Overview
The AD5645RBRUZ is a member of the nanoDAC family from Analog Devices Inc., specifically part of the AD5625R/AD5645R/AD5665R and AD5625/AD5665 series. These devices are low-power, quad, 14-bit buffered voltage-out digital-to-analog converters (DACs) that can operate with or without an on-chip reference. They are designed to operate from a single 2.7 V to 5.5 V supply and are guaranteed to be monotonic. The AD5645RBRUZ features an I2C-compatible serial interface, making it easy to integrate into a wide range of systems.
