SX8750 30V DAC for piezo actuator control WIRELESS & SENSING Vsupply Vdig VDD Charge pump Power management 100 nF VSS SCL VHV VAFP DDAC SDA 35V tank 100 nF I2C I2C DATASHEET Preliminary Actuator Shutdown Control Logic XSD VAFN SX8750 General Description Key Product Features SX8750 is a piezo actuator driver. It operates from a 3V supply and generates up to 30V to drive the actuator. No coil or external flying capacitor is used to increase the voltage, minimizing the number of externals and the size of the solution. The differential output drives the actuator with positive or negative voltage. Applications Capacitive actuator control Piezoelectric actuator control I2C controlled 10 bit differential DAC Wide supply range: 2.4 - 4.8 V supply voltage Wide output range: -16 V to +30 V differential output. No coil, no external flying capacitor Extremely lowpower down to 1 mA active, 1 uA shutdown Programmable slew rate limitation Up to 10 kS/s Small CSP footprint: 0.8 x 1.6 mm2 Ordering Information 20120628 ©2011-2012 Semtech Corp.
