4.25 Gbps 3.3V Low Noise Transimpedance Amplifier

GENERAL DESCRIPTION The ADN2882 is a 3.3 V high gain SiGe transimpedance amplifier (TIA) which converts the small signal current of a photo detector to a large differential voltage output. The ADN2882 features a typical 475 nA input-referred noise, enabling an optical sensitivity of ?22 dBm (0.85
