Product details
Overview
AD8417WBRMZ-10RL from Analog Devices is a bidirectional, zero-drift current sense amplifier with 60 V/V fixed gain, ±400 µV max input offset over −40°C to +150°C, and −2 V to +70 V continuous common-mode input range. It delivers high-accuracy shunt-based current measurement in automotive motor control and solenoid driver circuits where PWM rejection and thermal stability are critical.
For engineers reviewing the AD8417WBRMZ-10RL datasheet, AD8417WBRMZ-10RL pinout, AD8417WBRMZ-10RL application, or AD8417WBRMZ-10RL equivalent, this page provides verified specifications, FMEA-tolerant 10-lead MSOP package details, bidirectional output configuration guidance, and automotive-grade AEC-Q100 qualification context - all grounded in Rev. E datasheet parameters.
Technical Context
The AD8417WBRMZ-10RL implements a patented zero-drift architecture (U.S. Patent 8,624,668 B2) enabling 0.1 µV/°C typical offset drift while maintaining 250 kHz bandwidth 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 flexible output offset adjustment via dual reference pins (VREF1/VREF2), allowing ground-referenced, supply-referenced, external-referenced, or ratiometric mid-scale (VS/2) operation - essential for bidirectional current sensing in H-bridge and 3-phase motor drives.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain | 60 V/V fixed - enables direct scaling of 50 mV shunt voltage to 3 V full-scale output for 12-bit ADC interfacing. |
| Input Offset Voltage (max) | ±400 µV over −40°C to +150°C - ensures ≤6.7 mV total error at 60× gain across full automotive temperature range. |
| Common-Mode Range | −2 V to +70 V continuous - supports high-side sensing in 12 V/24 V/48 V battery systems with load-dump and cold-crank margins. |
| CMRR | 86 dB (dc to 10 kHz) - maintains accuracy during PWM switching with <0.5% gain error at 10 kHz common-mode ripple. |
| Bandwidth | 250 kHz - captures instantaneous phase current in 3-phase motors operating up to 15 kHz PWM frequency. |
| Supply Range | 2.7 V to 5.5 V - compatible with standard 3.3 V and 5 V microcontroller I/O domains without level-shifting. |
| AEC-Q100 Grade | Grade 0 (−40°C to +150°C) - qualified for under-hood automotive applications including engine control and transmission solenoids. |
Pinout & Package
AD8417WBRMZ-10RL uses a 10-lead MSOP package (RM-10) with FMEA-optimized pin layout: NC pins isolate high-voltage inputs (−IN, +IN) from adjacent GND, VREF2, VREF1, and VS to prevent catastrophic failure from PCB trace shorts. Package dimensions: 3.0 mm × 3.0 mm × 1.1 mm, JEDEC MO-187-BA compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | −IN | Negative input terminal for differential shunt voltage sensing; rated for −2 V to +70 V common-mode. |
| 2 | NC | No-connect pin; inserted to electrically isolate −IN from GND and prevent single-point fault propagation. |
| 3 | GND | Analog ground reference; must be low-impedance connection to minimize noise coupling into sensitive inputs. |
| 4 | VREF2 | Reference input pin tied internally to 100 kΩ resistor; used with VREF1 to set output offset voltage ratiometrically. |
| 5 | NC | No-connect pin; isolates VREF2 from OUT to maintain reference integrity during output transient events. |
| 6 | OUT | Buffered voltage output; rail-to-rail capable (0.045 V to VS − 0.035 V), drives 25 kΩ loads directly. |
| 7 | VS | Positive supply input; accepts 2.7 V to 5.5 V; includes internal EMI filtering for robustness in noisy automotive environments. |
| 8 | VREF1 | Reference input pin identical in function to VREF2; both pins must be used together for offset adjustment. |
| 9 | NC | No-connect pin; isolates VREF1 from +IN to prevent fault-induced bias shift on high-side input path. |
| 10 | +IN | Positive input terminal; complements −IN for bidirectional shunt sensing; same voltage rating as −IN. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional current sensing | Configurable output offset (via VREF1/VREF2) enables true zero-centered measurement for forward/reverse motor current. |
| FMEA-tolerant 10-lead MSOP | Strategic NC pins between −IN/GND and +IN/VREF1 prevent short-circuit faults from causing system-level failure in safety-critical automotive designs. |
| PWM common-mode rejection | Patented circuitry suppresses errors from fast-switching (1 V/ns) common-mode transients - validated for 3-phase inverter gate-drive noise immunity. |
| Zero-drift architecture | 0.1 µV/°C typical offset drift ensures stable calibration over lifetime; eliminates need for periodic software offset correction in embedded firmware. |
| AEC-Q100 Grade 0 qualification | Rated for −40°C to +150°C operation with full parameter guarantees - meets ASIL-B functional safety support requirements for motor control subsystems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar current sense amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD8418WBRMZ-10RL | 20 V/V gain, lower bandwidth (200 kHz), same 10-lead MSOP FMEA layout and AEC-Q100 Grade 0 rating. | Better suited for high-current (>100 A), low-gain applications requiring reduced output swing and improved noise immunity. | Select AD8418WBRMZ-10RL when shunt voltage exceeds 150 mV and system prioritizes SNR over dynamic response. |
| INA240A1QDRQ1 | 80 V/V gain, 400 kHz bandwidth, integrated ESD protection, SOIC-8 package (no FMEA NC pins). | Targeted at cost-sensitive industrial motor drives where PCB-level fault tolerance is managed externally. | Choose INA240A1QDRQ1 for higher bandwidth needs and simplified layout, but verify board-level fault isolation separately. |
Compared with AD8417WBRMZ-10RL, AD8418WBRMZ-10RL trades gain and bandwidth for improved noise floor in high-current systems, while INA240A1QDRQ1 offers faster response but lacks the dedicated FMEA pinout - making AD8417WBRMZ-10RL optimal for ASIL-B–compliant automotive H-bridge and solenoid control where fault containment is mandatory.

FAQ
What is the operating temperature range guaranteed for AD8417WBRMZ-10RL?
The AD8417WBRMZ-10RL is specified for −40°C to +150°C operation and qualified to AEC-Q100 Grade 0 standards. All key parameters - including ±400 µV max input offset, 60 V/V gain, and 86 dB CMRR - are guaranteed across this full range, making it suitable for under-hood automotive applications such as engine control modules and transmission valve bodies where ambient temperatures exceed 125°C.
How does the 10-lead MSOP pinout of AD8417WBRMZ-10RL improve functional safety?
The AD8417WBRMZ-10RL uses a purpose-built 10-lead MSOP layout with NC pins inserted between −IN/GND and +IN/VREF1 to physically isolate high-voltage input paths from adjacent low-voltage reference and supply pins. As documented in the datasheet's Pinout Option Engineered for FMEA section, this prevents unrecoverable faults caused by PCB trace shorts - a requirement for ASIL-B–compliant motor and solenoid control systems.
Can AD8417WBRMZ-10RL measure current in both directions, and how is that configured?
Yes, AD8417WBRMZ-10RL supports true bidirectional current sensing. This is achieved by applying complementary voltages to VREF1 and VREF2 - typically tying one to VS and the other to GND to set the output at VS/2 (mid-scale) when differential input is zero. The resulting ±25 A range (with 1 mΩ shunt) enables accurate forward/reverse motor current measurement without polarity reversal hardware.
What is the maximum common-mode voltage AD8417WBRMZ-10RL can withstand continuously?
AD8417WBRMZ-10RL supports a continuous common-mode input voltage range of −2 V to +70 V. This allows reliable high-side sensing in 12 V, 24 V, and 48 V automotive battery systems, including operation during load-dump events (+70 V) and cold-crank conditions (−2 V). The device also survives −3 V to +80 V for short durations per Absolute Maximum Ratings.
Does AD8417WBRMZ-10RL require external components for basic operation?
No, AD8417WBRMZ-10RL operates with only power supply decoupling capacitors. Its integrated EMI filters, zero-drift core, and buffered output eliminate the need for external compensation, filtering, or output op-amps. For bidirectional use, VREF1 and VREF2 are simply tied to VS and GND respectively - no external resistors required - simplifying design and reducing bill-of-materials cost.
