Description
The LTC™1456 is a complete single supply, rail-to-rail voltage output, 12-bit digital-to-analog converter (DAC) in an SO-8 package. It includes a rail-to-rail output buffer amplifier and an easy-to-use 3-wire cascadable serial interface. The LTC1456 includes a CLR pin that asynchronously 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.
