Features of functionLAG668B IC contains two high fidelity pre-amplifier and power amplifier within subwoofer excitation circuit and motor circuit with steady speed. The IC is not combined input capacitor and output coupled capacitor. The block diagram of the circuit and typical application circuit is shown as the circuit. Main electrical parameters The main parameters of LAG668B IC are following:Supply voltage range: 2.3 -4 ยท 5V, the typical operating voltage is 3V, limit 1 is used as the voltage with 7V.Static current: it is about 18nA. Dynamic operating current: the maximum is 400mA. Because of its large internal resistance, low current, you can get a wide dynamic range both in the case of low and high volume, and the sound quality is good. Power: flat package type is 450mW; dual in-line is 750mW.
The typical application circuit and internal block diagram of LAG668B IC is shown as the chart.
