Transimpedance amplifier
Transimpedance amplifier
The vsc7911 transimpedance amplifier converts a photodiode current into a differential output voltage. Typical application is in front-end receivers for fiber-optic communication channels. The amplifier includes an integrated agc function to sense a wide range of input currents. The agc loop time constant can be changed with an off-chip capacitor. Other features include sonet/sdh compatibility, 622-Mbit/sec operation, low noise, and a single 5V power supply.
