LM4926 Datasheet Ground-referenced And Ultra Low Noise - Fixed Gain - 80mw Stereo Headphone Amplifier

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: June 2005 .. LM4926 Ground-Referenced, Ultra Low Noise, Fixed Gain, 80mW Stereo Headphone Amplifier LM4926 Ground-Referenced, Ultra Low Noise, Fixed Gain, 80mW Stereo Headphone.

General Description

The LM4926 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 LM4926

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 eliminating output-coupling capacitors typically used with normal single-ended loads. The LM4926 features an Automatic Standby Mode circuitry (patent pending). In the absence of an input signal, after approximately 12 seconds, the LM4926 goes into low current standby mode. The LM4926 recovers into full power operating mode immediately after a s.
