Precision Current Measurement Redefined for Industrial and Automotive Systems

Sponsored by Analog Devices

In the domain of industrial and automotive electronics, precise current measurement is crucial for the reliable operation of systems. Analog Devices steps up to meet this demand with their high-performance current-sense amplifier, the AD8410A, designed to provide accurate current measurements in tough environments. >> Learn more about AD8410A.

High Precision and Broad Temperature Performance

The AD8410A boasts an impressive initial gain of 20 V/V and features a broad bandwidth of 2.2 MHz. This allows for rapid response to current changes, essential for applications requiring quick feedback loops. Gain accuracy is critical in current-sensing applications, and the AD8410A ensures a maximum ±0.13% gain error across a wide temperature range, providing reliable performance from −40°C to +125°C.

Engineered for Stability

One of the standout characteristics of the AD8410A is its in-package trim core, which substantially minimizes offset drift to ±0.21 μV/°C. This precision is maintained over the full operating temperature and common-mode voltage range without resorting to complex techniques like chopping and autozero clocks, which could introduce unwanted noise into the system.

Versatility in Measurement

The AD8410A shines with a high DC common-mode rejection ratio (CMRR) of 123 dB from −2 V to +70 V. It excels at bidirectional current measurements across a shunt resistor, ensuring versatility in various applications. Its buffered output directly interfaces with typical converters, making it an ideal choice for a range of industrial and automotive uses.

Applications That Benefit

With its robust design, the AD8410A is well-suited for in-phase or high-side current sensing in motor control applications, including BLDC and low-inductance motors. It’s also effective in managing bidirectional 48 V to 12 V DC-DC converters, controlling solenoids, monitoring power rails, and low-side current sensing tasks. Its ability to accurately measure current in these applications ensures efficient operation and protection of critical components.

Packaging Options for Design Flexibility

Available in an 8-lead SOIC_N package and an 8-lead MSOP package, the AD8410A provides flexibility for various design needs. This, coupled with its ability to handle pulse-width modulation (PWM) type input common-mode voltages, makes the AD8410A a versatile solution that can be integrated into a plethora of electrical systems.


The AD8410A from Analog Devices represents a significant leap forward in current-sense amplifier technology, offering unparalleled precision and stability for a range of demanding applications. Its integration into automotive and industrial systems can contribute to greater efficiency, safety, and reliability.
