LTC1654CGN#PBF

LTC®1654 is a dual, rail-to-rail voltage output, 14bit digital-to-analogue converter (DAC). It includes output buffer amplifiers and a flexible serial interface. The LTC1654 has REFHI pins for each DAC that can be driven up to VCC. The output will swing from 0V to VCC in a gain of 1 configuration or VCC/2 in a gain of 1/2 configuration. The LTC1654 also has shutdown capability, power-on reset and a clear function to 0V. Application includes digital calibration, industrial process control, automatic test equipment, offset/gain adjustment, multiplying DAC.
