Analog Devices Inc. AD8210WYRZ-R7

Overview

AD8210WYRZ-R7 from Analog Devices is a high-voltage, current-sense amplifier with fixed +20 V/V gain, designed for unidirectional or bidirectional high-side current monitoring in automotive and industrial power systems. It operates from 4.5 V to 5.5 V supply, supports common-mode input voltages up to +65 V, delivers rail-to-rail output swing, and features ±200 µV input offset voltage at +25°C.

For engineers reviewing the AD8210WYRZ-R7 datasheet, AD8210WYRZ-R7 pinout, AD8210WYRZ-R7 application, or AD8210WYRZ-R7 equivalent, key selection criteria include its 65 V common-mode range, 200 kHz bandwidth, −40°C to +125°C AEC-Q100 qualified operation, and dual reference inputs enabling flexible output offset configuration for motor control and battery protection circuits.

Technical Context

The AD8210WYRZ-R7 integrates a precision current-sense amplifier with internal matched resistors and a high-voltage input stage capable of rejecting fast common-mode transients. Its differential input architecture enables accurate shunt-based current measurement without ground-loop interference, while the dual VREF1/VREF2 pins allow programmable output offset from GND to VS.

It supports three operational modes: ground-referenced output (both VREF pins tied to GND), V+-referenced output (both VREF pins tied to VS), and bidirectional mode (asymmetric offset via independent VREF biasing). The device uses a proprietary high-side sensing topology that avoids the need for level-shifting circuitry or isolated supplies.

FAQ

What is the maximum common-mode input voltage supported by the AD8210WYRZ-R7?

The AD8210WYRZ-R7 supports a maximum common-mode input voltage of +65 V, enabling direct connection to high-side shunts in 48 V battery systems and industrial 60 V DC buses. This rating is specified across the full −40°C to +125°C operating temperature range and is validated per AEC-Q100 stress testing protocols. The AD8210WYRZ-R7 maintains stable gain and offset performance even during fast common-mode transients up to 100 V/µs.

Does the AD8210WYRZ-R7 require external gain-setting resistors?

No, the AD8210WYRZ-R7 features an internally trimmed fixed gain of +20 V/V and does not require external resistors for gain configuration. Its precision laser-trimmed thin-film resistors ensure initial gain error ≤±0.5% and gain drift <5 ppm/°C. This eliminates layout sensitivity, reduces component count, and guarantees repeatable scaling from shunt voltage to output voltage without calibration-critical for production-line test efficiency in AD8210WYRZ-R7 deployments.

How is bidirectional current sensing implemented using the AD8210WYRZ-R7?

Bidirectional current sensing with the AD8210WYRZ-R7 is achieved by applying a mid-supply bias (e.g., 2.5 V) to both VREF1 and VREF2 pins, setting the output quiescent voltage to half-scale. Positive shunt current drives output above this point; negative current pulls it below. The AD8210WYRZ-R7's rail-to-rail output and matched input stage enable true symmetrical ±125 mV differential input range, delivering linear ±2.5 V output swing with <0.1% nonlinearity across temperature.

Is the AD8210WYRZ-R7 qualified for automotive applications?

Yes, the AD8210WYRZ-R7 is AEC-Q100 qualified to Grade 1 (−40°C to +125°C ambient), with full qualification including HTOL, TC, UHAST, and ESD testing per automotive reliability standards. It is manufactured in an IATF 16949-certified facility and shipped with PPAP documentation. The AD8210WYRZ-R7 is widely deployed in production automotive systems including EPS, BMS, and transmission control modules.

What is the typical supply current consumption of the AD8210WYRZ-R7?

The AD8210WYRZ-R7 draws a typical supply current of 4.5 mA at +25°C and 5 V supply, increasing to ≤5.5 mA across the full −40°C to +125°C temperature range. This low quiescent current enables integration into always-on vehicle subsystems without compromising battery standby life. The AD8210WYRZ-R7 maintains stable performance with supply ripple up to 100 mVpp, eliminating need for additional LDO filtering in noisy automotive environments.
