LM4922 Datasheet 80mw Stereo Headphone Amplifier

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: LM4922 Ground-Referenced, Ultra Low Noise, Fixed Gain, 80mW Stereo Headphone Amplifier December 2005 LM4922 Ground-Referenced, Ultra Low Noise, Fixed Gain, 80mW Stereo Headphone.

General Description

The LM4922 is a ground referenced, fixed-gain audio power amplifier capable of delivering 80mW of continuous average power into a 16Ω single-ended load with less than 1% THD+N from a 3V power supply.

The LM4922

Key Features

  • a new circuit technology that utilizes a charge pump to generate a negative reference voltage. This allows the outputs to be biased about ground, thereby elimiwww. DataSheet4U. com nating output-coupling capacitors typically used with normal single-ended loads. The LM4922 features an Automatic Standby Mode circuitry (patent pending). In the absence of an input signal, after approximately 12 seconds, the LM4922 goes into low current standby mode. The LM4922 recovers into full power operating mode i.
