Product details
Overview
AD8210YRZ 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 ±250 mV differential input range for shunt-based current monitoring in motor control and battery management.
For engineers reviewing the AD8210YRZ datasheet, AD8210YRZ pinout, AD8210YRZ application, or AD8210YRZ equivalent, key selection criteria include its 65 V common-mode voltage capability, unidirectional/bidirectional configuration flexibility via VREF1/VREF2, <1 µs response time, and AEC-Q100 Grade 1 qualification for automotive use.
Technical Context
The AD8210YRZ integrates a precision current-sense amplifier with internal matched resistors and a proprietary high-voltage input stage enabling direct connection to high-side shunts. Its architecture supports three operational modes-ground-referenced, V+-referenced, and bidirectional-configured by external reference voltages applied to VREF1 and VREF2 pins.
It achieves 100 dB CMRR at dc and >70 dB up to 100 kHz, maintains ±0.5% gain error over temperature (−40°C to +125°C), and provides 120 µV max input offset voltage at +25°C. Output drives loads down to 10 kΩ while sourcing/sinking ≥1 mA across full temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain | +20 V/V fixed, enables direct scaling of 25 mV shunt drop to 500 mV output for ADC interfacing. |
| Common-Mode Input Range | +65 V max, allows direct high-side sensing in 12 V/24 V/48 V automotive and industrial bus systems. |
| Supply Voltage | 4.5 V to 5.5 V, compatible with standard 5 V logic rails and automotive LDO outputs. |
| Input Offset Voltage | ±120 µV max at +25°C, ensures ≤6 µV error contribution from sense resistor voltage drop. |
| Response Time | ≤1 µs (10%–90%), supports fast overcurrent detection in motor drive and protection circuits. |
| Operating Temperature | −40°C to +125°C, qualified per AEC-Q100 Grade 1 for under-hood automotive applications. |
| CMRR | 100 dB at dc, >70 dB at 100 kHz, rejects noise from switching power stages and battery transients. |
Pinout & Package
AD8210YRZ is housed in an 8-lead SOIC package (JEDEC MS-012-AA), 4.9 mm × 3.9 mm footprint, 1.27 mm pitch, with exposed pad for thermal enhancement (not electrically connected).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (−IN) | Inverting input | Connects to low side of shunt; referenced to common-mode voltage up to +65 V. |
| 2 (GND) | Analog ground | Reference node for internal circuitry and output swing; must be tied to system ground. |
| 3 (VREF2) | Reference input 2 | Configures output offset: tied to GND for ground-referenced mode, to V+ for V+-referenced mode. |
| 4 (NC) | No connect | Internally unused; must remain floating or grounded per layout guidelines. |
| 5 (OUT) | Analog output | Rail-to-rail voltage output proportional to shunt current; drives ADC inputs directly. |
| 6 (V+) | Positive supply | 4.5 V–5.5 V analog supply; bypass with 0.1 µF ceramic capacitor near pin. |
| 7 (VREF1) | Reference input 1 | Paired with VREF2 to set bidirectional zero-current output voltage (e.g., 2.5 V for ±125 mV range). |
| 8 (+IN) | Non-inverting input | Connects to high side of shunt; withstands +65 V common-mode voltage relative to GND. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional current sensing | Output offset programmable via VREF1/VREF2 to support symmetric (±125 mV) or asymmetric current ranges. |

| Fast transient response | 1 µs rise/fall time enables real-time overcurrent detection in H-bridge and PWM motor drivers. |
| AEC-Q100 Grade 1 qualification | Validated for −40°C to +125°C operation with lifetime reliability testing for automotive powertrain modules. |
| Integrated precision gain | +20 V/V fixed gain eliminates external resistor matching errors and reduces BOM count in production designs. |

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, 76 V common-mode, but only unidirectional output; no VREF1/VREF2 for bidirectional offset tuning. | Suitable for single-direction battery charging or supply monitoring; not usable in H-bridge or regenerative braking. | Select when bidirectional sensing is unnecessary and higher common-mode voltage (>65 V) is required. |
| INA240A1DR | Adjustable gain (20–500 V/V), 80 V common-mode, integrated EMI filtering, but requires external gain-setting resistor. | Offers wider dynamic range and better noise immunity; lacks factory-trimmed gain accuracy of AD8210YRZ. | Prefer when system-level gain calibration is acceptable and enhanced EMC robustness is prioritized. |

FAQ
What is the maximum common-mode voltage supported by the AD8210YRZ?
The AD8210YRZ supports a maximum common-mode input voltage of +65 V, enabling direct high-side shunt sensing in 12 V, 24 V, and 48 V automotive and industrial power systems without level-shifting circuitry. This rating is specified across the full operating temperature range (−40°C to +125°C) and is validated per AEC-Q100 stress tests.
Can the AD8210YRZ measure bidirectional current, and how is it configured?
Yes, the AD8210YRZ supports bidirectional current measurement by applying a mid-supply voltage (e.g., 2.5 V) to both VREF1 and VREF2 pins, setting the zero-current output to half-scale. This enables ±125 mV differential input range mapping to 0.05 V–4.9 V output, allowing forward/reverse current detection in H-bridge motor control without external op-amps or level shifters.
Does the AD8210YRZ require external gain-setting components?
No, the AD8210YRZ features a factory-trimmed fixed gain of +20 V/V, eliminating the need for external resistors or calibration. This ensures consistent gain accuracy (±0.5% max over temperature) and simplifies PCB layout, reducing BOM cost and improving production yield compared to adjustable-gain alternatives like the INA240 series.
What is the typical response time of the AD8210YRZ, and how does it impact overcurrent protection?
The AD8210YRZ has a typical rise/fall time of ≤1 µs, enabling detection of fast current transients such as short-circuits or motor stalls. This sub-microsecond response allows integration into real-time protection loops that meet ISO 26262 ASIL-B timing constraints, ensuring safe shutdown before MOSFET destruction in motor driver applications.
Is the AD8210YRZ qualified for automotive applications, and what grade does it meet?
Yes, the AD8210YRZ is AEC-Q100 qualified to Grade 1 (−40°C to +125°C ambient), with full reliability testing including HTOL, TC, UHAST, and ESD. It is widely deployed in automotive battery management systems, electric power steering, and body control modules where long-term stability and failure-rate predictability are mandatory.
