The ADN2882 is a compact, high performance 3.3 V power supply SiGe transimpedance amplifier (TIA) optimized for small form factor 4.25Gbps optical modules compliant with SFF-8472 receivers, PIN/APD-TIA receive optical subassembly, SONET/GbE/FC optical receivers, transceivers, and transponders.
The Analog Devices ADN2882 is a compact, high-performance single-chip solution designed as a 3.3 V power supply SiGe transimpedance amplifier (TIA). It is optimized for small form factor 4.25 Gbps metro-access Ethernet PIN/APD-TIA modules and 1x/2x/4x Fibre channel receiver applications, meeting OC48 SR/IR sensitivity requirements.
The device features a low input referred noise current of 600 nA enabling -22 dBm sensitivity and a minimum bandwidth of 3.2 GHz for up to 4.25 Gbps operation. It includes an on-chip photodiode filter network with a 15 kHz low frequency cutoff, allowing assembly in small form factor packages like TO-46 or TO-56 headers without external components.
