Dear sir,

I am currently designing a linear piezo actuator driver & controller for my research. However, my background is not a professional electronic field and I need help to choose a suitable CLASS D AMPLIFIER (Switching AMP) which can provide the approximate capability below:

Input voltage range: -2 to -12 V;

Output voltage range: -30 to 130V (much higher is better);

Average output current (<5ms): 1000mA;

Amplifier bandwidth: 4 kHz;

Amplifier classification: Class D (switching amp), 100 kHz (much higher is better).

I have searched the TI website for product selection and I found many of the class D amps is for Audio application so if someone can provide some advice to me is kindly appreciated.

Best regards,

ZHUANG Zhuoxuan (Damon)
