ATA-P Series Power Amplifier

Single-channel power amplifier for amplifying AC/DC signals, drives piezoelectric actuators such as PZT, stacked PZT and nano-positioning stages.

Piezoelectric actuators — PZT stacks, stacked-type PZT, open-loop packaged PZT, and nano-positioning tables — need a drive signal that can source and sink current cleanly at the voltage and current levels these devices actually demand, which is a different requirement from general-purpose signal amplification. Aigtek's ATA-P Series is built specifically as a single-channel power amplifier for this application, amplifying AC/DC signals to drive piezoelectric actuators and positioning products.

Maximum output voltage spans -20V to 150V with up to 10Ap output current and 1300Wp of power, giving the ATA-P enough voltage swing and current capability to drive the range of PZT device types it's built for — from simple PZT elements through to more demanding stacked and nano-positioning table applications. Bandwidth to 20kHz (-3dB) supports the dynamic response these positioning and actuation applications typically require.

Because piezoelectric devices present a capacitive rather than purely resistive load, driving them well requires an amplifier genuinely designed for this load type rather than a general power amplifier applied to a task it wasn't specified for — the ATA-P's naming of specific PZT product types as target applications reflects that design intent directly.

Frequently Asked Questions

Why do piezoelectric actuators need a dedicated drive amplifier rather than a general power amplifier?

Piezoelectric devices present a largely capacitive load rather than resistive, and driving them accurately — particularly at the higher voltages some PZT stacks require — benefits from an amplifier specifically designed to handle that reactive load characteristic and voltage range, which the ATA-P's PZT-focused design addresses directly.

What types of piezoelectric devices does the ATA-P support?

The series is built to drive PZT elements, stacked-type PZT, open-loop packaged PZT, and nano-positioning tables — covering a range from simpler piezoelectric actuator types through to more precision-oriented positioning applications.

What voltage and current range does the ATA-P cover?

Output voltage spans -20V to 150V with up to 10Ap current and 1300Wp power, sized to cover the voltage and current demands of the PZT device types the series is designed to drive.
