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.
The AD5625R/AD5645R/AD5665R have an on-chip reference.
The LFCSP versions of the AD5625R/AD5645R/AD5665R have a 1.
25 V or 2.
5 V, 10 ppm/°C reference, giving a full-scale output range of 2.
5 V or 5 V; the TSSOP versions of the AD5625R/ AD5645R/AD5665R have a 2.
5 V, 5 ppm/°C reference, giving a full-scale output range of 5 V.
The WLCSP has a 1.
25 V reference.
The on-chip reference is off at power-up, allowing the use of an external reference.
The internal reference is enabled via a software write.
The AD5625/AD5665 require an external reference voltage to set the output range of the DAC.
The device incorporates a power-on reset circuit that ensures that the DAC output powers up to ...
