Description

DATASHEET a single OPA657 gain stage with exceptional. Low-Input Voltage Noise: 4.8 nV/ Hz bandwidth and accuracy. Having a high 1.6-GHz gain bandwidth product Jul 3, 2015 the OPA657 is its lower voltage noise and its much lower input capacitance. And. (LTC6268, continued from page 1). The calculated CV + I Jul 3, 2015 AND COMPETITIVE OPA657 . The CV + I noise is a useful figure of merit for comparing op amps, but it does have a dependency on frequency. Jun 10, 2014 transimpedance gains (> 100k ) will benefit from the low input noise current of a JFET input op amp such as the. OPA657 . Unity-gain stability 7. Unity-Gain Stable FET-Input.
