Amplifiers

stereo headphone amplifiercapacitor-less outputVSSOP-82.2 V to 5.5 Vactive-low shutdown

LM4910MM/NOPB is a capacitor-less stereo headphone amplifier for portable 2.2 V to 5.5 V audio systems, supplied in an 8-pin VSSOP package.

Best for

  • Portable stereo headphone outputs
  • Battery-powered audio equipment
  • Applications needing low external capacitor count

Avoid if

  • The output must connect directly to a grounded single-ended line input
  • External powered speakers have only single-ended inputs and turn-on transient performance is critical

Check before use

  • Confirm that the headphone sleeve is connected to VO3 rather than ground
  • Verify output power at the intended supply voltage and headphone impedance
  • Place a 0.1 µF to 1 µF supply bypass capacitor close to VDD
