PBL38814 Voice - switched 2-channel Circuit with loudspeaker amplifier

The PBL 388 14 contains all the necessary circuitry, amplifiers, detectors, comparator and control functions to implement a high performance voice switched handsfree two- way communication system. The gain dynamics (attenuation between channels) is selectable (25dB or 50dB) via a separate pin. A ba.

PBL38814 Features

* the power amplifiers volume control can be implemented either as an ac. potentiometer control or as a digital control by a µprocessor (dc. control) and that the feedback loop of the power amplifier is accessible thus making it possible to add a simple external power stage driving low impedance loud
