Description

The SA5223 is a wide-band, low-noise transimpedance amplifier with differential outputs, incorporating AGC and optimized for signal recovery in wide-dynamic-range fiber optic receivers, such as SONET. The SA5223 is also suited for many other RF and fiber optic applications as a general purpose gain block.

The SA5223 is the first AGC amplifier to incorporate internal AGC loop hold capacitor, therefore, no external components are required. The internal AGC loop enables the SA5223 to effortlessly handle bursty data over a range of nA to mA of signal current, positive direction (sinking) only.
