Transimpedance Amplifiers

ADI’s transimpedance amplifier family offers complete, single-chip solutions for converting photodiode current into a differential voltage output, supporting data rates from 155Mbps to 11.1Gbps. Featuring low input referred noise current, high input overload current and low power dissipation, applications include: 1x2x4x Fibre Channel, 10GBASE-LX4, SONET/SDH up to OC-192 FEC and 10Gb. Layouts are optimized for SFP ROSA packages such as TO-Cans.
