The OPA842 provides a level of speed and dynamic range previously unattainable in a monolithic op amp. Using unitygain stable, voltage-feedback architecture with two internal gain stages, the OPA842 achieves exceptionally low harmonic distortion over a wide frequency range. The "classic" differential input provides all the familiar benefits of precision op amps, such as bias current cancellation and very low inverting current noise compared with wideband current differential gain/phase performance, low-voltage noise, and high output current drive make the OPA842 ideal for most high dynamic range applications.
