Versatile integrated industrial piezo driver deals with both low- and high-voltage loads

Mouser now stocks the Texas Instruments (TI) DRV2700 industrial piezo driver - a single-chip device with an integrated 105V boost switch, integrated power diode, and integrated fully-differential amplifier. The 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 DRV2700 supports four GPIO-controlled gains: 28.8dB, 34.8dB, 38.4dB, and 40.7dB. 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 DRV2700 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. Applications include positioning actuators, sounder drivers, inkjet printers, transducers and micro-pumps.
