TECHNICAL DATA

KK34118

Voice Switched Speakerphone Circuit

The KK34118 Voice Switched Speakerphone Circuit incorporates the

necessary amplifiers, attenuators, level detectors, and control algorithm to

form the heart of a high quality hands-free speakerphone system. Included

are a microphone amplifier with adjustable gain and MUTE control,

Transmit and Receive attenuators which 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. A

Dial Tone Detector prevents the dial tone from being attenuated by the

Receive background noise monitor circuit. Also included are 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 to filter out 60 Hz noise in the receive channel, or for other

filtering functions. A Chip Disable pin permits powering down the entire

circuit to conserve power on long loops where loop current is at a

minimum.

ORDERING INFORMATION

KK34118N Plastic

KK34118DW SOIC

T_A= -25° to 70° C for all packages

The KK34118 may be operated from a power supply, or it can be powered

from the telephone line, requiring typically 5.0 mA. The KK34118 can be

interfaced directly to Tip and Ring (through a coupling transformer) for

stand-alone operation, or it can be used in conjunction with a handset

speech network and or other features of a feature phone.
