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.
Key Features
• Low Operating Current: 120µA Typical
• Low Operating Voltage: 0.9V minimum
• Gain Set by External Resistors
Applications
• Hearing aid applications
• High impedance speaker/transducer applications
Product Highlight
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.
• 3 output switch resistance settings: 48, 24 & 16Ω
• 5µVrms Input Referred Noise
