Product details

Description

The PBL 388 13 contains all the necessary circuitry, amplifiers, detectors, comparator and control functions to implement a high performance, voice-switched, loudspeaking, ”hands-free ” telephone.

Features

Minimum of external components needed for function. Selectable gain dynamics. (25 or 50 dB) Direct telephone line powered solution (patented). Low power consumption: ≈1mA at 3.3V (typical) for speech switching, audio power amplifier quiscent current ≈1mA. Drives an 25 - 50 ohm loudspeaker without a transformer. Background noise compensation in the transmitting channel with hold function at receive. Input amplifiers of both channels have balanced inputs. Exellent noise performance. Encapsulated i.
