PARAGON GB3221
Preconfigured DSP System
for Hearing Aids
Description
The Paragon GB3221 hybrid is a programmable DSP system based
on a multichannel compression circuit. This hybrid is designed for
low impedance receivers. It can be used as a platform for a wide range
of hearing aid applications. It also offers a separate supply line to the
A/D and HBridge circuits. The reflowable thinSTAX® packaging
enables easy integration into BTE applications. This versatile DSP
hybrid is capable of multiple configurations and has a wide range of
functions.
The Paragon GB3221 hybrid contains the GC5057 controller
featuring Power On Reset (POR) behavior.
The Paragon GB3221 hybrid code programmed into the GC5051
and the GC5057 controller chip is “7”.
