OPA643 - Wideband Low Distortion / High Gain OPERATIONAL AMPLIFIER

Download the OPA643 datasheet PDF. This datasheet also covers the OPA643_Burr variant, as both devices belong to the same wideband low distortion / high gain operational amplifier family and are provided as variant models within a single manufacturer datasheet.

Description

The OPA643 provides a level of speed and dynamic range previously unattainable in a monolithic op amp.

Using a de-compensated voltage feedback architecture with two internal gain stages, the OPA643 achieves exceptionally low harmonic distortion over a wide frequency range.
