LINEAR INTEGRATED CIRCUIT

VOICE SWITCHED

SPEAKER-PHONE CIRCUIT



DESCRIPTION

The UTC MC34018 speaker-phone integrated circuit includes

all the active circuitry and control functions to implement a high

quality hands-free telephone system. The circuit includes a

microphone amplifier, a speaker amplifier, level detectors, a

background sound level monitoring system in both the transmit and

receive channels and an attenuation system which can control the

transmit and receive levels as well as the background level.

The

applications

include

household

and

office

speaker-phones, intercom systems, hand free kit for mobile

phones, and others.



FEATURES

* Chip Select pin for Power conservation (active/standby mode).

* Integrated all necessary active circuitry for a hand-free telephone

into one single chip.

* Operating under wide dynamic range through signal compression

technology.

* Build-In voltage regulators illuminate external regulators for lining

operation.

* Monitoring system for background noise level.

* Background sound level compensation for transmit and

receive levels as well as the background level.

* Power audio amplifier for typical 100mW output (into 25Ω) with

peak limiting for speaker to minimize distortion.

* Volume control function for external volume control circuit.
