AMIS-14935 Audio Amplifier
Description
The AMIS-14935 (former MSC-LX1792) offers a patent pending, low-voltage, low-power and high efficiency amplifier for driving a high impedance speaker such as a hearing aid receiver or a headset. The AMIS-14935 consists of a pre-amplifier followed by a fixed gain class D amplifier. The input resistor and feedback resistor is external in the AMIS-14935 making it possible to set the gain arbitrarily, up to approximately 40dB. The feedback resistor can also be potentiometer to facilitate volume control.
