XPT9971

Features

Product Name: Class AB/D Audio Amplifier

Product model: XPT9971

Product Description:

XPT9971 is a FM interference-free, class AB/class D selectable power amplifier. When the working voltage is 5V, the maximum driving power is 6W (2Ω, ?BTL load, THD<10%), and the total harmonic distortion noise in the audio range is less than 1%.

The application circuit of XPT9971 is simple, requiring only a few peripheral components and integrated feedback resistors; the output of XPT9971 does not require external coupling capacitors or boost capacitors and buffer networks. XPT9971 is available in MSOP, SOP, and DFN packages, and is particularly suitable for portable systems with low volume and small weight.

XPT9971 can enter sleep mode through control, thus reducing power consumption; XPT9971 has an internal overheating automatic shutdown protection mechanism. XPT9971 works stably, with a gain bandwidth product of up to 2.5MHz and stable unity gain. The voltage gain of the amplifier can be adjusted by configuring external resistors, which is convenient for application.
