HVA1260

Overview

The HVA1260 is a miniature, bi-polar, zero-crossing high voltage amplifier manufactured by HVM Technology, Inc. It produces an output voltage ranging from 0 to ±6000V in response to a 0 to 5V programming input. The device operates from a 12VDC input supply and features current sourcing and sinking capabilities with a maximum output current of 100µA. It includes an active-low enable pin and offers excellent load and line regulation.

Feature Summary

• Bi-polar zero-crossing high voltage generation
• Integrated dual polarity generator and amplifier
• Proprietary ultra-compact resonant converter design
• Active low logic controlled enable input

Applications

• Mass spectrometry
• Electrostatic chucks
• Pockel cells
• Electron microscopes

Procurement Notes

Verify the specific model suffix against the manufacturer's selection guide to confirm the exact output voltage rating (±1kV, ±3kV, or ±6kV) and input voltage requirement (5V or 12V). Ensure the application environment remains within the specified operating temperature range of -40°C to +60°C. Confirm that the load capacitance does not exceed specifications to maintain rise/fall time performance.

Selection Notes

Select the HVA1260 when a ±6000V output is required with a 12VDC system power supply. This model provides a proportional response to a 0-5V control signal. Consider the HVA0560 if the system architecture utilizes a 5VDC input instead. Evaluate the load capacitance requirements, as higher capacitance significantly impacts the rise and fall times of the output voltage transition.

Part Context

The HVA Series consists of encapsulated high voltage amplifiers designed for space-constrained applications. These modules integrate a high-speed amplifier and a high-voltage generator into a single thermoset plastic package. The series supports various output voltages and input configurations to accommodate different electronic system architectures.

FAQ

How does the enable pin function?

The enable pin is logic-controlled and active low. Applying a logic low signal enables the internal high voltage generator.

What is the relationship between the programming voltage and output?

The output voltage is proportional to the programming voltage. A 0 to 5V programming input produces a negative full scale to positive full scale output.
