ATA-4000 Series High Voltage Power Amplifier

Bandwidth (-3dB) up to DC~3MHz, Output voltage up to 310Vp-p (±155Vp), Max output current 4Arms

High-voltage power amplification often needs more bandwidth than low-frequency high-voltage amplifiers provide. Aigtek's ATA-4000 Series covers this segment: high-voltage power amplifiers amplifying both AC and DC signals, with bandwidth from DC up to 500kHz, 1.2MHz or 3MHz depending on the model.

Output voltage up to 310Vp-p (±155Vp) with up to 547.1Wp of power (ATA-4052C) gives solid drive capability for high-voltage power loads, and both voltage gain and DC bias are finely adjustable, letting the output be configured precisely for the driven load. The ATA-4052C matches the ATA-400 series' ATA-402 in voltage and power, with bandwidth as the key difference: 500kHz versus 120kHz.

Within Aigtek's range, the ATA-4000 sits between the lower-bandwidth ATA-400 and the higher-power ATA-40000 (up to 1314Wp and 11.31Ap), making it a practical fit where an application needs meaningful frequency response at moderate power.

Frequently Asked Questions

How does the ATA-4000 differ from the ATA-400 series?

At the same voltage and power level the main difference is bandwidth: the ATA-4052C delivers 310Vp-p and 547.1Wp at up to 500kHz, while the ATA-402 delivers the same at up to 120kHz. Across the series, ATA-4000 models reach up to 1.2MHz (ATA-4011C, 4012C, 4014C) or 3MHz (ATA-4315), compared with up to 300kHz for the ATA-400.

What's the difference between the ATA-4000 and the ATA-40000?

The ATA-40000 is the higher-power line, with up to 1314Wp and up to 11.31Ap output current at bandwidths up to 1.2MHz. The ATA-4000 offers lower power (up to 547.1Wp) but extends to 3MHz on the ATA-4315, so the choice depends on whether the application needs more power and current or more bandwidth.

Why does fine DC bias adjustment matter for high-voltage amplification?

Many high-voltage loads — particularly capacitive or piezoelectric types — need their operating point set with a specific DC offset alongside the AC drive signal. Fine DC bias control lets that offset be tuned precisely, independent of the AC voltage gain setting.
