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. SOP-16 DIP-18 FEATURES *Settable gain dynamics (25 or 50dB) *Low power consumption, totally 1.0mA at 3.3V typical.
