Application Scenarios & Design Considerations

1.25-W Mono, Fully Differential, Class-AB Audio Amplifier 8-MSOP-PowerPAD -40 to 85

Alternative Part Number

  • LM4990MM --: Similar 1.5W mono class-AB audio amplifier in an MSOP package, pin-compatible enough for many designs and from the same vendor.
  • MAX9716EUA --: 1.4W mono audio amplifier with similar supply range and gain configuration, suitable drop-in for low-power speaker applications.
  • PAM8302AAS --: 2.5W class-D mono audio amplifier offering higher efficiency and a different series, usable as a functional upgrade with minor layout changes.
  • MAX9710EUA --: 1.4W Class AB audio amplifier in 8-pin package offering similar output power and low-distortion performance for portable audio applications.
  • NCP2890DMR2 --: 1.2W audio power amplifier in Micro8 package with comparable gain and supply voltage, usable as a functional substitute where slight power reduction is acceptable.
