Product details

Description

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.

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 loudspeakers up to several watts. Filtering is possible of both, the audio and the speech switching control signals, in both transmitter and receiver channels.
Key Features Minimum of external.
