General Description
AS2523/24 is a CMOS integrated circuit that incorporates
DC and AC line adaptation (DC-mask and synthesized AC-
impedance of 1000) 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.
Applications
Enhanced handsfree feature phones with CallerID and
extended displays. The AS2524 and AS2524B are
developed to interface with common Taiwanese dialers.
Package
Available in 28-pin SOIC or die
