In practical application, both voltage amplifier​ and charge amplifier should be equipped with overload amplification protection circuit, otherwise, the output voltage will be too high when the sensor is overloaded.

ATA-4000 series power amplifiers have been widely recognized by the industry in testing and measurement experiments, especially in transducer driving, piezoelectric ceramic driving, PZT material directional micro-transducer testing, and mems testing.

Power amplifiers are also widely used in MEMS testing, piezoelectric ceramic drives, transducer drives, non-destructive testing, particle sorting, ultrasonic testing, etc., to meet the needs of different researchers.
