6GHz, Low-Noise, FET-Input OPERATIONAL AMPLIFIER FEATURES q HIGH GAIN BANDWIDTH PRODUCT: 1.
6GHz q HIGH BANDWIDTH 275MHz (G = +10) q LOW INPUT OFFSET VOLTAGE: ±0.
25mV q LOW INPUT BIAS CURRENT: 2pA q LOW INPUT VOLTAGE NOISE: 4.
8nV/ Hz q HIGH OUTPUT CURRENT: 70mA q FAST OVERDRIVE RECOVERY APPLICATIONS q WIDEBAND PHOTODIODE AMPLIFIER q WAFER SCANNING EQUIPMENT q ADC INPUT AMPLIFIER q TEST AND MEASUREMENT FRONT END q HIGH GAIN PRECISION AMPLIFIER 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.
Very low level signals can be significantly amplified in a single OPA657 gain stage wit...
