The internal reference can be bypassed to use an external reference to suit the dc accuracy and temperature drift requirements of the application. A 10-bit parallel output data bus is provided with 3-state outputs. For power sensitive systems, a standby mode is provided which reduces power consumption to 336 µW. Also, if using external voltage reference, then the internal VREF circuit can be powered down. The analog input is differential, which provides excellent common-mode noise rejection as well as superior performance from the ADS5102/3.
