Microsemi

.COM

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鈥檚 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.

Low Operating Current: 120碌A(chǔ)

Typical

Low Operating Voltage: 0.9V
