AI Technical Summary
Technical Problem
In electronic devices, as the number of speaker channels increases, the number of power amplifiers also increases, resulting in excessively large board area, which limits the promotion of multi-channel systems.
Method used
By setting at least two bare chips in the power amplifier chip, each bare chip having a power amplifier circuit, and encapsulating them as a single chip through a connection layer and pads, at least two power amplifiers are formed, reducing the area occupied by the board layout.
Benefits of technology
This effectively reduces the packaging cost and peripheral circuit components of the power amplifier, lowers development time, costs, and risks, and saves board space.
