Description

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 DAC8571 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.
