SA5223

Wide dynamic range AGC transimpedance amplifier(150MHz)

1995 Oct 24

853-1816 15939

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 part 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.

FEATURES

• Extremely low noise:1.17pA Hz
