Description

The LT1994 is a high precision, very low noise, low distortion, fully differential input/output amplifier optimized for 3V, single supply operation. The LT1994?s 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.The LT1994 output can swing rail-to-rail and is capable of sourcing and sinking up to 85mA. In addition to the low distortion characteristics, the LT1994 has a low input referred voltage noise of 3nV/?Hz. This part maintains its performance for supply voltages as low as 2.375V. It draws only 13.3mA of supply current and has a hardware shutdown feature that reduces current consumption to 225?A.The LT1994 is available in an 8-pin MSOP or 8-pin DFN package.Applications Differential Input A/D Converter Driver Single-Ended to Differential Conversion Differential Amplifier cation with Common Mode Translation Rail-to-Rail Differential Line Driver/Receiver Low Voltage, Low Noise, Differential Signal Processing
