DESCRIPTION
The GB3211 hybrid is a programmable DSP system based
on a multi-channel 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 seperate supply line to the A/D and H-Bridge
circuits. The reflowable thinSTAX鈩?packaging enables easy
integration into BTE applications. This versatile DSP hybrid
is capable of multiple configurations and has a wide range
of functions.
The GB3211 hybrid code programmed into the GC5051
controller chip is 鈥?鈥?
