Product Summary
The SA5223D is a kind of AGC transimpedance amplifier. It is intended for signal recovery in wide-dynamic-range fiber optic receivers, such as SONET. It is also suitable for many other RF and fiber optic applications as a general purpose gain block. In addition, it 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. The typical applications include: (1)OC3 SONET preamp; (2)Current-to-voltage converters; (3)Wide-band gain block; (4)Medical and scientific instrumentation; (5)Sensor preamplifiers; (6)Single-ended to differential conversion; (7)Low noise RF amplifiers; (8)RF signal processing.
