Product details
Overview
AD8417WBRMZ-RL from Analog Devices is a bidirectional, zero-drift current sense amplifier optimized for high-side and low-side shunt-based current measurement in automotive motor and solenoid control. It delivers 60 V/V fixed gain, ±400 µV max input offset over −40°C to +125°C, 250 kHz bandwidth, and operates from 2.7 V to 5.5 V supply with −2 V to +70 V continuous common-mode input range.
For engineers reviewing the AD8417WBRMZ-RL datasheet, AD8417WBRMZ-RL pinout, AD8417WBRMZ-RL application, or AD8417WBRMZ-RL equivalent, this page provides verified specifications, FMEA-tolerant 10-lead MSOP package details, AEC-Q100 qualification status, EMI-filtered PWM-compatible operation, and real-world motor/solenoid diagnostic use cases.
Technical Context
The AD8417WBRMZ-RL implements a patented zero-drift difference amplifier architecture (U.S. Patent 8,624,668 B2) that maintains 250 kHz bandwidth while achieving 0.1 µV/°C typical offset drift and 86 dB CMRR from dc to 10 kHz. Its input stage rejects fast PWM common-mode transients up to 1 V/ns without degradation.
It supports unidirectional and bidirectional configurations via dual reference inputs (VREF1/VREF2), enabling ground-referenced, supply-referenced, or externally referenced output offsets - all ratiometric to VS when used as a voltage divider. The device is internally compensated and requires no external components for stable operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain | 60 V/V fixed - enables direct interface to 12-bit+ ADCs with 50 mΩ shunt at ±50 A full-scale. |
| Input Offset Voltage (max) | ±400 µV over −40°C to +125°C - ensures ≤±6.7 mV output error at full gain, critical for precision torque control. |
| Common-Mode Range | −2 V to +70 V continuous - supports high-side sensing in 12 V/24 V automotive systems with battery transients. |
| Bandwidth | 250 kHz - captures fast current transients in H-bridge commutation and PWM-driven solenoids. |
| Supply Voltage | 2.7 V to 5.5 V - compatible with standard 3.3 V and 5 V microcontroller domains without level-shifting. |
| CMRR | 86 dB (dc to 10 kHz) - suppresses noise coupling from adjacent power switches in dense motor drive PCB layouts. |
| Quiescent Current | 4.1 mA at −40°C to +125°C - enables always-on diagnostics in safety-critical automotive modules. |
Pinout & Package
AD8417WBRMZ-RL is housed in a RoHS-compliant, lead-free 10-lead MSOP package (RM-10), designed for failure mode and effects analysis (FMEA) compliance per automotive functional safety requirements. The package features NC pins inserted between critical nodes (−IN/GND and +IN/VREF1) to prevent short-induced latch-up or rail-to-rail fault propagation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (−IN) | Negative Input | Connects to shunt resistor low-side; accepts −2 V to +70 V common-mode voltage. |
| 2 (NC) | No Connect | FMEA guard pin - electrically isolated to prevent shorts between −IN and GND. |
| 3 (GND) | Ground Reference | System ground return; internal EMI filter ties to this node for noise suppression. |
| 4 (VREF2) | Reference Input 2 | Adjusts output offset; tied with VREF1 to set bidirectional zero point (e.g., VS/2). |
| 5 (NC) | No Connect | FMEA guard pin - isolates VREF2 from adjacent +IN to avoid reference corruption. |
| 6 (OUT) | Analog Output | Buffered 60× amplified shunt voltage; drives 25 kΩ load down to 45 mV above GND. |
| 7 (VS) | Positive Supply | 2.7 V–5.5 V single supply; powers internal amplifiers and EMI filters. |
| 8 (VREF1) | Reference Input 1 | Dual with VREF2; forms ratiometric divider for supply-referenced offset calibration. |
| 9 (NC) | No Connect | FMEA guard pin - isolates VREF1 from +IN to maintain reference integrity under fault. |
| 10 (+IN) | Positive Input | Connects to shunt resistor high-side; completes differential measurement path. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for −40°C to +125°C operation in automotive ECUs, meeting ISO 26262 ASIL-B readiness requirements. |
| EMI-filtered inputs | Integrated RC filtering on both inputs suppresses >100 MHz RF interference from nearby inverters or ignition systems. |
| PWM common-mode rejection | Patented architecture rejects fast dV/dt transients (up to 1 V/ns) without output ringing or settling delay. |
| Bidirectional current sensing | VREF1/VREF2 configuration enables true bipolar output (e.g., 0.5 V to 4.5 V for ±50 A), eliminating need for external op-amps. |
| FMEA-tolerant 10-lead MSOP | Strategic NC pins prevent catastrophic failure modes from solder bridging or trace shorts in high-reliability production. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar current sense amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD8418ARZ-R7 | 20 V/V gain, ±150 µV max offset, SOIC-8 package, same AEC-Q100 Grade 1 rating. | Lower gain requires larger shunt or post-amplification; lacks FMEA-optimized pinout. | Select when lower gain suffices and cost-sensitive SOIC-8 layout is preferred over FMEA robustness. |
| INA240A1QPWRQ1 | 20 V/V gain, −5 V to +85 V common-mode, 4 V/V to 500 V/V selectable gain via external resistors. | Requires external gain-setting resistors and compensation; wider common-mode but higher quiescent current (2.4 mA vs. 4.1 mA). | Choose for ultra-high common-mode (>70 V) or programmable gain needs, accepting added BOM count and layout complexity. |
Compared with AD8417WBRMZ-RL, AD8418ARZ-R7 offers tighter offset but sacrifices gain and FMEA resilience, while INA240A1QPWRQ1 extends voltage range at the cost of design simplicity and power efficiency - making AD8417WBRMZ-RL optimal for AEC-Q100-compliant, high-accuracy, high-reliability motor/solenoid sensing where fixed 60× gain and integrated fault tolerance are essential.

FAQ
What is the operating temperature range for AD8417WBRMZ-RL?
The AD8417WBRMZ-RL is rated for −40°C to +125°C operation, meeting AEC-Q100 Grade 1 requirements. This range is validated across all electrical parameters including gain error (±0.3%), offset drift (≤0.4 µV/°C), and CMRR (≥86 dB), ensuring reliable performance in under-hood automotive environments and industrial motor drives.
Does AD8417WBRMZ-RL support bidirectional current sensing out of the box?
Yes, AD8417WBRMZ-RL natively supports bidirectional current sensing via its dual reference inputs (VREF1 and VREF2). When configured with one pin tied to VS and the other to GND, it produces a ratiometric mid-supply output (e.g., 2.5 V at 5 V supply) for symmetric ±50 A measurement - no external components or calibration required.
What makes the 10-lead MSOP package of AD8417WBRMZ-RL FMEA-tolerant?
The AD8417WBRMZ-RL's 10-lead MSOP inserts NC pins between −IN/GND and +IN/VREF1 to physically isolate high-voltage input nodes from ground and reference paths. Per Table 6 in the datasheet, this layout ensures the device remains functional even if adjacent pins short on PCB - a key requirement for ISO 26262-compliant automotive designs.
Can AD8417WBRMZ-RL reject fast PWM common-mode transients?
Yes, AD8417WBRMZ-RL incorporates patented circuitry (U.S. Patent 8,624,668 B2) that actively cancels fast dV/dt common-mode transients up to 1 V/ns. This enables accurate current measurement in H-bridge motor drivers and solenoid controllers where input common-mode voltage swings rapidly between −2 V and +70 V.
Is AD8417WBRMZ-RL pin-compatible with other AD8417 variants?
No - AD8417WBRMZ-RL uses the 10-lead MSOP FMEA-optimized pinout, which differs electrically and mechanically from the 8-lead MSOP (AD8417WB) and SOIC_N (AD8417B) variants. Pin 1 (−IN) and pin 10 (+IN) retain identical function, but the inserted NC pins (2, 5, 9) and relocated VREF/GND/VS positions require dedicated PCB layout.
