ATA-2000 Series High Voltage Amplifier

Bandwidth (-3dB) DC~1MHz, Output voltage up to 1600Vp-p (±800Vp), Max output current 500mAp (higher current customizable)

Some high-voltage drive applications need more than a single output channel — differential drive configurations, where two synchronised outputs work together to double the effective voltage swing across a load, are a standard technique in high-voltage piezoelectric and actuator drive applications. Aigtek's ATA-2000 Series is built specifically for this: a high-voltage amplifier with dual-channel output that can be adjusted synchronously, delivering a maximum differential output of 1600Vp-p (±800Vp).

The synchronous dual-channel architecture means both output channels track together as a matched pair, which matters for differential drive applications where any mismatch between the two channels would introduce unwanted common-mode signal or reduce the effective differential swing actually reaching the load. This makes the ATA-2000 particularly suited to applications specifically designed around differential high-voltage drive, rather than single-ended high-voltage output.

Where a load or actuator is configured to accept differential drive — splitting the voltage swing symmetrically across two connections rather than referencing one output to a common ground — the ATA-2000's dual-channel synchronous output provides that configuration directly, rather than requiring two separate single-ended amplifiers manually synchronised.

ATA-2021B High Voltage Amplifier: Introduction, Full Specifications & Datasheet
Product Introduction

The ATA-2021B is a single-channel high-voltage amplifier capable of amplifying both AC and DC signals. The maximum output voltage is 200Vp-p, with the output voltage range adjustable according to the output rail. The DC bias voltage can be adjusted in three levels, with continuous variation allowing a maximum output of ±160V, enabling the generation of asymmetric signals to drive high-voltage loads. Input and output impedance can be switched between two levels, voltage gain is digitally adjustable with parameters saved automatically, and program control is supported. The wide-range power supply accommodates different regional power standards.

Frequently Asked Questions

What's the advantage of differential output over single-ended high-voltage output?

A differential configuration splits the voltage swing across two matched output channels rather than referencing the full swing to ground from a single output, which can improve noise rejection and, for loads specifically configured to accept differential drive, deliver the intended voltage swing more effectively than a single-ended equivalent.

Why does synchronous dual-channel operation matter rather than two independent channels?

If the two channels weren't synchronised, timing or gain mismatches between them could introduce unwanted signal artifacts or reduce the effective differential voltage reaching the load. Synchronous operation ensures both channels track together precisely, preserving the intended differential drive characteristic.

Is the ATA-2000 suited to single-ended applications as well?

While its dual-channel synchronous architecture is specifically built for differential drive applications, the individual channels can typically also serve single-ended use cases — though applications specifically requiring differential drive are where the ATA-2000's design advantage is most directly realised.
