The GS3024A is a Gennum proprietary hybrid for CIC applications. It incorporates a newly designed integrated circuit which offers optimum performance in class D receiver applications.
The GS3024A system consists of a voltage regulator, a single low noise inverting preamplifier and a mid supply referenced output stage. The voltage regulator GS3024A provides a clean DC voltage for the microphone and preamplifier, so that at end of battery life conditions when the output impedance of the battery is high,the system maintains stable operation. The preamplifier and output stage GS3024A have been optimally compensated to minimize aliasing effects normally associated with class D operation.
The two stages have been DC coupled to reduce the external components required, thereby minimizing the hybrid footprint. The hybrid incorporates a decoupling capacitor for the regulator GS3024A as well as input and output coupling capacitors for the microphone and receiver. In a minimum parts configuration, a microphone, receiver and gain set resistor, need to be added to the hybrid for a fully functional hearing instrument. Should the GS3024A application require the Maximum Power Output (MPO) to be adjusted, a potentiometer can be added from pad 6 of the hybrid to ground.
