Description

General part information

LTC1257 Series

LTC1257 is a complete single supply, 12bit voltage output D/A converter (DAC) in a SO-8 package. The LTC1257 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 8-pin SO package and operation with no external components provide the smallest 12bit D/A system available. Applications include digital offset/gain adjustment, industrial process control and automatic test equipment.
