Product details
Overview
AD8210YRZ-REEL7 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 max input offset voltage at +25°C. It is used in H-bridge motor control and battery protection circuits where accurate shunt-based current monitoring is required.
For engineers reviewing the AD8210YRZ-REEL7 datasheet, AD8210YRZ-REEL7 pinout, AD8210YRZ-REEL7 application, or AD8210YRZ-REEL7 equivalent, key selection criteria include common-mode rejection at 100 kHz (≥80 dB), unidirectional/bidirectional mode configurability via VREF pins, temperature-stable gain error (±50 ppm/°C max), and AEC-Q100 Grade 1 qualification for automotive use.
Technical Context
The AD8210YRZ-REEL7 integrates a precision current-sense amplifier with internal matched resistors and a proprietary high-voltage input stage enabling direct connection to shunts in high-side configurations. Its differential input accepts signals referenced to up to +65 V common-mode voltage while rejecting noise via >100 dB CMRR at dc and >80 dB at 100 kHz.
Operation supports three modes-ground-referenced output, V+-referenced output, and bidirectional output-configured by tying VREF1 and VREF2 to GND, VS, or external bias. Output swings rail-to-rail (0.05 V to 4.9 V at VS = 5 V), with 400 ns typical response time and <0.1% gain nonlinearity over full-scale range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain | Fixed +20 V/V - enables direct scaling of shunt voltage to 20× for improved ADC resolution without external gain stages. |
| Common-Mode Input Range | +65 V max - allows direct high-side sensing across battery rails in 12 V/24 V automotive systems without level-shifting circuitry. |
| Input Offset Voltage | ±10 µV max at +25°C - ensures sub-mA error in 1 mΩ shunt applications (e.g., 500 A full scale). |
| CMRR | 100 dB @ dc, ≥80 dB @ 100 kHz - maintains accuracy during PWM switching transients in motor drives and DC-DC converters. |
| Supply Voltage | 4.5 V to 5.5 V - compatible with standard 5 V logic and microcontroller I/O domains, eliminating need for LDO regulation. |
| Output Swing | 0.05 V to 4.9 V @ VS = 5 V - delivers full dynamic range to 12-bit+ SAR ADCs without clamping or signal loss. |
| Bandwidth | 1 MHz - supports fast transient detection in overcurrent protection schemes with ≤1 µs response latency. |
Pinout & Package
AD8210YRZ-REEL7 is housed in an 8-lead SOIC package (SOIC_N) compliant with JEDEC MS-012-AA, with 1.27 mm lead pitch and gull-wing leads. The package is RoHS-compliant and rated for operation from −40°C to +125°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (–IN) | Inverting input | Connects to low side of shunt resistor; forms differential pair with +IN to reject common-mode voltage. |
| 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 input 2 | Configures output offset: grounded for ground-referenced mode, tied to VS for V+-referenced mode, or biased externally for bidirectional operation. |
| 4 (NC) | No connect | Internally unused; must remain floating-no PCB trace or solder connection permitted. |
| 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; decoupling capacitor (0.1 µF) required between V+ and GND near the pin. |
| 7 (VREF1) | Reference input 1 | Paired with VREF2 to set output quiescent voltage; both pins define offset point for bidirectional measurement range. |
| 8 (+IN) | Non-inverting input | Connects to high side of shunt resistor; senses current direction and magnitude relative to –IN. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualified | Rated for −40°C to +125°C ambient operation with full parametric performance-enables use in engine control, transmission, and battery management modules. |
| Bidirectional current sensing | VREF1/VREF2 pins allow precise output offset adjustment (e.g., 2.5 V at zero current), enabling symmetric ±125 mV input range for reversible motor or regenerative braking current measurement. |
| High-speed transient response | 400 ns rise/fall time with <1% overshoot-supports real-time overcurrent shutdown in IGBT/MOSFET gate drivers without added delay. |
| Integrated EMI filtering | Internal RF filter design suppresses >100 MHz noise from switching nodes, reducing need for external RC filters in noisy 48 V automotive subsystems. |
| Low quiescent current | 5.5 mA max at +25°C-minimizes self-heating in always-on battery monitoring circuits and extends standby runtime in telematics units. |

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, but only supports +76 V max common-mode; no AEC-Q100 qualification; higher input offset (±200 µV). | Suitable for industrial 48 V systems but not automotive under-hood environments requiring Grade 1 reliability. | Select when cost sensitivity outweighs automotive qualification needs and common-mode voltage stays below +76 V. |
| INA240A1QDRQ1 | Adjustable gain (20×/50×/100×); AEC-Q100 Grade 1; lower offset (±5 µV); wider supply (2.7–5.5 V); slower bandwidth (400 kHz). | Better suited for ultra-precision battery monitoring where gain flexibility and lower offset dominate over speed. | Prefer when multi-range sensing or tighter offset spec is critical, and 400 ns response is not required. |
Compared with MAX4080TASA+ and INA240A1QDRQ1, the AD8210YRZ-REEL7 offers optimal balance of speed (1 MHz BW), automotive qualification, and fixed-gain simplicity-making it ideal for cost-constrained, high-reliability motor control and battery protection where 400 ns response and +65 V CM capability are mandatory.

FAQ
What is the maximum common-mode voltage supported by the AD8210YRZ-REEL7?
The AD8210YRZ-REEL7 supports a maximum common-mode input voltage of +65 V. This rating is specified under normal operating conditions with VS = 5 V and applies to both +IN and –IN pins referenced to GND. Operation beyond this voltage risks permanent damage and is not guaranteed by the datasheet. The device achieves this using a proprietary high-voltage input cell that isolates the core amplifier from rail stress.
Can the AD8210YRZ-REEL7 measure bidirectional current, and how is it configured?
Yes, the AD8210YRZ-REEL7 supports bidirectional current measurement by applying a bias voltage to VREF1 and VREF2 pins. When both pins are set to 2.5 V (e.g., via resistor divider from VS), the output rests at 2.5 V at zero differential input, enabling ±125 mV input range for symmetric positive/negative current flow. Configuration requires no external op amps or additional passive components-only proper reference voltage sourcing.
Is the AD8210YRZ-REEL7 qualified for automotive applications?
Yes, the AD8210YRZ-REEL7 is AEC-Q100 Grade 1 qualified (−40°C to +125°C ambient), with full electrical specifications guaranteed across that range. It includes enhanced electrostatic discharge (ESD) protection, robust latch-up immunity, and validated reliability testing per automotive standards-making it suitable for engine control units, battery disconnect units, and ADAS power domains.
What is the typical response time of the AD8210YRZ-REEL7 to current transients?
The AD8210YRZ-REEL7 exhibits a typical rise and fall time of 400 ns with minimal overshoot (<1%), measured under standard test conditions (VS = 5 V, RL = 10 kΩ, CL = 100 pF). This response enables reliable detection of fast overcurrent events in motor drives and switch-mode power supplies, supporting cycle-by-cycle protection schemes without introducing significant propagation delay.
Does the AD8210YRZ-REEL7 require external gain-setting resistors?
No, the AD8210YRZ-REEL7 features a factory-trimmed, fixed gain of +20 V/V. Internal laser-trimmed thin-film resistors eliminate external gain components, reduce board space, and avoid resistor tolerance-induced errors. Gain accuracy is ±0.5% over temperature, and no external configuration is needed to achieve nominal 20× scaling of shunt voltage to output voltage.
