To facilitate the assembly in small form factor packages, such as TO-46 headers, the ADN2880 provides an on-chip RC filter (200 ohms, 20 pF) and features 20kHz low frequency cutoff without using an external capacitor. An on-chip RSSI circuit, which generates voltage proportional to average photo-diode current, is also available for power monitoring and assembly alignment.
The ADN2880 is available in die form. With chip area of 1.2 mm x 0.7 mm, the TIA layout is specifically optimized for TO-Can-based packages.
