OPA642

The OPA642 provides a level of speed and dynamic range previously unattainable in a monolithic op amp. Using a unity gain stable voltage feedback architecture with two internal gain stages, the OPA642 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 feedback op amps. Fast settling time, excellent differential gain/phase performance, low voltage noise and high output current drive make the OPA642 ideal for most high dynamic range applications.

Unity gain stability makes the OPA642 particularly suitable for low gain differential amplifiers, transimpedance amplifiers, gain of +2 video line drivers, wideband integrators and low distortion ADC buffers. Where higher gain or even lower harmonic distortion is required, consider the OPA643-a higher gainbandwidth and lower noise version of the OPA642
