FOUNDATION® - GA3216



FOUNDATION® Digital is a flexible DSP platform which can be used to develop trimmer or programmable based hearing instruments or be used in a variety of ultra low-power audio applications. With its no-compromise design architecture, hearing instruments are guaranteed the seal of SOUNDDesign® hi-fidelity audio quality, an impressive array of parameters for an entry-level digital hybrid, low power consumption and a cost-effective price.

The GA3216 is a trimmer-configurable DSP system based on a two-channel compression circuit. It can efficiently replace traditional hearing-aid compression circuits without compromising fundamental performance requirements.
