DRV2700参考设计应用电路:

图1DRV2700内部结构图

The DRV2700 device is a single-chip piezo driver with an integrated 105-V boost switch, integrated power diode,and integrated fully-differential amplifier. This versatile device is capable of driving both high-voltage and lowvoltage piezo loads. The input signal can be either differential or single-ended. The DRV2700 device supports four GPIO-controlled gains: 28.8dB, 34.8dB, 38.4dB,and 40.7dB.
