PARAGON GA3224
Preconfigured DSP System
for Hearing Aids
Description
The Paragon GA3224 hybrid is a programmable DSP system based
on a two−channel compression circuit. It can be used as a platform for
a wide range of hearing aid applications. Its extensive
programmability and compact size make it ideal for sophisticated CIC
applications. The reflowable thinSTAX® packaging enables easy use
in BTE applications. This very versatile DSP hybrid is capable of
multiple configurations and has a wide range of functions.
The Paragon GA3224 hybrid contains the GC5057 controller chip
featuring Power On Reset (POR).
The Paragon GA3224 hybrid code programmed into the GC5057
controller chip is “8”.
