The ADN2880 is a 3.3 V, low noise transimpedance amplifier (TIA) with a bandwidth of 2.5 GHz, optical sensitivity of -24.2 dBm, differential transimpedance of 4400 V/A, power dissipation of 70 mW, and differential output swing of 260 mV p-p. It is suitable for optical receivers with a data rate of 3.2 Gbps or below, and can be used in SONET/GbE/FC optical receivers and SFF-8472 compliant receivers. It is also compatible with PIN/APD-TIA receive optical subassemblies (ROSA).
The ADN2880 is a 3.3 V, high gain Silicon Germanium (SiGe) transimpedance amplifier designed for optical receiver applications. It converts the small signal current of a photo detector into a differential voltage output with a bandwidth of up to 2.5 GHz and an optical sensitivity of -24.2 dBm.
Key features include an on-chip RC filter (200 Ω, 20 pF) for low frequency cutoff without external components, an on-chip RSSI function for power monitoring, and a compact die size optimized for TO-Can-based packages like the TO-46 header.
