UTC MC34018 LINEAR INTEGRATED CIRCUIT

VOICE SWITCHED

SPEAKER-PHONE CIRCUIT

DESCRIPTION

SOP-28

The UTC MC34018 speaker-phone integrated circuit

incorporates the necessary functions to produce a high

quality hands-free speaker-phone system. The applications

include household and office speaker-phones, intercom

systems, hand free kit for mobile phones, and others.

FEATURES

*All necessary level detection and attenuation controls for a

hand-free telephone included.

*Background noise level monitoring with long time constant.

*Background sound level compensation for transmit and

receive levels as well as the background level.

*Wide operating dynamic range through signal compression.

*On-chip voltage regulators illuminate external regulators for

lining operation.

DIP-28

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

ohms)with peak limiting for speaker to minimize distortion.

*Chip Select pin for active/stand by operation.

*Volume control function for external volume control.

*Standard 28-pin plastic DIP and SOP package.
