Product Summary

The XPT4809MS is a class AB dual audio power amplifier. Each channel can provide 105mW of average power (5V operating voltage, 16Ω load, THD + N = 0.1%) within the audio range, total harmonic distortion + noise is less than 0.1% (20Hz to 20KHz).
Simple the XPT4809 application circuit, only a very small number of peripheral devices; XPT4809 output does not require bootstrap capacitors or snubber networks, MSOP, SOP package to save the circuit area, ideal for mobile phones and mobile devices with low voltage, low-power applications. The XPT4809MS into sleep mode by controlling, thereby reducing power consumption; XPT4809 has an internal thermal shutdown protection mechanism. XPT4809 job stability, the gain-bandwidth product of up to 2.5MHz, and unity-gain stable. The feedback resistor external gain configuration by external gain-setting resistors to facilitate their application.
