PBL38571 Description
PBL 38571 is a monolithic integrated speech transmission circuit for use in electronic telephones and as DECT line interface with balanced in - and output. It is designed to acodate either a low impedance dynamic microphone or an electret microphone that can be supplied from the circuits own DC - supply. A signal summing point at the transmitter input is available.
