OPA842 pdf,宽带低失真单位增益稳定的电压反馈运算放大器

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.
