Dual High Speed Voltage Feedback Operational Amplifier for Ultra-Small Signal and High Frequency Applications

Nisshinbo Micro Devices Inc. has introduced the new dual high-speed voltage feedback operational amplifier NJM2725 that combines the high-speed performance of 160 MHz with the low-noise performance of 1.4 nV/√Hz, which is ideal for ultrasonic sensors that monitor distance and material conditions without contact. Designed for ease of use in high-speed and low-noise applications, this amplifier is suitable for high-speed photosensors, ultrasound sensors, and active filters.

NJM2725 amplifier 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. This device is stable for Gain ≥ 2 or Gain ≤ -1. Packages for this device are the 8pin SOP and the 8pin MSOP8 (VSP8) and are offered in the extended industrial temperature grade of -40°C to 125°C.
