Product details
Overview
AD8210WYRZ from Analog Devices is a high-voltage, bidirectional current-sense amplifier with fixed +20 V/V gain, designed for high-side sensing 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 ±10 µV typical input offset voltage at +25°C.
For engineers reviewing the AD8210WYRZ datasheet, AD8210WYRZ pinout, AD8210WYRZ application, or AD8210WYRZ equivalent, key selection criteria include its 65 V common-mode range, unidirectional/bidirectional configuration flexibility via VREF1/VREF2, 400 ns fast response time, and AEC-Q100 Grade 1 qualification for automotive use.
Technical Context
The AD8210WYRZ integrates a precision current-sense amplifier with internal matched resistors and a proprietary high-voltage input stage enabling direct connection to shunt resistors in high-side configurations. Its differential input structure rejects common-mode transients up to 65 V while maintaining 100 dB CMRR at dc and >70 dB at 100 kHz.
Operation modes are defined by external reference voltages applied to VREF1 and VREF2: ground-referenced (output = 0 V at zero input), V+-referenced (output = V+ at zero input), or user-adjusted offset for bidirectional current measurement with programmable zero-point at mid-supply or asymmetric points.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain | +20 V/V fixed - eliminates external gain-setting components and ensures stable, temperature-invariant scaling of shunt voltage. |
| Common-Mode Input Range | +4.5 V to +65 V - enables direct high-side shunt monitoring in 12 V/24 V/48 V automotive and industrial battery systems. |
| Input Offset Voltage (typ) | ±10 µV at +25°C - supports accurate low-current sensing down to ~50 mA with 10 mΩ shunt (250 µV full-scale). |
| Response Time | 400 ns - allows real-time overcurrent detection and fast-loop protection in motor drives and DC-DC converters. |
| Supply Voltage Range | 4.5 V to 5.5 V - compatible with standard 5 V logic rails and automotive LDO outputs without level-shifting. |
| CMRR (dc) | 100 dB - rejects battery ripple and switching noise in noisy high-power environments. |
| AEC-Q100 Grade | Grade 1 (−40°C to +125°C) - qualified for under-hood automotive applications including engine control and EPS. |
Pinout & Package
AD8210WYRZ is housed in an 8-lead SOIC package (SOIC_N, JEDEC MS-012-AA), with 1.27 mm pitch, 5.00 mm × 4.00 mm body, and exposed pad not connected internally.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (–IN) | Inverting input | Connects to shunt resistor low-side terminal; forms differential pair with +IN for high-side sensing topology. |
| 2 (GND) | Analog ground reference | Return path for internal biasing and output stage; must be tied to system power ground with low-impedance connection. |
| 3 (VREF2) | Reference input 2 | Used with VREF1 to set output offset voltage; floating or tied to GND/V+ defines unidirectional mode polarity. |
| 4 (NC) | No connect | Internally unused; must remain unconnected per datasheet to avoid parasitic coupling or latch-up risk. |
| 5 (OUT) | Analog output | Rail-to-rail voltage output proportional to shunt current; directly interfaces with ADC inputs or comparator thresholds. |
| 6 (V+) | Positive supply | 5 V nominal supply input; powers internal amplifier and reference circuitry; bypass capacitor required at pin. |
| 7 (VREF1) | Reference input 1 | Primary offset control pin; combined with VREF2 determines zero-current output voltage (e.g., 0 V, 5 V, or 2.5 V). |
| 8 (+IN) | Non-inverting input | Connects to shunt resistor high-side terminal; senses voltage above common-mode rail up to +65 V. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional current sensing | Configurable zero-point via dual reference pins enables symmetric ±125 mV input range or asymmetric ranges for motor phase current profiling. |
| High common-mode rejection | 100 dB CMRR at dc and ≥70 dB at 100 kHz ensures accurate current measurement despite battery ripple or PWM noise. |
| Fast transient response | 400 ns propagation delay supports cycle-by-cycle overcurrent protection in synchronous buck converters and H-bridge drivers. |
| Automotive-grade reliability | AEC-Q100 Grade 1 qualification and −40°C to +125°C operating range meet requirements for engine control units and battery management. |
| Fixed-gain architecture | +20 V/V gain eliminates external resistor matching errors and drift, improving long-term accuracy in harsh thermal 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+ | +20 V/V gain, 76 V common-mode range, but only unidirectional output swing (0.05 V to 4.9 V); no VREF2 pin for bidirectional offset tuning. | Limited to unidirectional current monitoring; unsuitable for regenerative braking or H-bridge bidirectional control. | Select when only forward current sensing is needed and higher common-mode tolerance (>65 V) is critical. |
| INA240A1D | −4 V/V gain (inverting), 80 V common-mode, integrated EMI filter, but requires external gain inversion and lacks VREF-configurable offset. | Requires signal inversion stage and additional passive components; not drop-in for AD8210WYRZ's non-inverting +20× architecture. | Choose for ultra-low offset drift (±0.2 µV/°C) and enhanced EMI immunity in noisy industrial inverters. |
Compared with MAX4080TASA+ and INA240A1D, the AD8210WYRZ uniquely combines bidirectional configurability, fixed non-inverting gain, and AEC-Q100 Grade 1 qualification-making it optimal for automotive EPS and bidirectional 48 V BMS where offset programmability and functional safety alignment are essential.

FAQ
What is the maximum common-mode voltage the AD8210WYRZ can handle?
The AD8210WYRZ supports a common-mode input voltage range from +4.5 V to +65 V. This allows direct connection to shunt resistors on high-side power rails in 12 V, 24 V, and 48 V automotive and industrial systems. Operation beyond +65 V risks exceeding absolute maximum ratings and is not supported.
Can the AD8210WYRZ measure bidirectional current without external components?
Yes-the AD8210WYRZ supports true bidirectional current sensing using only external reference voltages applied to VREF1 and VREF2. By setting both pins to mid-supply (e.g., 2.5 V), the output centers at 2.5 V for zero current, enabling ±125 mV input range detection without op-amps or level shifters.
Is the AD8210WYRZ pin-compatible with other members of the AD8210 family?
Yes-AD8210WYRZ shares identical pinout, package (8-lead SOIC), and electrical interface with AD8210YRZ and AD8210BRZ. All variants use the same VREF1/VREF2 configuration scheme and gain architecture, enabling direct substitution where grade-level requirements align.
What is the typical input offset voltage drift over temperature for the AD8210WYRZ?
The AD8210WYRZ exhibits ±0.1 µV/°C typical input offset voltage drift over −40°C to +125°C. This low drift-combined with ±10 µV initial offset-ensures stable current measurement accuracy across automotive under-hood thermal cycles without recalibration.
Does the AD8210WYRZ require external gain-setting resistors?
No-the AD8210WYRZ features a factory-trimmed, fixed +20 V/V gain implemented with laser-trimmed internal thin-film resistors. This eliminates external gain components, reduces layout sensitivity, and maintains ±0.3% gain error over temperature-critical for production consistency.
