XS9151A
The XS9151A is packaged in SOP8 and is particularly suitable for use in portable systems with low volume and weight.
XS9151A application circuit is simple, only a few peripheral devices;
The XS9151A output does not require external coupling capacitors or up-lift capacitors and buffering networks;
The XS9151A is packaged in SOP8 and is particularly suitable for use in portable systems with low volume and weight.
The XS9151A can be controlled to enter the off mode, thus reducing power consumption;
XS9151A has an internal overheat automatic shutdown protection mechanism;
The XS9151A works stably, and the voltage gain of the amplifier can be adjusted by configuring the peripheral resistor, which is convenient for application.

XS9151A Typical application circuit:
Note: The components in the above application diagram are described:
Ci: Straight capacitance, in 0.1µF or less, further eliminates clatter-pitting and noise coupled in from the input.
Cs: Power decoupling capacitor, use a sufficiently low ESR capacitor (less than 1µF), when VDD=5V, it is recommended to add another low ESR capacitor (not less than 10µF) to better filter out low frequency noise. The closer the decoupling capacitor is to the VDD pin, the better. Keep it within 1.5mm.
CB: The BYPASS port outputs VDD/2 voltage and is grounded through a capacitor CB (1µF) to ensure stability.
