The DRV2700RGPT is a single-chip Piezo Driver with an integrated 105V boost switch, integrated power diode and integrated fully-differential amplifier. This versatile device is capable of driving both high-voltage and low-voltage piezoelectric loads. The input signal can be either differential or single-ended and AC or DC coupled. The device supports four GPIO-controlled gains of 28.8/34.8/38.4/40.7dB. The boost voltage is set using two external resistors. The boost current-limit is programmable through the R(REXT) resistor. The boost converter architecture does not allow the demand on the supply current to exceed the limit set by the R(REXT) resistor which allows the user to optimize the device circuit for a given inductor based on the desired performance requirements. Additionally, this boost converter is based on a hysteretic architecture to minimize switching losses and therefore increase efficiency. Thermal overload protection prevents the device from damage when overdriven.
