OPA2107AU Description

The OPA2107AU from Texas Instruments is a high-performance, dual-channel general-purpose operational amplifier (op-amp) from the Difet® series, designed for precision analog applications. Operating within a 9V to 36V supply range, it delivers 4.5 MHz gain bandwidth product (GBW) and an ultra-low input bias current of 4 pA, making it ideal for high-impedance sensor interfaces and precision signal conditioning. With a slew rate of 18V/µs and low input offset voltage (100 µV), it ensures fast, accurate signal amplification. The device is RoHS3 compliant and packaged in an 8-pin SOIC tube, suitable for surface-mount applications.
