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 A/W PIN). With a bandwidth of 3.5 GHz, the ADN2882 allows a data rate operation up to 4.25 Gbps. Typical power dissipation is 80 mW. To facilitate the assembly in small form factor packages, such as TO-46 headers, the ADN2882 provides an on-chip RC filter (200 , 20 pF) and features a 12 kHz low frequency cutoff without using an external capacitor. An on-chip RSSI circuit, which generates a voltage proportional to the average photodiode current, is available for power monitoring and assembly alignment.
