplifier can achieve rail to rail output swing. The DAC6574IDGSR adopts a two wire serial interface compatible with I2C, supports high-speed interface mode, and supports up to 4 DAC6574IDGSRs with addresses. There are a total of 16 channels on the bus. DAC6574 uses VDD and GND to set the output range of DAC. The DAC6574 integrates a power on reset circuit to ensure that the DAC output is powered on at zero volts and maintained at that voltage until effective writing is performed on the device. The DAC6574IDGSR includes a turn off function for each channel, which can reduce the device's current consumption to 200 nA at 5 V through internal control registers for communication. The low power consumption of this device during normal operation makes it very suitable for portable battery powered devices. When VDD=5 V, the power consumption is less than 3mW, and in power-saving mode, the power consumption drops to 1 μ W. TI provides various data converters with I2C interfaces.
