Description

The GL6965 is a bipolar integrated circuit for use in electronic telephones.

The GL6965 has low operating voltage, it provides an excellent branch performance.

It has line voltage increasing circuit by the exter-nal terminal. Transmitting and receiving gains automatically vary according to the line current.

Features

• Externally adjustable transmitting, receiving and Sidetone gains.

• Switching between transmitting output and DTMF output is possible.

• Direct interface with light and compact ceramic transmitter-receiver is possible.

• Receiver follow impedance type can also be used.

• Gain is automatically controlled according to the line current (Auto-PAD function).

• The line voltage can be increased by the external terminal (Up function).

• PKG is 20 pin DIP.
