LINEAR INTEGRATED CIRCUIT

VOICE SWITCHED

SPEAKER-PHONE CIRCUIT

SOP-28

DESCRIPTION

As a voice switched speaker-phone integrated circuit, the UTC

MC34118 includes the necessary amplifiers, attenuators, level

detectors and control algorithm.

DIP-28

To form the UTC MC34118’s internal circuit, there is an internal

microphone amplifier with adjustable gain and mute control, internal

transmit and Receive attenuators (operate in a complementary

manner), level detectors at both input and output of both attenuators,

and background noise monitors for both the transmit and receive

channels.

SDIP-28

The dial tone can be pretended from being attenuated by the

receive background noise monitor circuit by a dial tone detector.

There are also two line driver amplifiers which can be used to form a

hybrid network in conjunction with an external coupling transformer. A

high-pass filter can be used for other filtering functions, and especially

to filter out 60Hz noise in the receive channel.

Lead-free:

Halogen-free: MC34118G

MC34118L

The UTC MC34118 which requiring typically 5mA may be

operated from a power supply, or it can be powered from the

telephone line.

FEATURES

* Attenuator gain range: 52dB (between Transmit and Receive)

* For line-powered applications : 3~6.5V low voltage operation

* For improved sensitivity :4-point signal sensing

* For Transmit and Receive paths: background noise monitors

* External resistors set microphone amplifier gain

* Mute function included

* Chip disable: active or standby operation

* During dial tone presence: dial tone detector to inhibit receive idle

mode
