OPA 657
SBOS197B – DECEMBER 2001 – REVISED MAY 2004
1.6GHz, Low-Noise, FET-Input OPERATIONAL AMPLIFIER
FEATURES
q q q q q HIGH GAIN BANDWIDTH PRODUCT: 1.6GHz HIGH BANDWIDTH 275MHz (G = +10) LOW INPUT OFFSET VOLTAGE: ±0.25mV LOW INPUT BIAS CURRENT: 2pA LOW INPUT VOLTAGE NOISE: 4.8nV/ Hz
DESCRIPTION
The OPA657 combines a high gain bandwidth, low distor-tion, 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.
