  • Product Introduction

The OPA842 offers an unprecedented level of speed and dynamic range for a monolithic operational amplifier. Using a unity-gain-stabilized, voltage-feedback architecture with two internal gain stages, the OPA842 achieves very low harmonic distortion over a wide frequency range. The classic differential inputs provide all the computational ideal familiar with the advantages of precision amplifiers, such as bias current cancellation and very low reverse current noise with wideband current differential gain/phase performance, low voltage noise, and high output current drive for the highest dynamic range applications of the OPA842.

The unity gain is stable, making the OPA842, especially the buffer of low-gain differential amplifiers, transimpedance amplifiers, 2-video gain for line drivers, wideband integration, and low-distortion analog-to-digital converters (ADCs).
