Product Summary

The LTC1257IS8#TR is a complete single supply, 12-bit voltage output D/A converter (DAC) in an SO-8 package. The LTC1257IS8#TR 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 to 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 LTC1257IS8#TR ideal for battery-powered applications. The applications of the LTC1257IS8#TR include Digital Offset/Gain Adjustment, Industrial Process Control, Automatic Test Equipment.
