TECHNICAL DATA
LINEAR INTEGRATED CIRCUIT
VOICE SWITCHED SPEAKER PHONE CIRCUIT
KL34018
DESCRIPTION
The KL34018 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.
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.

* Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device.
These are stress ratings only and functional operation of the device at these or any other conditions beyond those
indicated under “recommended operating conditions” is not implied.
Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
