Overview
The HV254FG-G is a 32-channel high voltage amplifier array integrated circuit manufactured by Microchip Technology. It operates on a 275V high voltage supply and dual low voltage supplies of +5.0V and -5.0V. Each channel features an independent input and output with a fixed internal closed-loop gain of 50V/V (34.0dB). The device provides an output voltage swing from 7.0V to 250V, utilizing high-value internal feedback resistors to minimize current consumption. An integrated silicon diode allows for die temperature monitoring.
Feature Summary
- Integrates 32 independent high voltage amplifiers within a single array
- Features a fixed internal gain of 50V/V with high-value feedback resistors
- Includes an integrated silicon diode for die temperature sensing
- Designed for minimal power consumption while maintaining guaranteed slew rates
Applications
- MEMS driver applications
- Piezoelectric transducer driving
- Optical crosspoint switches using MEMS technology
Procurement Notes
Verify the component origin as Supertex Inc., now part of Microchip Technology. Confirm the package option is the 100-Lead MQFP. Ensure the ordering suffix matches the lead-free RoHS compliant designation. Check for specific power-up/down sequence requirements involving external protection diodes to prevent damage during operation.
Selection Notes
Select this component when designing circuits requiring multiple high voltage outputs from a single IC. It is suitable for systems needing a fixed gain of 50V/V without external resistor networks. Consider the 275V supply requirement and the non-ground-referenced output swing range. Verify that the application can accommodate the specific thermal resistance and operating temperature limits defined in the datasheet.
Part Context
This device belongs to the HV254 series of high voltage amplifier arrays. It was originally developed by Supertex Inc. before being acquired by Microchip Technology. The product line focuses on providing multi-channel solutions for driving capacitive loads typical in microelectromechanical systems and optical switching architectures.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation.
