Monolithic Linear IC

LA2806M

Signal Processor and Power Amplifier IC for

Telephone Answering Machines

Overview

The LA2806M is a one-chip voice signal processing IC for

single-mechanism answering machines that incorporates the

basic functions required for an answering machine as well as

the microcontroller interface and analog switches that are

needed in order to control those basic functions.
