DESCRIPTION
The OPA642 provides a level of speed and dynamic
range previously unattainable in a monolithic op amp.
Using a unity gain stable voltage feedback architec-
ture with two internal gain stages, the OPA642 achieves
exceptionally low harmonic distortion over a wide
frequency range. The “classic” differential input pro-
vides all the familiar benefits of precision op amps,
such as bias current cancellation and very low invert-
ing current noise compared with wideband current
feedback op amps. Fast settling time, excellent differ-
ential 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 driv-
ers, wideband integrators and low distortion ADC buff-
ers. Where higher gain or even lower harmonic distor-
tion is required, consider the OPA643—a higher gain-
bandwidth and lower noise version of the OPA642
