GL6962 Overview
The GL6962 and GL6962A are bipolar integrated circuits that perform all speech and line interface functions required in fully electronic telephone sets. They perform electronic switching between dialing and speech. The ICs operate at line voltage down to 1.6V DC (with reduced performance) to facilitate the use of more telephone sets connected in parallel.
GL6962 Key Features
- Low DC line voltage: operates down to 1.6V (excluding polarity guard)
- Voltage regulator with adjustable static resistance
- Provides a supply for external circuits
- Asymmetrical high-impedance inputs(32k )
- DTMF signal input with confidence tone
- MUTE input for pulse or DTMF dialing
- MUTE input for pulse or DTMF dialing
- Receiving amplifier for dynamic, magnetic or
- Large gain setting ranges on microphone and
- Line loss pensation (line current dependent)
