Speakerphone Circuit

DATA SHEET

AS2523, AS2524, AS2524B

Key Features

General Description

Line/Speakerphone circuit on a 28-pin CMOS-IC, simple

inventory: same die for AS2523/24 and AS2523/24B

Serial I/F on AS2523, parallel I/F on AS2524

Enhanced voice switching

AS2523/24 is a CMOS integrated circuit that incorporates

DC and AC line adaptation (DC-mask and synthesized AC-

impedance of 1000Ω) as well as a speech circuit with

softclipping, line loss compensation and Rx-volume control

for handset and handsfree operation. It shall act as an a/b-

line powered device, which is controlled by a CPU via a

serial interface on AS2523 or a standard dialler via a

parallel interface on AS2524 and AS2524B.

Background noise monitoring

Tx- and Rx-gain programmable on AS2523 only

Digital volume control of Rx signals on AS2523 only

DC characteristic programmable on AS2523 only

Dual softclipping in handset mode on AS2523 only

Dual softclipping in handsfree mode on AS2523 only

Loudspeaker amplifier for loudhearing and handsfree

Supply voltage generation for external circuitry

Automatic line loss compensation on AS2523 / 24B only

Real and complex impedance selectable by external

components

Applications

Enhanced handsfree feature phones with CallerID and

extended displays. The AS2524 and AS2524B are

developed to interface with common Taiwanese dialers.

Side tone adaptation selectable by external components

Unique EMC performance

Package

Available in 28-pin SOIC or die

Operating range from 15mA to 100mA (down to 5mA

with reduced performance)

Few external components
