Overview
The HV56264T-E/QEX-VAO is a high-voltage operational amplifier manufactured by Microchip Technology. It features four independent channels housed in a TSSOP-24 surface-mount package. The device operates within a power supply voltage range of 50 V to 225 V, with a maximum rating of 225 V and a minimum of 50 V. It exhibits a slew rate of 11 V/us and draws a typical operating supply current of 6.6 mA. Designed for automotive reliability, it holds AEC-Q100 qualification and functions reliably across an extended temperature range starting from -40 C.
Feature Summary
- Four-channel architecture providing multiple independent amplification paths within a single integrated circuit
- High-voltage capability supporting operation up to 225 V for demanding industrial applications
- Automotive-grade qualification ensuring compliance with rigorous reliability standards
- Surface-mount TSSOP-24 packaging facilitating automated assembly and compact board design
Applications
- Automotive sensor signal conditioning circuits
- Industrial process control systems requiring high voltage isolation
- Medical equipment power stage drivers
- High-voltage data acquisition front ends
Procurement Notes
Verify the specific suffix VAO against the manufacturer's latest documentation to confirm automotive grade status and RoHS compliance. Ensure the ordering quantity meets the manufacturer's standard packing requirements. Confirm that the TSSOP-24 footprint matches your PCB layout constraints before finalizing procurement. Cross-reference the datasheet revision date to ensure compatibility with your design specifications.
Selection Notes
Select this component when designing circuits requiring multiple high-voltage amplification stages in a compact form factor. The 11 V/us slew rate suits moderate-speed signal processing tasks. Verify that the system power supply can maintain the required 50 V minimum while staying below the 225 V absolute maximum rating. Consider thermal management strategies given the 6.6 mA quiescent current per channel in enclosed environments.
Part Context
This part belongs to Microchip's high-voltage amplifier portfolio, specifically engineered for robust performance in electrically noisy environments. The HV56264 series integrates precision analog capabilities with high-voltage tolerance, bridging low-voltage digital control systems with high-voltage actuator or sensor interfaces. Its automotive qualification aligns with industry demands for long-term reliability in vehicle electronics.
Replacement Considerations
Direct pin-to-pin replacements are limited due to the specific high-voltage and channel count combination. Evaluate alternative Microchip high-voltage op-amps such as the HV56263 if fewer channels suffice. Verify that any substitute maintains the 225 V maximum supply rating and AEC-Q100 certification if automotive use is required.
