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.
