LT1994IDD#PBF

LINEAR TECHNOLOGY  LT1994IDD#PBF  差分放大器, 低失真, 1 放大器, 2 mV, 70 MHz, -40 °C, 85 °C

The is a high precision 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 225µA.
