说明

The ONET4291TA is a high-speed transimpedance amplifier used in optical receivers with data rates up to 4.25 Gbps.

It features a low input referred noise, 2.8-GHz bandwidth, automatic gain control (AGC), 3.2-k transimpedance, and received signal strength indication (RSSI).

The ONET4291TA is available in die form and is optimized for use in a TO can.

The ONET4291TA requires a single 3.3-V supply, and its power-efficient design typically dissipates less than 56 mW. The device is characterized for operation from -40°C to 85°C ambient temperature.
