OPA2380AIDGKR

精密，高速互阻抗放大器 Precision, High-Speed Transimpedance Amplifier

DESCRIPON

The OPA380 family of transimpedance amplifiers provides high-speed 90MHz Gain Bandwidth [GBW] operation, with extremely high precision, excellent long-term stability, and very low 1/f noise. It is ideally suited for high-speed photodiode applications. The OPA380 features an offset voltage of 25µV, offset drift of 0.1µV/°C, and bias current of 50pA. The OPA380 far exceeds the offset, drift, and noise performance that conventional JFET op amps provide.
