DESCRI PTION
The 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.
The core of the amplifier is built upon
Microsemi’s patented LX1790 class D
amplifier.
The LX1790 consists of a preamplifier
followed by a fixed gain class D amplifier.
The input resistor and feedback
resistor is external in the LX1792 making
it possible to set the gain arbitrarily, up to
approximately 40dB. The feedback
resistor can also be potentiometer to
facilitate volume control.
