Overview
The LA2805, 2805M is a telephone answering machine-
use bipolar IC that performs the basic functions required
for telephone answering machine and has the microcom-
puter interfaces and analog switches to control these func-
tions.
The LA2805, 2805M is applicable to telephone answering
machines of both 2-mechanism and 1-mechanism types and
available in compact DIP-24S and MFP-24D package.
Functions
1) Preamp for recording/playback (with ALC).
2) Recording amp (DC bias).
3) Analog switches.
4) Voice detector (VOX).
5) Zero-cross comparator for beep tone detection.
6) Power amp (Po=300mW, RL=8, VCC=9V).
7) Line amp.
8) Microcomputer interface.
Features
Since the LA2805, 2805M containes all the functions
required for telephone answering machine and can be
controlled by a microcomputer, a unique system can be
made up.
The recording amp gain and recording bias current can
be set independently by an external resistor.
Low distortion.
Compact package (DIP24S, MFP24D).
