GENERAL DESCRIPTION

The AD5625R/AD5645R/AD5665R, AD5625/AD5665 members of the nanoDAC family, are low power, quad, 12-, 14-,16-bit buffered voltage-out DACs with/without an on-chip reference. All devices operate from a single 2.7 V to 5.5 V supply, are guaranteed monotonic by design and have an I2C compatible serial interface .
