Amplifiers

BTL audio amplifier1 W typicalVSSOP-82.2 V to 5.5 VThermal shutdown

LM4890MM/NOPB is a compact mono BTL audio amplifier for low-voltage portable designs, capable of 1 W typical into 8 Ω from a 5 V supply.

Best for

  • Low-voltage mono speaker outputs
  • Portable electronic equipment
  • Applications using an 8 Ω BTL load

Avoid if

  • A grounded single-ended speaker output is required
  • The supply cannot provide adequate headroom for the required audio power
  • PCB thermal dissipation cannot be verified

Check before use

  • Validate THD at the required output level and supply voltage
  • Place supply and bypass capacitors close to the device
  • Check junction temperature using the package derating guidance
