NCP2809: Audio Power Amplifier, Stereo Headphone 135 mW

Description: The NCP2809 is a cost-effective stereo audio power...
  • The NCP2809 is a cost-effective stereo audio power amplifier capable of delivering 135mW of continuous average power per channel into 16Ω loads.
    The NCP2809 audio power amplifier is specifically designed to provide high quality output power from low supply voltage, requiring very few external components. Since NCP2809 does not require bootstrap capacitors or snubber networks, it is optimally suited for low-power portable systems. NCP2809A has an internal gain of 0 dB while specific external gain can be set with NCP2809B.
    If the application allows it, the virtual ground provided by the device can be connected to the middle point of the headset. In such case, the two external heavy coupling capacitors typically used can be removed. Otherwise, you can also both outputs in single ended mode with external coupling capacitors.
    Due to its excellent PSRR, it can be directly connected to the battery, saving the use of an LDO.
  • Features
  • 135mW to a 16 load from a 5.0V power supply - Suitable for stereo headphones for portbale audio player
  • Excellent PSRR (85dB Typical) - Eliminate the need of LDO at input; can direct connect to battery
  • Pop & Click noise protection circuit - No audible noise to be heard by user
  • Ultra Low Current Shutdown Mode - Extend battery life
  • 2.2V - 5.5V Operation - Covers the range of single Lithium-based battery or 3 x Alkaline battery cell operation
  • Superior THD+N: Less than 0.01% - High sound quality
  • External Turn-on and Turn-off configuration capability - Flexible operation
  • Ultra Thin MicroDFN-10 (3x3x0.55mm) - Ultra thin and small package can fit in any space constraint design
