OPA657 datasheet



The OPA657 combines a high gain bandwidth, low distortion, voltage-feedback op amp with a low voltage noise JFET-input stage to offer a very high dynamic range amplifier for high precision ADC (Analog-to-Digital Converter) driving or wideband transimpedance applications.

Photodiode applications will see improved noise and bandwidth using this decompensated, high gain bandwidth amplifier.
