High input impedance amplifier CA3440

Published:2012/9/11 20:17:00 Author:Ecco | Keyword: High input, impedance amplifier | From:SeekIC

This circuit takes advantage of the leakage of low power, high input impedance, frequency and capacity of the excellent CA3440. Only one input coupling capacitor of 500 pF is needed to achieve a 20 Hz, -3 dB low frequency response. ..
