AD8211WYRJZ-RL

Overview

The AD8211WYRJZ-RL is a high-voltage current shunt amplifier from the Analog Devices AD8211 series, housed in a compact SOT-23-5 surface-mount package. It operates on a single supply voltage ranging from 4.5 V to 5.5 V with a quiescent current of 2 mA. The device supports a common-mode voltage range from -2 V to 65 V and features a gain-bandwidth product of 500 kHz. Key performance metrics include a common-mode rejection ratio of 120 dB, an input offset voltage of 1 mV, and a gain error of 0.25%. It is qualified for automotive applications under AEC-Q100 standards and functions within a temperature range of -40°C to +125°C.

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm the specific suffix 'W' indicates automotive qualification status. Request official datasheets and traceability documentation prior to purchase. Ensure storage conditions comply with moisture sensitivity levels defined in the manufacturing specifications.

Selection Notes

Select this component when high common-mode voltage handling is required in space-constrained designs. The SOT-23-5 package offers a small footprint suitable for dense PCB layouts. Consider the 500 kHz bandwidth for applications requiring moderate response speeds. Verify that the 65 V common-mode limit aligns with the system's maximum bus voltage.

Part Context

This part belongs to the AD8211 family of high-voltage current shunt amplifiers designed for precision measurement. The 'W' suffix denotes automotive-grade qualification, distinguishing it from standard industrial variants like the AD8211YRJZ-RL. These devices integrate precision resistors and amplifiers to provide accurate current sensing without external components.

FAQ

What does the 'W' suffix indicate in the AD8211WYRJZ-RL part number?

The 'W' suffix signifies that the device is qualified for automotive applications according to the AEC-Q100 standard.

Is the AD8211WYRJZ-RL bidirectional?

No, the AD8211 is a unidirectional current shunt amplifier. Bidirectional sensing requires different models such as the AD8210 or AD8216.
