Preliminary Data Sheet

AS2507

Single Chip 2-Wire Intercom

CMOS Integrated Circuit

Austria Mikro Systeme International AG

Key Features

General Description

Line/speech circuit and signalling on one 14

pin CMOS chip

The AS2507 is a CMOS integrated circuit that

contains all the functions needed to build a 2-

wire intercom network.

Only 2 wires needed for power supply,

signalling and speech

The device incorporates 2/4-wire conversion

(hybrid), soft clipping for high speech quality,

FSK modem and a simple interface to a

microcontroller.

Soft clipping to avoid harsh distortion

Fully integrated 2/4 wire conversion

Side tone cancellation

The signalling mode is selectable between

FSK modulation and burst mode.

Low noise

Signalling with FSK modem

The low standby current (typ. 2 mA) allows

several devices to listen to the 2-wire line.

Low standby power consumption allows

parallel operation of up to 25 terminals on a

bus pair with central supply

The speech circuit is designed for compatibility

with commonly used handset (150Ω earpiece

and electret microphone) with receive gain of

-6 dB and transmit gain of 32 dB (relative to

line).

Parallel operation of up to 70 terminals if

supplied locally

Controllable via simple µC interface

Very few external components

Package

Application

Available in 14 pin DIP and 16 pin SOIC

Entrance telephone system, intercom and data

transmission, alarm systems, toy phone
