The ADN2880 is a 3.3 V, high gain SiGe transimpedance amplifier (TIA). The TIA converts the small signal current of a photo detector into differential voltage output. The ADN2880 features a 315 nA typical input-referred noise, enabling an optical sensitivity of −24.2 dBm (0.85 A/W PIN). With a bandwidth of 2.5 GHz, the ADN2880 allows a data rate operation up to 3.2 Gbps. Typical power dissipation is approximately 70 mW.
To facilitate the assembly in small form factor packages, such as TO-46 headers, the ADN2880 provides an on-chip RC filter (200 Ω, 20 pF) and features a 20 kHz low frequency cutoff without using an external capacitor. An on-chip RSSI circuit, which generates a voltage proportional to the average photo-diode current, is also available for power monitoring and assembly alignment.
The ADN2880 is available in die form. With a chip area of 1.2 mm × 0.7 mm, the TIA layout is specifically optimized for TO-Can-based packages.
