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.

Features
. _{One-chip voice signal processing for single-mechanism}
. ^{answering machines}
Because the LA2806M incorporates all of the basic functions
required for an answering machine and can be controlled by
a microcontroller, this IC makes it possible to design an
original system
. _{Built-in power amplifier}
. _{Allows conversation recording mode}
. _{Recording bias and amplifier gain control current can be set}
. ^{separately using external resistors.}
