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
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.
The LM4917 operates from a single 1.4V to 3.6V power supply, features low 0.02% THD+N and
70dB PSRR. Independent right/left channel low-power shutdown controls provide power saving
flexibility for mono/stereo applications. Superior click and pop suppression eliminates audible
transients during start up and shutdown. Short circuit and thermal overload protection protects the
device during fault conditions.
