Semtech GN1035
GN1035 2.5 Gbps 跨阻放大器，带自动增益控制功能
The Gennum® GN1035 is a fully integrated, silicon germanium transimpedance amplifier; providing wideband, low noise pre-amplification of signal current from a photodetector.
It features differential outputs, and incorporates an automatic gain control mechanism to increase dynamic range, allowing input signals up to 2.6mA peak. A decoupling capacitor on the supply is the only external circuitry required.
Overview
Features
- +3.3V 单电源供电
- 功耗 125 mW（典型值）
