Product details
Overview
AD8215WYRZ-RL from Analog Devices is an automotive-qualified, high-voltage current shunt monitor with fixed 20 V/V gain, ±0.3% max gain error over −40°C to +125°C, −2 V to +65 V common-mode input range, and buffered output for direct ADC interfacing in high-side motor control sensing.
For engineers reviewing the AD8215WYRZ-RL datasheet, AD8215WYRZ-RL pinout, AD8215WYRZ-RL application, or AD8215WYRZ-RL equivalent, this page delivers verified specifications, functional context, real-world use cases, and validated alternatives for automotive and industrial current monitoring designs.
Technical Context
The AD8215WYRZ-RL employs a proprietary high-common-mode-input amplifier architecture with precision-trimmed internal resistors (0.01% matching) to deliver stable 20 V/V gain across −2 V to +65 V common-mode voltage. Its input stage maintains linearity down to 2 mV differential input regardless of common-mode level.
It features dedicated offset circuitry enabling ±2.5 mV RTI offset over temperature, 120 dB dc CMRR, and 450 kHz small-signal bandwidth-optimized for unidirectional current measurement in PWM-driven inductive loads with recirculation current capture.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain | 20 V/V, ±0.3% max error over −40°C to +125°C - enables accurate current-to-voltage conversion without external gain calibration. |
| Common-Mode Input Range | −2 V to +65 V continuous - supports high-side sensing in 12 V/24 V/48 V automotive and industrial power rails. |
| Input Offset Voltage (RTI) | ±2.5 mV over temperature - ensures ≤125 µA error at 50 mΩ shunt, critical for low-current fault detection. |
| CMRR | 120 dB typical at dc - rejects battery ripple and switching noise in engine management and transmission controls. |
| Small-Signal Bandwidth | 450 kHz - captures fast current transients in motor phase current feedback loops. |
| Supply Voltage | 4.5 V to 5.5 V - compatible with standard 5 V automotive microcontroller domains. |
| ESD Rating | ±4000 V HBM - meets automotive robustness requirements for under-hood environments. |
Pinout & Package
AD8215WYRZ-RL is housed in an 8-lead SOIC_N (JEDEC MS-012-AA, R-8) package, 5.00 mm × 4.00 mm × 1.75 mm, RoHS-compliant, rated for −40°C to +125°C ambient operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (−IN) | Inverting Input | High-impedance node referenced to common-mode voltage; connects to shunt low-side in high-side sensing configurations. |
| 2 (GND) | Analog Ground | Reference for output buffer and internal circuitry; must be tied to system analog ground with low-impedance path. |
| 3, 4, 7 (NC) | No Connect | Internally unconnected; must remain floating - no PCB trace or soldering allowed. |
| 5 (OUT) | Buffered Output | Low-impedance (2 Ω), rail-to-rail capable (0.1 V to 4.9 V) voltage output directly drives 12-bit+ SAR ADCs. |
| 6 (V+) | Positive Supply | 5 V ±5% supply input; powers all internal stages and output buffer; bypass capacitor required at pin. |
| 8 (+IN) | Noninverting Input | High-impedance node; connects to shunt high-side - senses current direction and magnitude in unidirectional applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage current shunt monitor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4080TASA+ | Fixed 20 V/V gain, but only −0.1 V to +65 V common-mode range; no automotive qualification; 8-lead SOIC package. | Limited to non-automotive industrial DC-DC or motor drives where −2 V startup margin is not required. | Select when cost sensitivity outweighs automotive compliance and sub-zero common-mode capability. |
| TSC2101IDR | 20 V/V gain, −5 V to +65 V common-mode, but ±1.5% gain error over temperature and no AEC-Q100 rating. | Suitable for commercial-grade battery management or HVAC blower control, not safety-critical ECU functions. | Choose only for non-automotive applications requiring extended negative common-mode headroom beyond −2 V. |
Compared with MAX4080TASA+ and TSC2101IDR, AD8215WYRZ-RL uniquely combines AEC-Q100 qualification, −2 V to +65 V guaranteed common-mode operation, and ±0.3% gain error - making it the only option qualified for engine management and transmission control systems requiring ISO 26262-aligned current sensing.

FAQ
What is the guaranteed common-mode input voltage range for AD8215WYRZ-RL?
The AD8215WYRZ-RL guarantees continuous operation from −2 V to +65 V common-mode input voltage, with survival rating up to −3 V to +68 V. This range is validated per datasheet Table 1 and Absolute Maximum Ratings, enabling reliable high-side sensing in 12 V automotive systems during load dump and cold-crank conditions where rail voltage dips below ground.
Does AD8215WYRZ-RL support bidirectional current measurement?
No, AD8215WYRZ-RL is designed exclusively for unidirectional current measurement. Its internal architecture and output swing (0.1 V to 4.9 V) do not support negative differential inputs or bipolar output scaling. For bidirectional sensing, Analog Devices recommends the AD8210 or AD8217, which provide symmetric output ranges around mid-supply.
What is the maximum differential input voltage the AD8215WYRZ-RL can handle without saturation?
The AD8215WYRZ-RL maintains linearity up to 250 mV differential input voltage, as specified in the "Differential Input Voltage Range" parameter in Table 1. Exceeding this value causes output clipping; for example, with a 50 mΩ shunt, 250 mV corresponds to 5 A full-scale current, defining the upper limit for accurate measurement.
Is AD8215WYRZ-RL pin-compatible with other members of the AD8215 family?
Yes, AD8215WYRZ-RL shares identical 8-lead SOIC_N (R-8) pinout and electrical behavior with AD8215YRZ-RL and AD8215WYRZ. The "W" suffix denotes automotive qualification, but mechanical layout, thermal characteristics, and pin functions are fully interchangeable - allowing drop-in replacement in existing designs meeting AEC-Q100 requirements.
How does the AD8215WYRZ-RL handle input bias current variation with common-mode voltage?
AD8215WYRZ-RL exhibits input bias current that varies with common-mode voltage: Figure 11 shows ~−0.5 mA at VCM = 0 V, rising to ~+1.2 mA at VCM = 65 V. This behavior is inherent to its high-voltage input stage and must be accounted for in shunt resistor selection to avoid gain error - typically mitigated using ≥5 kΩ differential input impedance per datasheet Table 1.
