Datasheet Details

Part number:

LM4922

Manufacturer:

National Semiconductor

File Size:

1.24 MB

Description:

80mW Stereo Headphone Amplifier

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

Applications

* Boomer audio power amplifiers were designed specifically to provide high quality output power with a minimal amount of external components. The LM4922 does not require output coupling capacitors or bootstrap capacitors, and therefore is ideally suited for mobile phone and other low voltage applicat
