HV265-I/QE

Overview

The HV265-I/QE is a four-channel high-voltage operational amplifier array manufactured by Microchip Technology. It operates on a 225V high-voltage supply (VPP) and a 5V low-voltage supply (VDD). The device features an optional internal feedback resistor network that sets the closed-loop gain to 82 V/V. Each channel provides independent input and output ports, accepting an input voltage range of 0.05V to 2.5V. The output can drive capacitive loads up to 200 pF with an output impedance of less than 1 kΩ. Key electrical specifications include a maximum output voltage of +205V, a minimum slew rate of 0.02 V/µs, and a settling time of less than 10 ms. The component is housed in a 24-lead TSSOP package.
