GL6965 - Telephone Speech Network with Dialer Interface

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.

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 2.
