0.007%/0.008°

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.

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

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
