Low-Noise Low-Offset RR Out Fully Differential OPAMP

Overview

The PVOA201LN is a low power, low noise, fully-differential op amp with a rail-to-rail output and an input common-mode range including the negative power supply rail. This amplifier is an ideal candidate for low power data acquisition systems, handhelds, and other portable devices where low power dissipation is important.

The amplifier features an adjustable output common mode control for optimizing the common mode level, ideal for driving analog-to-digital converters. The device allows easy translation from single-ended signals to differential signals on the input or on the output. The PVOA201LN is also ideal for level shifting ground referenced signals to common mode levels within the output common mode range of the amplifier.

With a low input referred voltage noise of 3.5nV/?Hz and single supply operation from +2.5V to +3.6V, the PVOA201LN is well suited for a variety of low power / low noise data acquisition and signal processing applications.
