Nisshinbo Micro Devices NJM2725

The NJM2725 is a dual high speed voltage feedback operational amplifier designed for use in applications requiring high speed and low noise features. The combination of 1.4nV/√Hz voltage noise and 160MHz bandwidth makes the product suitable for ultra-small signal and high frequency applications such as high speed photosensors, ultrasound sensors, active filters and other wideband applications. It can be easily configured as a low noise amplifier, and it can also be used as a high performance ADC front end in combination with rail-to-rail op amps.
