General 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.

Key Features

  • high line current capability on a small footprint. Function compatible with the PBL 3781 family of speech circuits. Key features.
  • Minimum number of external components, 5 capacitors and 10 resistors. Easy adaption to various market needs. Mute control input for operation with DTMF - generator. Transmitter and receiver gain regulation for automatic loop loss compensation. Disconnectable. Extended current and voltage range 5 - 130 mA, down to 2 V. Differential microphone input for good.
