Product Summary
The OPA657UB 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 of the OPA657UB will see improved noise and bandwidth using this decompensated, high gain bandwidth amplifier. Very low level signals can be significantly amplified in a single OPA657UB gain stage with exceptional bandwidth and accuracy. Having a high 1.6GHz gain bandwidth product will give > 10MHz signal bandwidths up to gains of 160V/V (44dB). The very low input bias current and capacitance of the OPA657UB will support this performance even for relatively high source impedances.
