QW-R108-001,A
LOW VOLTAGE TELEPHONE
TRANSMISSION CIRCUIT WITH
DIALLER INTERFACE
DESCRIPTION
The UTC TEA1062/1062A is a bipolar integrated
circuit
performing
all
speech
and
line
interface
function,
required
in
the
fully
electronic
telephone
sets. It performs electronic switching
between
dialing
speech. The circuit is able to
operate down to D.C. line voltage of 1.6V (with
reduced performance) to facilitate the use of more
telephone sets in parallel.
FEATURES
* Low d.c. line voltage; operates down to 1.6V
(excluding polarity guard).
*Voltage regulator with adjustment static resistance.
*Provides supply with limited current for external
circuitry.
*Symmetrical high-impedance inputs (64k
Ω)for
dynamic, magnetic or piezoelectric microphones.
*Asymmetrical high-impedance inputs (32k
Ω)for
electret microphones.
*DTMF signal input with confidence tone.
DIP-16
SOP-16
*Mute input for pulse or DTMF dialing.
*Receivering amplifier for several types of earphones.
*Large amplification setting range on microphone
and earpiece amplifiers.
*Line
loss
compensation
facility ,
line
current
depedant
(microphone and earpiece amplifiers).
*Gain control adaptable to exchange supply.
*Possibility to adjust the d.c. line voltage.
