The DAC8571 is a small low-power, 16-bit voltage output DAC with an I2C compatible two-wire serial interface. Its on-chip precision output amplifier allows rail-to-rail output swing and settles within 10 microseconds. The DAC8571 architecture is 16-bit monotonic, and factory trimming typically achieves ±4 mV absolute accuracy at all codes. The DAC8571 requires an external reference voltage to set its output voltage range.
●The low power consumption and small size of this part make it ideally suited to portable battery operated equipment. The power consumption is typically 800 µW at VDD = 5 V reducing to 1 µWin power-down mode.
●The DAC8571 incorporates a 2-wire I2C interface. Standard, fast, and high-speed modes of I2C operation are all supported up to 3.4 MHz serial clock speeds. Multichannel synchronous data update and power-down operations are supported through the I2C bus. DAC8571 is also capable of transmitting the contents of its serial shift register, a key feature for I2C system verification.
