DESCRIPTION
The OPA643 provides a level of speed and dynamic
range previously unattainable in a monolithic op amp.
Using a de-compensated voltage feedback architec-
ture with two internal gain stages, the OPA643 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. High slew rate and open-loop gain,
along with low input noise and high output current

drive make the OPA643 ideal for very high dynamic
range requirements.
The high gain bandwidth product for the gain 3
stable OPA643 makes it particularly suitable for
wideband transimpedance amplifiers and moderate gain
IF amplifier applications. External compensation
techniques may be used to apply the OPA643 at low
gains giving exceptionally low distortion and frequency
response flatness. Where unity gain stability with
comparable distortion performance is required, consider
the OPA642.
