Description: Piezo Microactuator Driver with Boost Regulator

Features

* Amplifier s Current Limit: ± 40mA Typical s Input Common Mode Range: 0V to 10V s Output Voltage Range: 1V to (V CC
* 1V) s Differential Gain Stage with High Impedance Output (gm Stage) s Quiescent Current (from V ): 2mA CC s Unloaded Gain: 30,000 Typical Switching Regulator Generates VCC Up

Applications

* where negative phase contributions below crossover frequency must be minimized, a phase boost capacitor can be added, as shown in Figure 4. Larger values of CBOOST will further reduce the closed-loop negative phase contribution, however, the amplifier phase margin will be reduced. For an amplifier p
