CIC Hybrid

GS3022 - DATA SHEET

DESCRIPTION

The GS3022 hybrid contains Gennum’s GK509 class A

amplifier and a single input coupling capacitor. The extremely

small size of the hybrid allows it to easily fit into many CIC and

ITC applications.

Block A of the GK509 is a low noise inverting amplifier with an

open loop voltage gain of typically 56 dB. The closed loop

gain is set by the ratio of input resistance to feedback

resistance.

The output stage is a class A current drive amplifier. The

current that flows in the transducer is the ratio of the 30 mV

reference voltage to the resistance to ground at pad 1 on the

hybrid. With no external RE the trandsducer current is typically

240 µA, which makes it suitable for high impedance receivers.
