Product details
Overview
AD8210WYRZ-RL from Analog Devices is a high-voltage, high-side current sense amplifier with fixed 20 V/V gain, designed for bidirectional or unidirectional shunt-based 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 (max) at +25°C.
For engineers reviewing the AD8210WYRZ-RL datasheet, AD8210WYRZ-RL pinout, AD8210WYRZ-RL application, or AD8210WYRZ-RL equivalent, this page provides verified technical context, validated pin functions, confirmed operating modes (unidirectional/bidirectional), real-world use cases in motor control and battery management, and two field-tested alternative parts with documented functional differences.
Technical Context
The AD8210WYRZ-RL integrates a precision current-sense amplifier with internal matched resistors and a high-voltage input stage enabling direct connection to high-side shunts. Its architecture supports configurable output referencing via VREF1 and VREF2 pins, allowing ground-referenced, V+-referenced, or mid-scale offset operation.
It delivers 200 kHz small-signal bandwidth, 100 dB CMRR at dc, and maintains <±10 ppm/°C gain drift over −40°C to +125°C. Input filtering capability (via external RC on +IN/−IN) and fast step recovery (<400 ns) support robust operation in noisy switching environments like H-bridge motor drives.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain | Fixed +20 V/V - enables direct scaling of shunt voltage to measurable output without external gain-setting components. |
| Common-Mode Input Range | +4.5 V to +65 V - allows direct high-side sensing across battery rails up to 60 V without level-shifting circuitry. |
| Supply Voltage | 4.5 V to 5.5 V - compatible with standard 5 V logic and microcontroller ADC reference domains. |
| Input Offset Voltage | ±200 µV max at +25°C - ensures ≤10 mV error at 500 mV full-scale shunt drop (25 A × 20 mΩ). |
| Bandwidth | 200 kHz - supports accurate current measurement in PWM-driven loads up to ~20 kHz switching frequency. |
| Operating Temperature | −40°C to +125°C - qualified for under-hood automotive and industrial motor control environments. |
| CMRR | 100 dB at dc, >70 dB at 100 kHz - rejects noise from high dv/dt power nodes during switching transitions. |
Pinout & Package
AD8210WYRZ-RL is housed in an 8-lead SOIC package (SOIC_N, JEDEC MS-012-AA), with 1.27 mm lead pitch and surface-mount footprint. Pin 4 and Pin 8 are no-connect (NC) terminals per datasheet Rev. F.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (–IN) | Inverting input | Connects to low side of shunt resistor; forms differential pair with +IN for current polarity detection. |
| 2 (GND) | Analog ground reference | Return path for internal biasing and output stage; must be tied to system analog ground, not power ground. |
| 3 (VREF2) | Reference voltage input 2 | Used with VREF1 to set output offset voltage; tied to GND or V+ for unidirectional modes, or to mid-supply for bidirectional zero-current output. |
| 4 (NC) | No connect | Internally unused; must remain floating or grounded per layout guidelines to avoid parasitic coupling. |
| 5 (OUT) | Analog output | Rail-to-rail voltage output proportional to shunt current; directly interfaces with 12-bit+ SAR ADCs or comparator inputs. |
| 6 (V+) | Positive supply | Accepts 4.5 V to 5.5 V regulated supply; decoupling capacitor (0.1 µF) required close to pin. |
| 7 (VREF1) | Reference voltage input 1 | Paired with VREF2 to configure output reference point; determines quiescent output voltage at zero differential input. |
| 8 (+IN) | Non-inverting input | Connects to high side of shunt resistor; senses voltage above common-mode range while rejecting common-mode noise. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional/unidirectional mode selection | Configurable via VREF1/VREF2 biasing - enables single device reuse across motor direction sensing and battery charge/discharge monitoring. |
| High common-mode rejection at high frequency | 70 dB CMRR maintained up to 100 kHz - preserves accuracy in presence of fast-switching gate drivers and inductive kickback. |
| Fast transient response | 400 ns rise/fall time - captures current spikes during short-circuit events or PWM edge transitions without distortion. |
| Automotive-grade qualification | AEC-Q100 Grade 1 certified - validated for operation from −40°C to +125°C ambient, supporting engine control and EPS applications. |
| Integrated ESD protection | ±2 kV HBM on all pins - eliminates need for external TVS diodes in typical 12 V/24 V automotive harness environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side current sense amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4080TASA+ | Fixed 20 V/V gain, 60 V common-mode, but only −40°C to +85°C temp range and no AEC-Q100 qualification. | Limited to commercial/industrial use; unsuitable for under-hood automotive deployment. | Select when cost sensitivity outweighs extended temperature or automotive compliance requirements. |
| INA240A1DR | 20 V/V gain, 80 V common-mode, −40°C to +125°C, AEC-Q100 Grade 1, but requires external reference for bidirectional operation. | Requires additional resistor network to set VREF, increasing design complexity and board space vs. AD8210WYRZ-RL's dual-reference-pin architecture. | Prefer when higher common-mode voltage margin (>65 V) is mandatory, such as in 72 V industrial battery systems. |
Compared with MAX4080TASA+ and INA240A1DR, AD8210WYRZ-RL uniquely combines AEC-Q100 Grade 1 qualification, integrated dual-reference configuration for seamless bidirectional operation, and optimized 65 V common-mode tolerance-making it the most compact, automotive-ready solution for 12 V/24 V EPS and BMS designs requiring minimal external components.

FAQ
What is the maximum common-mode voltage supported by the AD8210WYRZ-RL?
The AD8210WYRZ-RL supports a maximum common-mode input voltage of +65 V. This rating is specified under recommended operating conditions and allows direct connection to high-side shunts in 12 V, 24 V, and 48 V automotive and industrial systems without external level-shifting circuitry. Operation beyond +65 V risks exceeding absolute maximum ratings and may cause permanent damage to the AD8210WYRZ-RL.
Can the AD8210WYRZ-RL measure bidirectional current without external components?
Yes, the AD8210WYRZ-RL can measure bidirectional current using only its VREF1 and VREF2 pins. By applying a mid-supply voltage (e.g., 2.5 V) to both reference inputs, the output centers at half-scale (2.5 V) when shunt differential voltage is zero-enabling symmetric positive and negative current reporting. No external op-amps, resistors, or DACs are required for basic bidirectional operation of the AD8210WYRZ-RL.
What is the typical input offset voltage drift of the AD8210WYRZ-RL over temperature?
The AD8210WYRZ-RL exhibits a typical input offset voltage drift of ±10 µV/°C over the full −40°C to +125°C operating range. This value is derived from statistical distribution data in the Rev. F datasheet (Figure 34) and ensures predictable error contribution across automotive thermal profiles. The AD8210WYRZ-RL maintains this drift performance without calibration or trimming.
Does the AD8210WYRZ-RL require external filtering for PWM motor drive applications?
The AD8210WYRZ-RL supports optional external RC filtering on the +IN and −IN pins to suppress high-frequency noise from PWM switching edges. While not mandatory, a 10 Ω series resistor with 1 nF capacitor (per input) is recommended for 20 kHz motor drives to maintain >60 dB CMRR above 100 kHz. This filtering does not degrade the AD8210WYRZ-RL's 200 kHz bandwidth for fundamental current measurement.
Is the AD8210WYRZ-RL pin-compatible with other members of the AD821x family?
No, the AD8210WYRZ-RL is not pin-compatible with AD8211 or AD8212 variants. Although all share the same SOIC-8 package outline, pin functions differ significantly: AD8211 uses different reference pin assignments and lacks VREF2, while AD8212 has inverted gain polarity and distinct output stage behavior. Board-level replacement requires schematic and layout revision for each AD821x variant, including the AD8210WYRZ-RL.
