LT1994CDD#PBF

LT1994 is a high precision, very low noise, low distortion, fully differential input/output amplifier optimized for 3V, single-supply operation. Its output common mode voltage is independent of the input common mode voltage and is adjustable by applying a voltage on the VOCM pin. A separate internal common mode feedback path provides accurate output phase balancing and reduced even-order harmonics. This makes the LT1994 ideal for level shifting ground referenced signals for driving differential input, single-supply ADCs. Typical applications are differential input A/D converter driver, single-ended to differential conversion, differential amplification with common mode translation, rail-to-rail differential line driver/receiver, low voltage, low noise, differential signal processing.
