General Description
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.
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.
