PARAGON GB3225
Preconfigured DSP System
for Hearing Aids
Description
The Paragon GB3225 hybrid is a programmable DSP system based
on a multi−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
integration into BTE applications. This very versatile DSP hybrid is
capable of multiple configurations and has a wide range of functions.
The Paragon GB3225 hybrid contains the GC5057 controller chip
featuring Power On Reset (POR).
The Paragon GB3225 hybrid code programmed into the GC5057
controller chip is “9”.
