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. 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. 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.
