CST4863 Product Overview:
CST4863 is a dual bridge stereo audio power amplifier. When inputting a working voltage of 1KHz and 5V, the maximum driving power is 3W (4 Ω load, THD+N ≤ 10%). CST4863 integrates dual bridge speaker amplification and stereo headphone amplification, with a simple application circuit that only requires a few peripheral devices to provide high-quality output power. Additionally, when driving stereo headphones, the headphone input allows the amplifier to operate in single ended mode.
CST4863 adopts two types of packaging: SOP-16 and DIP-16. It can be controlled to enter shutdown mode, thereby reducing power consumption; Internally equipped with overheat automatic shutdown protection mode; Stable work and stable unit gain; There is also a function to reduce startup noise.

CST4863 Typical application circuit:
Note: Component description in the above application diagram
Ri: Set the input resistance for closed-loop gain together with Rf, and also form a high pass filter with Ci, with fC=1/(2 π RiCi).
Ci: Input coupling capacitor, mainly used to isolate the DC voltage at the input of the operational amplifier, and also forms a high pass filter with the input resistor Ri, fC=1/(2 π RiCi).
Rf: Set the feedback resistor for closed-loop gain together with Ri.
Cs: Provide the power bypass capacitor for the power filter, refer to the "Application Information" section to set and select the appropriate bypass capacitor.
CB: Filter capacitor for VDD/2 reference voltage bypass pin, refer to the "Application Information" section to set and select the appropriate bypass capacitor
