GL6962/GL6962A

Low Voltage Universal Speech Network

Description

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.

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

Symmetrical high-impedance inputs (64k¥ Ø

) for

dynamic, magnetic or piezo-electric microphones

Asymmetrical high-impedance inputs(32k¥ Ø

)

for electric microphones

DTMF signal input with confidence tone

MUTE input for pulse or DTMF dialing

(GL6962)

MUTE

input for pulse or DTMF dialing

(GL6962A)

Receiving amplifier for dynamic, magnetic or

piezo-electric earpieces.

Large gain setting ranges on microphone and

earpiece amplifiers.

Line loss compensation (line current dependent)

for microphone and earpiece amplifiers

Gain control curve adaptable to exchange supply

DC line voltage adjustment facility

Packaged in 16 DIP/SOP.
