Description

The LTC®1257 is a complete single supply, 12-bit voltage output D/A converter (DAC) in an SO-8 package. The LTC1257 includes an output buffer amplifier, 2.048V voltage reference and an easy to use three-wire cascadable serial interface. An external reference can be used override the internal reference and extend the output voltage range to 12V. The power supply current is a low 350mA when operating from a 5V supply, making the LTC1257 ideal for battery-powered applications. The spacesaving 8-pin SO package and operation with no external components provide the smallest 12-bit D/A system available.
