Product details
Overview
AD8210YRZ-REEL 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 achieves ±0.5 mV input offset voltage at +25°C. It is used in H-bridge motor control and high-side current sensing with low-side switches.
For engineers reviewing the AD8210YRZ-REEL datasheet, AD8210YRZ-REEL pinout, AD8210YRZ-REEL application, or AD8210YRZ-REEL equivalent, key selection criteria include its 65 V common-mode range, 200 kHz bandwidth, 70 dB CMRR at DC, −40°C to +125°C operating temperature, and SOIC-8 package compatibility with automotive-grade reliability requirements.
Technical Context
The AD8210YRZ-REEL integrates a precision current-sense amplifier with internal matched resistors and a differential input stage optimized for high common-mode rejection. Its architecture enables accurate amplification of small shunt voltage drops while rejecting large common-mode transients typical in battery-fed systems.
It supports three operational modes-ground-referenced output, V+-referenced output, and bidirectional output-via configurable VREF1 and VREF2 pins. Output offset is programmable from 0 V to VS, enabling flexible full-scale current mapping without external op-amps or level-shifting circuitry.

Pinout & Package
AD8210YRZ-REEL is housed in an 8-lead SOIC package (JEDEC MS-012-AA), with gull-wing leads, 1.27 mm pitch, and exposed pad not connected internally. 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 shunt resistor low side; referenced to common-mode voltage |
| 2 (GND) | Analog ground | Return path for internal biasing; must be tied to system ground near shunt |
| 3 (VREF2) | Reference input 2 | Configures output offset; tied to GND or V+ for unidirectional modes |
| 4 (NC) | No connect | Not bonded; must remain floating or grounded per layout guidelines |
| 5 (OUT) | Amplified output | Rail-to-rail voltage output proportional to shunt voltage × 20 |
| 6 (V+) | Positive supply | 4.5 V to 5.5 V analog supply; decoupling capacitor required |
| 7 (VREF1) | Reference input 1 | Paired with VREF2 to set output quiescent voltage (e.g., 0 V or 2.5 V) |
| 8 (+IN) | Non-inverting input | Connects to shunt resistor high side; senses current direction and magnitude |
Key Features
| Feature | Design Value |

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 100 kHz bandwidth and no VREF configuration for bidirectional mode | Limited to unidirectional sensing; lacks programmable offset for center-zero applications | Choose when higher common-mode voltage (76 V) is critical and bidirectional operation is unnecessary |
| INA240A1DR | 20 V/V gain, 80 V common-mode, 400 kHz bandwidth, but requires external reference for offset setting and has higher offset drift (±0.5 µV/°C) | Supports wider bandwidth and higher common-mode, but adds design complexity with external VREF network | Prefer when faster response is needed and board space allows for reference divider and filtering |
Compared with MAX4080TASA+ and INA240A1DR, the AD8210YRZ-REEL uniquely combines programmable bidirectional offset, automotive qualification, and integrated gain resistors in SOIC-8-reducing BOM count and layout sensitivity while maintaining 200 kHz bandwidth and 65 V common-mode capability.

FAQ
What is the maximum common-mode voltage supported by the AD8210YRZ-REEL?
The AD8210YRZ-REEL supports a maximum common-mode input voltage of +65 V, as specified in the Absolute Maximum Ratings table of Rev. F datasheet. This rating applies across the full operating temperature range (−40°C to +125°C) and enables direct interface with 48 V automotive buses and industrial 60 V systems without external attenuation or level shifting. The device maintains functional performance up to this limit, not just survival.
Can the AD8210YRZ-REEL measure bidirectional current, and how is it configured?
Yes, the AD8210YRZ-REEL supports bidirectional current measurement by applying appropriate voltages to VREF1 and VREF2 pins to set the output quiescent level-for example, 2.5 V at V+ = 5 V. When VIN (across +IN/–IN) is zero, output sits at mid-supply; positive inputs raise output, negative inputs lower it. Table 6 in the Rev. F datasheet confirms ±125 mV input maps to 0.05 V and 4.9 V output respectively, enabling true bipolar sensing.
What is the gain accuracy and drift specification for the AD8210YRZ-REEL?
The AD8210YRZ-REEL features a fixed +20 V/V gain with ±0.3% gain error at +25°C and ±50 ppm/°C gain drift over temperature, as verified in Figure 33 and Table 3 of Rev. F. These values ensure predictable scaling from shunt voltage to output-e.g., 100 mV across RSHUNT yields 2.00 V ±6 mV output-without requiring factory calibration or trimming resistors.
Is the AD8210YRZ-REEL AEC-Q100 qualified, and which grade does it meet?
Yes, the AD8210YRZ-REEL is AEC-Q100 qualified per Rev. F datasheet Section "Automotive Products" and meets Grade 1 requirements (−40°C to +125°C ambient operating temperature). It undergoes stress testing including HTOL, TC, UHAST, and ESD (±2 kV HBM), and is manufactured in certified automotive production lines with PPAP documentation available upon request.
Does the AD8210YRZ-REEL require external components for basic operation?
The AD8210YRZ-REEL requires only two external 0.1 µF ceramic decoupling capacitors-one on V+ and one on OUT-as shown in Figures 28–29 of Rev. F. No external gain-setting resistors, level shifters, or compensation networks are needed due to its fully integrated architecture. VREF1/VREF2 may be tied directly to GND or V+ for unidirectional modes, or driven externally for custom offset.
