CS8115 No noise, ultra-low EMI, 3.3W, mono, no filter required, Class D audio power amplifier
Features
• CS8115 is a high-efficiency, distortion-free, ultra-low EMI, filter-free, 3.3W mono Class D audio amplifier. The unique distortion-free function can automatically adjust the system gain by detecting the distortion of the output, which not only effectively avoids the damage to the speaker caused by high-power overload output, but also brings a comfortable listening experience.
• The fully differential architecture and extremely high PSRR of the CS8115 effectively improve the CS8115's ability to suppress RF noise. The filter-free PWM modulation structure and built-in gain reduce external components, PCB area and system cost, and simplify the design. Up to 90% efficiency, fast startup time and small package size make the CS8115 the best choice for mobile phones and other portable audio products.
• CS8115 adopts the original AERC (Adaptive Edge RateControl) technology, which can provide excellent full-bandwidth EMI suppression capability. Without any auxiliary design, it still has a margin of more than 20dB under the FCC Part15 Class B standard. It is particularly suitable for applications that are susceptible to EMI interference, such as FM, CMMB, and mobile analog TV.
• CS8115 has built-in over-current protection, short-circuit protection and over-heat protection, which effectively protects the chip from being damaged under abnormal working conditions.
• The CS8115 is available in a variety of compact packages and is rated for an operating temperature range of -40°C to 85°C.
• CS8115 is fully compatible with YDA145 (Pin to Pin Compatible)
