The ChipSourceTek-CST8110 is a high-performance audio power amplifier designed for low electromagnetic interference (EMI) applications. This chip does not require an external filter and supports Class AB/D switching modes, making it excellent in portable audio products. The features and application advantages of the chip are described in detail below.

    The ChipSourceTek-CST8110's differential input architecture and extremely high power rejection ratio (PSRR) enable it to effectively reduce RF noise interference. Its built-in PWM modulation structure without filter and gain built-in way not only reduces the number of external components, but also reduces the PCB area and system cost, making the design more concise. In addition, up to 91% efficiency, fast startup time, and compact package size make the ChipSourceTek-CST8110 particularly suitable for portable audio devices.

    In terms of output power, the ChipSourceTek-CST8110 performs particularly well. At 14.4V operating voltage, the maximum drive power can reach 25W (4Ω BTL load), and the total harmonic distortion plus noise is less than 1%. The ChipSourceTek-CST8110 delivers stable and efficient output even at low supply voltages, such as 12V or 7.4V. These features ensure excellent sound quality and reliability in different application scenarios.

    To improve system reliability, the ChipSourceTek-CST8110 integrates multiple protection features, including overcurrent protection (OCP), overtemperature protection (OTP) and undervoltage shut-off (UVLO). These functions not only extend the standby time of the system, but also enhance the stability of the overall system. In addition, POP-click suppression on and off significantly improves the listening experience and simplifies the system debugging process.

    Another important feature of the ChipSourceTek-CST8110 is its flexible working mode. Users can switch between Class AB and Class D modes according to specific needs. Class AB mode can provide higher audio fidelity, suitable for hi-fi audio equipment; Class D mode, on the other hand, is more efficient and suitable for power-sensitive applications. This flexibility allows ChipSourceTek-CST8110 to be used in a wide range of audio products.

    From an application perspective, the ChipSourceTek-CST8110 is suitable for a variety of audio devices, including but not limited to portable speakers, headphone amplifiers, and other portable devices that require high-quality audio output. Its low EMI characteristics and high performance make the chip particularly suitable for environments that are sensitive to electromagnetic interference.

    ChipSourceTek-CST8110 is a leader in the field of audio power amplifiers with its excellent performance, flexible working mode and wide application prospects. Whether from the technical parameters or practical application effect, ChipSourceTek-CST8110 has shown extraordinary strength and broad market prospects.
