General Description
AS2504 is a CMOS integrated circuit that
incorporates DC and AC line adaptation (DC-
mask and synthesised AC-impedance of
1000
) as well as a speech circuit with
softclipping, line loss compensation and Rx-
volume control. It shall act as an a/b-line
powered or auxiliarily powered device, which is
controlled by a CPU.
Application
Cordless base stations, answering machines,
a/b-line or auxiliary powered telephone sets.
Package
Available in 28 pin SOIC
