Product Overview

The LM4990MM/NOPB is an Audio Power Amplifier primarily designed for demanding applications in mobile phones and other portable communication device applications. It is capable of delivering 1.25W of continuous average power to an 8R BTL load and 2W of continuous average power (NGZ and DGQ only) to a 4R BTL load with less than 1% distortion (THD+N+N) from a 5VDC power supply. Boomer audio power amplifiers were designed specifically to provide high quality output power with a minimal amount of external components. The LM4990 does not require output coupling capacitors or bootstrap capacitors and therefore is ideally suited for mobile phone and other low voltage applications where minimal power consumption is a primary requirement. The LM4990 features a low-power consumption shutdown mode. To facilitate this, shutdown may be enabled by either logic high or low depending on mode selection.
  • Ultralow current shutdown mode
  • Improved click and pop circuitry eliminates noise during turn-on and turn-off transitions
  • No output coupling capacitors, snubber networks or bootstrap capacitors required
  • Unity-gain stable
  • External gain configuration capability
  • User selectable shutdown high or low logic level
  • 0.1µA (typical) Shutdown current
  • 64dB PSRR
  • Green product and no Sb/Br
