DESCRIPTION
The GA3214 (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 GA3214 hybrid contains the GC5051 controller chip
and the GA3224 hybrid contains the GC5057 controller
chip. The only difference between the GC5051 and the
GC5057 is in their Power On Reset (POR) behaviour.
For a detailed description of the POR behaviour of the
GC5051 and GC5057 controller chips, please refer to
