WT85711 Class AB power amplifier IC chip

Published: two thousand and twenty-one - 08 - 09

WT85711 is a 5.0W mono audio amplifier with FM interference free and Class AB power amplifier and Class D power amplifier switchable modes. Under 5V power supply, it can provide 5.0W output power to 2 Ω load, and has an efficiency of up to 90%; The WT85711 adopts AERC (Adaptive Edge Ratecontro1) technology, which greatly reduces EMI interference in the full audio bandwidth. For a 60cm audio cable, it has more than 20dB margin under the FCC standard. The PWM modulation structure of WT85711 without filter in Class D mode reduces the number of external components, PCB area and system cost, and simplifies the design. The chip has built-in overcurrent protection, overheat protection and undervoltage protection functions, which ensure that the chip can be turned off under abnormal working conditions, effectively protecting the chip from being damaged. When the abnormal conditions are eliminated, WT85711 has a self recovery function to enable the chip to work again. The switching mode of the output transistor determines the high efficiency of the WT85711D amplifier. In Class D mode, the output transistor is like a current adjustment switch, and the extra power consumed in the switching process is negligible. The power loss related to the output stage is mainly the I2R generated by the MOSFET on resistance and the power supply current. The efficiency of WT85711 can reach 90% without filter, Class D mode of WT85711 adopts PWM modulation mode without filter, which eliminates the LC filter of traditional Class D amplifier, improves efficiency, and provides a smaller area and lower cost implementation scheme for the audio subsystem of portable equipment Pop&Click: suppresses the built-in proprietary timing control circuit of WT85711, realizes comprehensive Pop&Click suppression, and can effectively eliminate the system at the power on point, Transient noise that may occur during Wakeup and Shutdown operations. During the application of the protection circuit WT85711, when the chip has a short circuit between the output pin and the power or ground, or a short circuit fault between the outputs, the overcurrent protection circuit will turn off the chip to prevent the chip from being damaged. After the short circuit fault is eliminated, WT85711 automatically resumes operation. When the chip temperature is too high, the chip will also be turned off. After the temperature drops, WT85711 can continue to work normally. When powered

WTN5 voice chip

It is better to choose double head or three head or even four head rotary shaver. For men with allergic skin, the choice of shaver is as cautious as that of cosmetics for women. Industry insiders said that nickel is the most common allergen. When skin is damaged, bacterial infection and excessive friction can increase the absorption of nickel. Therefore, although some electric shavers can play the role of vibrating massage, unblocking the meridians and blood, and enhancing the vitality of the area around the lips and cheeks, the skin near the mouth will itch for a while after use by a few men, This may be related to contact with nickel contained in electric shavers.

WTN3 voice chip

The forward radiated sound waves of the loudspeaker are superposed in the same phase, which can provide a wider bandwidth than the enclosed type, with higher sensitivity and less distortion. Ideally, the lower limit of the low-frequency playback frequency can be as much as 20% lower than the speaker resonance frequency. This kind of speaker can reproduce rich bass with a smaller box, which is the most widely used type.
