LTC1257IS8#TRPBF

LTC1257IS8#TRPBF is a complete single supply, 12-bit voltage output D/A converter. It 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. The space-saving package and operation with no external components provide the smallest 12bit D/A system available. Application includes digital offset/gain adjustment, industrial process control, automatic test equipment.
