ZC8809 (esop-8) has built-in inductive charge pump boost 5W anti breaking mono audio power amplifier IC

Time:2022-05-06 Views:2193
    With the popularity of Bluetooth speakers and the improvement of users‘ requirements for sound quality and power, the mainstream audio power amplifiers in the market, such as 8002/8871/2018/ 5128, have been difficult to meet the requirements. Now, the built-in boost power amplifier launched by some domestic chip manufacturers is difficult to become the mainstream because of the price and cost. Shenzhen siyuante Technology Co., Ltd. is now vigorously promoting an esop-8 built-in non inductive charge pump boost 5W anti broken sound low-cost mono audio power amplifier ic-ZC8809. The esop-8 has a small package. The single charge pump architecture boost peripheral does not need inductance. The BOM cost of the overall PCBA of the speaker increases by about a few cents, and the power increases by two times, accelerating the popularization and application of the built-in boost power amplifier IC.

ZC8809 overview:
    
ZC8809 It is an AB / D switching audio power amplifier with automatic gain control function, based on charge pump boost technology and power up to 5.4w.
    ZC8809 The built-in unique adaptive boost function automatically selects VDD power supply or charge pump boost rectifier power supply according to the output power, which greatly prolongs the playing time of the battery.

ZC8809 characteristic:
Class AB and class D switching functions
4 anti breaking sound options
Adaptive boost function, charge_ Pump boost to 6.4v
Class D output power:
    -5. 4 W (VDD=4.5V, RL =4Ω,NCN OFF THD+N=10%)
    -5. 2 W (VDD=4.2V, RL =4Ω,NCN OFF THD+N=10%)
Class AB output power:
    -2W (VDD=4.2V, RL =4Ω,升壓關(guān)閉 THD+N=10% )
Working voltage: 2.8V to 5.5V
