LM4917 - Ground-Referenced / 95mW Stereo Headphone Amplifier

Description

The LM4917 is a stereo, output capacitor-less headphone amplifier capable of delivering 95mW of continuous average power into a 16Ω load with less than 1% THD+N from a single 3V power supply.

The LM4917 provides high quality audio reproduction with minimal external components.

Features

  • low 0.02% THD+N and 70dB PSRR. Independent right/left channel low-power shutdown controls provide power saving flexibility for mono/stereo.

LM4917 Ground-Referenced, 95mW Stereo Headphone Amplifier November 2004 LM4917 Ground-Referenced, 95mW Stereo Headphone Amplifier General Description The LM4917 is a stereo, output capacitor-less headphone amplifier capable of delivering 95mW of continuous average power into a 16Ω load with less than 1% THD+N from a single 3V power supply. The LM4917 provides high quality audio reproduction with minimal external components. A ground referenced output eliminates the output coupling capacitors typically required by single-ended loads, reducing component count, cost and board space consumption. This makes the LM4917 ideal for mobile phones and other portable equipment where board space is at a premium. Eliminating the output coupling capacitors also improves low frequency response.
