The LTC1257IS8#PBF is a complete single-supply 12-bit voltage output Digital-to-analog Converter (DAC) includes an output buffer amplifier, 2.048V voltage reference and an easy to use 3-wire cascadable serial interface. An external reference can be used to override the internal reference and extend the output voltage range to 12V. The power supply current is a low 350μA when operating from a 5V supply, making the LTC1257 ideal for battery-powered applications.
