HV264TS-G

Overview

The HV264TS-G is a quad high-voltage amplifier array integrated circuit manufactured by Microchip Technology. It operates on a 225V high-voltage supply and a 5V low-voltage supply, housed in a 24-lead TSSOP package. The device provides four independent channels with a typical output slew rate of 9V/µs and a fixed closed-loop gain of 66.7V/V. Each channel features an input voltage range of 0.05V to 3.22V and can swing from 1V to VPP–10V. High-value internal feedback resistors minimize power dissipation while maintaining very low operating current.

Feature Summary

• Integrates four independent high-voltage amplifier channels within a single compact package
• Utilizes high-value internal feedback resistors to achieve minimal power dissipation and low operating current
• Provides a fixed non-inverting closed-loop gain configuration for simplified circuit design
• Supports high-voltage operation up to 225V with a typical output slew rate of 9V/µs

Applications

• Tunable Laser systems
• Microelectromechanical Systems (MEMS) Driver circuits
• Piezoelectric Transducer Driver applications
• Braille Driver mechanisms

Procurement Notes

Verify the specific ordering suffix 'TS' confirms the 24-lead TSSOP package type and reel media format. Confirm that the 'G' suffix indicates lead-free and RoHS-compliant construction as specified in the product identification system. Ensure compatibility with the required 225V high-voltage and 5V low-voltage supply rails before finalizing procurement specifications.

Selection Notes

Select this component when a multi-channel high-voltage amplification solution is required without external discrete components. The fixed internal gain simplifies layout but limits flexibility compared to external resistor configurations. Verify that the maximum capacitive load does not exceed 15 pF to maintain stability. Ensure the application environment remains within the specified -40°C to +125°C operating temperature range.

Part Context

The HV264 belongs to Microchip's family of high-voltage amplifier arrays designed for precision control applications. It succeeds legacy designs from Supertex and Micrel, retaining functional compatibility while updating manufacturing processes. The TS suffix specifically denotes the thin shrink small outline package variant, distinguishing it from other form factors available within the broader HV264 product line.
