... The LTC1456 includes a CLR pin that asynchro- nously clears the DAC to zero scale. The LTC1456 has an internal 2.048V reference and a full- scale output of 4.095V. It operates on a 4.5V to 5.5V supply, dissipating 2.2mW. The low power supply current and the space saving SO-8 package make the LTC1456 ideal for battery-powered applications ...
