Product Overview

The LM4906MM/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 1W of continuous average power to an 8R BTL load with less than 1% distortion (THD+N) from a +5V power supply. The LM4906 is the first Texas Instruments boomer power amplifier that does not require an external PSRR bypass capacitor. The LM4906 also has an internal selectable gain of either 6 or 12dB. In addition, no output coupling capacitors or bootstrap capacitors are required which makes the LM4906 ideally suited for cell phone and other low voltage portable applications. The LM4906 contains advanced pop and click circuitry that eliminates noise, which would otherwise occur during turn-on and turn-off transitions.
  • No output or PSRR bypass capacitors required
  • Improved click and pop suppression circuitry
  • Minimum external components
  • BTL output can drive capacitive loads
  • Ultralow current shutdown mode (SD low)
  • 5ms (typical) Very fast turn on time
  • 0.1µA Typical total shutdown power supply current
  • Green product and no Sb/Br

Applications

Audio, Computers & Computer Peripherals, Portable Devices, Communications & Networking
