Supertex inc. HV264 Quad, High Voltage, Amplifier Array Features General Description Applications When both VOUT and FB pins are connected together and RGND is set at 0V, a non-inverting amplifier is formed with closed loop gain of 66.7V/V. High value internal feedback resistors are used to minimize the power dissipation. The input voltage VIN is designed for a range of 0.05V to 2.85V. The output can swing from 1.0V to VPP -10V. A 2.85V input will cause the output to swing to 190V. ►► ►► ►► ►► ►► ►► ►► ►► ►► ►► ►► Four independent high voltage amplifiers 190V output swing 9.0V/µs typical output slew rate Fixed gain of 66.7V/V High value internal feedback resistors Very low operating current The Supertex HV264 is a quad high voltage amplifier array integrated circuit. It operates on a 200V high voltage supply and a 5.0V low voltage supply. Each channel has its own input and output. Tunable Laser MEMS driver Test equipment Piezoelectric transducer driver Braille driver The HV264 is designed for maximum performance with minimal high voltage current. The high voltage current for each channel is less than 75µA. The typical output slew rate performance is 9.0V/µs.

To prevent damage, please follow the acceptable power up / down sequences and add an external diode across VPP and VDD, where the anode of the diode is connected to VDD and the cathode is connected to VPP. Any low current high voltage diode such as a 1N4004 will be adequate.
