Product details
Overview
AD8206WYRZ-R7 from Analog Devices is a high common-mode voltage, bidirectional current shunt amplifier optimized for automotive high-side current sensing. It features 20 V/V gain, −2 V to +65 V operating common-mode range, ±4.5 mV offset over temperature, 80 dB CMRR (dc to 20 kHz), and operates from −40°C to +125°C in an 8-lead SOIC package. It enables precise motor control and diesel-injection current monitoring under harsh transients.
For engineers reviewing the AD8206WYRZ-R7 datasheet, AD8206WYRZ-R7 pinout, AD8206WYRZ-R7 application, or AD8206WYRZ-R7 equivalent, this page delivers verified specifications, validated pin functions, automotive-grade thermal performance data, output offset configuration methods, and real-world use cases in transmission and engine management systems.
Technical Context
The AD8206WYRZ-R7 implements a two-stage difference amplifier architecture with precision laser-trimmed resistor networks (matching <0.01%) to achieve >80 dB CMRR from dc to 20 kHz. Its input attenuators scale common-mode voltages by 1/16.7 while preserving differential signals for accurate RTI measurement.
It supports configurable unidirectional or bidirectional operation via VREF1/VREF2 pins, enabling ground-referenced, V+-referenced, or externally referenced outputs - all ratiometric to supply voltage. The Class A output stage delivers 0.08 V to 4.7 V swing into 25 kΩ with 2 Ω output resistance and 0.5 V/µs slew rate.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain | 20 V/V with ±1.2% accuracy over −40°C to +125°C - ensures stable current-to-voltage scaling across full automotive temperature range. |
| Common-Mode Range | −2 V to +65 V continuous - supports direct high-side sensing on 12 V/24 V/42 V battery rails with transient survival to −25 V/+75 V. |
| Offset Drift | 15 µV/°C - minimizes temperature-induced error in closed-loop motor or solenoid control feedback paths. |
| CMRR | 80 dB (dc to 20 kHz) - rejects noise from PWM switching edges and EMI in transmission control modules. |
| Output Voltage Range | 0.08 V to 4.7 V (5 V supply) - provides full-scale headroom for ADC interfacing without external level-shifting. |
| Supply Current | 2 mA - enables low-power operation in always-on vehicle subsystems without thermal derating. |
| Small-Signal Bandwidth | 100 kHz - captures fast current transients during diesel injector actuation or H-bridge commutation. |
Pinout & Package
AD8206WYRZ-R7 is housed in an 8-lead SOIC_N (R-8) package per JEDEC MS-012-AA, with 1.27 mm lead pitch and 5.00 mm × 3.95 mm body dimensions. Pin 4 and Pin 3 are no-connect (NC) terminals; all other pins are electrically active and validated per Analog Devices' metallization diagram and functional descriptions.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| +IN (Pin 8) | Differential input positive | Connects to high-side of shunt resistor; accepts up to +65 V common-mode voltage with 250 mV differential limit. |
| −IN (Pin 1) | Differential input negative | Connects to low-side of shunt; forms precision 20× gain path with +IN; shares same common-mode tolerance. |
| GND (Pin 2) | Analog ground reference | System ground return for internal bias and output stage; not isolated - must be tied to system GND. |
| VREF2 (Pin 3) | Output offset reference input | Paired with VREF1 to set output DC bias; tied to GND for unipolar ground-referenced mode. |
| NC (Pin 4) | No connect | Internally unused; must remain floating - no external connection permitted. |
| OUT (Pin 5) | Amplified output signal | Single-ended 0.08–4.7 V output driving 25 kΩ load; compatible with 12-bit automotive ADCs. |
| V+ (Pin 6) | Positive supply input | Accepts 4.5–5.5 V single supply; absolute max 12.5 V; powers internal amplifiers and bias circuitry. |
| VREF1 (Pin 7) | Output offset reference input | Paired with VREF2; tied to V+ for V+-referenced unipolar mode or split with VREF2 for mid-scale bidirectional offset. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional current sensing | Configurable output offset (0.08–4.7 V) enables true bipolar measurement of forward/reverse motor currents without external op amps. |
| Automotive-grade reliability | Qualified per AEC-Q100; WY grade rated −40°C to +125°C with controlled manufacturing for engine bay and transmission control units. |
| Ratiometric output offset | VREF1/VREF2 divider creates supply-tracking mid-scale point (e.g., 2.5 V at 5 V supply), eliminating need for precision external references. |
| High transient immunity | Survives −25 V to +75 V common-mode transients - meets ISO 7637-2 pulse 5a requirements for 12 V/24 V systems. |
| Low drift performance | 15 µV/°C offset drift and 30 ppm/°C gain drift maintain <1% total error over full temperature range in closed-loop control loops. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side current shunt amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX40056ATA+T | Fixed 20 V/V gain, −4 V to +65 V common-mode, 125°C rating, but only unidirectional output (0–5 V). | Lacks VREF1/VREF2 configurability - cannot support true bidirectional sensing without external circuitry. | Select when cost-sensitive unidirectional sensing suffices and mid-scale offset is unnecessary. |
| INA240A1QDRQ1 | 20 V/V gain, −4 V to +80 V common-mode, 150°C rating, integrated 2.5 V reference, but requires external gain-setting resistors for non-standard gains. | Higher common-mode survival but fixed internal reference limits output offset flexibility vs. AD8206WYRZ-R7's dual VREF pins. | Select when extended −4 V start-up common-mode or AEC-Q100 Grade 0 qualification is required. |
Compared with MAX40056ATA+T and INA240A1QDRQ1, AD8206WYRZ-R7 uniquely combines automotive temperature rating, dual VREF configurability for true bidirectional operation, and proven 80 dB CMRR up to 20 kHz - making it optimal for H-bridge motor control and asymmetric solenoid diagnostics where output polarity reversal is essential.

FAQ
What is the maximum common-mode voltage AD8206WYRZ-R7 can withstand continuously?
AD8206WYRZ-R7 supports continuous operation from −2 V to +65 V common-mode voltage. Its absolute maximum rating allows survival at −25 V to +75 V, meeting ISO 7637-2 pulse 5a requirements for 12 V and 24 V automotive systems. This enables direct connection to battery rails without external level-shifting circuitry.
How does AD8206WYRZ-R7 achieve bidirectional current sensing capability?
AD8206WYRZ-R7 achieves bidirectional sensing through its dual VREF1 and VREF2 pins, which allow precise setting of output DC offset anywhere from 0.08 V to 4.7 V. When configured with VREF1 tied to V+ and VREF2 to GND, the output centers at half-supply (e.g., 2.5 V at 5 V), enabling symmetric positive/negative differential input response.
Is AD8206WYRZ-R7 qualified for automotive applications?
Yes, AD8206WYRZ-R7 is explicitly qualified for automotive use: the "W" prefix denotes AEC-Q100 qualification, and the "Y" grade specifies operation from −40°C to +125°C. It undergoes controlled manufacturing and reliability testing aligned with automotive safety and longevity requirements.
What is the typical output voltage range of AD8206WYRZ-R7 with a 5 V supply?
With a 5 V supply, AD8206WYRZ-R7 delivers a typical output voltage range of 0.08 V to 4.7 V into a 25 kΩ load. This full-scale swing accommodates standard 12-bit automotive microcontroller ADCs without external amplification or attenuation stages.
Can AD8206WYRZ-R7 be used in unidirectional current sensing applications?
Yes, AD8206WYRZ-R7 supports unidirectional operation: tying both VREF1 and VREF2 to GND sets output near 0.08 V at zero differential input (ground-referenced), while connecting both to V+ sets output near 4.7 V (V+-referenced). This flexibility eliminates need for separate unidirectional amplifiers in mixed-signal designs.
