UTC L388 12 LINEAR INTEGRATED CIRCUIT
VOICE-SWITCH CIRCUIT FOR
HANDSFREE SPEAKERPHONE
TAM
DESCRIPTION
The UTC L388 12 contains all the necessary circuitry,
amplifiers, detectors, comparators and control functions to
implement a high performance, voice-switched, ”hands-free”
function in an answering machine.
The UTC L 388 12 is designed for answering machines
that are either powered from the telephone line or from a
mains powered dc. supply.
Filtering of both the audio and control signals in both
transmitter and receiver channels possible.
An external loudspeaker amplifier has to be used, normally
the same as used for the answering machine.
FEATURES
*Settable gain dynamics (25 or 50dB)
*Low power consumption, totally 1.0mA at 3.3V typical.
*Background noise compensation in the transmitting channel
*with hold function.
*Excellent noise performance.
*Both channel input amplifiers have balanced inputs.
*Minimum of external components needed for function.
