iT3021

iT3021 2.5 Gb/s High-Sensitivity Limiter Amplifier Description The iT3021 is a limiting amplifier for use as a post amplifier in optical receivers. Signals as small as +/-7 mVpp differential can be amplified to 1.28 Vpp differential. Offset correction and output voltage control are provided. Both AC and DC coupling are allowed at the input and output. The high sensitivity allows the device to be used at the output of a transimpedance amplifier.
