High Voltage Isolation Amplifier

Price Adjustment Notice
Due to rising costs in raw materials, manufacturing, and operations, ATI will increase the price of all AD202 series products by $10, effective January 1, 2026. The new prices will be reflected on our website and sales platforms.
Thank you for your understanding.

Precision Signal Detection and Isolation for High-Voltage Applications
High-voltage isolation amplifiers play a critical role in detecting small voltage signals superimposed on high AC or DC voltages, typically exceeding 1000V. These amplifiers accurately isolate, amplify, and scale down the detected signals to a low common voltage level, enabling safe and precise signal processing.

Key Applications
The primary use of isolation amplifiers is in current measurement across current-sensing resistors positioned on high-voltage rails, such as:

• AC power grids
• Electric vehicle powertrain battery banks

Introducing the AD202ATI – A High-Performance Upgrade
Analog Technologies, Inc. has developed a comprehensive series of high-voltage isolation amplifiers, among which the AD202ATI stands out as an enhanced, pin-to-pin compatible upgrade to the AD202.

Major Improvements Over AD202:

• Exceptional Accuracy: ±0.005% (compared to AD202's ±0.025%)
• Expanded Bandwidth: 20kHz (4× higher than AD202's 5kHz)
• Cost-Effective Solution: Enhanced performance at a lower price

Additional Features:

• Available in Two Package Types: SIP and DIP
• Fully Encapsulated with Epoxy for durability and environmental protection

The AD202ATI delivers unmatched precision and efficiency, making it an optimal choice for high-voltage current sensing and signal isolation applications.
