Product Overview

The OPA657U is a high-gain bandwidth low-distortion voltage-feedback Operational Amplifier 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 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 with exceptional bandwidth and accuracy. Having a high 1.6GHz gain bandwidth product gives greater than 10MHz signal bandwidths up to gains of 160V/V (44dB). The very low input bias current and capacitance supports this performance even for relatively high source impedances. Broadband photodetector applications benefit from the low-voltage noise JFET inputs for the OPA657. The JFET input contributes virtually no current noise while for broadband applications, a low voltage noise is also required.
  • Available in high grade with improved DC specifications
  • Fast overdrive recovery
  • 1.6GHz High gain bandwidth
  • ±250µV Low-input offset voltage
  • 2pA Low-input bias current
  • 4.8nV/√Hz Low-input voltage noise
  • 70mA High-output current
