Product details
Overview
AD8202YRMZ-R7 from Analog Devices is a single-supply, high common-mode voltage difference amplifier optimized for automotive current sensing. It delivers 20× system gain, ±2 mV initial input offset (RTI), 80 dB minimum CMRR from dc to 10 kHz, and operates across −40°C to +125°C - enabling precise shunt-based battery line monitoring in transmission control and diesel injection systems.
For engineers reviewing the AD8202YRMZ-R7 datasheet, AD8202YRMZ-R7 pinout, AD8202YRMZ-R7 application, or AD8202YRMZ-R7 equivalent, this page provides verified technical context, package-specific performance data, functional block-level design meaning, and automotive-grade selection guidance aligned with SOIC-8 packaging and AEC-Q100-relevant operation.
Technical Context
The AD8202YRMZ-R7 implements a two-stage architecture: a dynamic bridge preamplifier (A1) with ×10 gain and 100 kΩ output impedance, followed by a ×2 buffer (A2) with 2 Ω output resistance. Its input network attenuates differential signals while extending the common-mode range to −6 V to +28 V at 5 V supply - enabling direct connection to battery rails above VS or below GND.
CMRR is maintained via matched resistor networks and an internal compensator (A3) that actively reduces common-mode voltage at A1's inputs. The externally accessible 100 kΩ node between A1 and A2 supports low-pass filtering and gain adjustment without bandwidth degradation, making it suitable for noise-sensitive current sensing in engine management and adaptive suspension control.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| System Gain | 20× fixed composite gain (A1 ×10, A2 ×2); enables full-scale output from small shunt voltages (e.g., 100 mV input → 2 V output). |
| Common-Mode Voltage Range | −6 V to +28 V at 5 V supply; supports direct sensing on 12 V/24 V battery lines, including negative transients and overvoltage events. |
| Input Offset Voltage (RTI) | ±2 mV max at TOPR; ensures ≤10 mV total error in 500 mV full-scale current sense applications before trimming. |
| CMRR | ≥80 dB from dc to 10 kHz; rejects battery ripple and switching noise in high-noise powertrain environments. |
| Supply Voltage Range | 3.5 V to 12 V; compatible with automotive 5 V and 3.3 V logic domains while tolerating load-dump conditions up to 12.5 V. |
| Operating Temperature | −40°C to +125°C; qualified for under-hood deployment in transmission control units and engine ECUs. |
| Bandwidth | 30 kHz min system bandwidth; sufficient for closed-loop control of solenoids, fuel injectors, and motor drivers. |
Pinout & Package
AD8202YRMZ-R7 is packaged in an 8-lead SOIC (Small Outline Integrated Circuit) with exposed pad, rated for −40°C to +125°C operation and compliant with AEC-Q100 Grade 1 requirements.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (−IN) | Inverting input of preamplifier A1 | Accepts differential signal from low-side shunt; referenced to common-mode voltage up to +28 V or down to −6 V. |
| 2 (GND) | Analog ground reference | Return path for internal biasing; must be connected to system power ground to maintain CMRR and offset stability. |
| 3 (A1) | Preamplifier A1 output node | High-impedance (100 kΩ) output used for external RC filtering or gain adjustment; not buffered. |
| 4 (A2) | Inverting input of buffer A2 | Receives filtered/preconditioned signal from Pin 3; 100 kΩ source impedance requires matched layout to minimize offset drift. |
| 5 (OUT) | Final buffered output | Rail-to-rail capable (0.04 V to 4.8 V at 5 V supply); drives ADC inputs or comparator thresholds directly. |
| 6 (+VS) | Positive supply input | Accepts 3.5 V–12 V; PSRR ≥75 dB ensures immunity to supply rail noise in noisy automotive environments. |
| 7 (NC) | No connect | Internally unconnected; must remain floating per datasheet to avoid parasitic coupling or latch-up. |
| 8 (+IN) | Noninverting input of preamplifier A1 | Accepts differential signal from high-side shunt; matches −IN in impedance and common-mode tolerance. |
Key Features
| Feature | Design Value |
|---|---|
| High common-mode input range | −6 V to +28 V at 5 V supply enables direct battery-line sensing without level-shifting or isolation. |
| Externally adjustable gain | 100 kΩ A1 output node allows gain reduction (e.g., ×10) or increase (up to ×50) using passive resistors - no redesign needed. |
| Integrated low-pass filter node | Pin 3 provides access to pre-buffer signal for 1-pole or 2-pole RC filtering - suppresses PWM noise before final amplification. |
| Automotive temperature qualification | Specified from −40°C to +125°C in SOIC package; meets AEC-Q100 stress test requirements for engine bay deployment. |
| Low input offset drift | ±10 µV/°C max offset vs. temperature ensures stable zero-current baseline across thermal cycles in transmission control. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar difference amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| INA199A1DCKR | Single-stage architecture; 50 V/V fixed gain; 2.7 V–26 V supply; ±100 µV offset; no external filter node. | Limited to lower common-mode ranges (−4 V to +26 V); lacks A1 output access for gain tuning or filtering. | Preferred for cost-sensitive, fixed-gain 12 V systems where board space is constrained and gain flexibility is unnecessary. |
| MAX4080FASA+ | Current-sense amplifier with integrated 20 kΩ sense resistor; 20× gain; 4.5 V–76 V supply; ±150 µV offset. | Designed for high-side sensing only; no true differential input; not rated for −40°C to +125°C automotive operation. | Suitable for industrial 24 V/48 V DC systems requiring integrated shunt, but not for AEC-Q100-compliant automotive designs. |
Compared with INA199A1DCKR and MAX4080FASA+, the AD8202YRMZ-R7 uniquely combines extended common-mode tolerance (−6 V to +28 V), external gain/filter node access, and full automotive temperature qualification - making it the only option among the three qualified for under-hood transmission and engine control use cases.

FAQ
What is the maximum continuous common-mode voltage the AD8202YRMZ-R7 can withstand?
The AD8202YRMZ-R7 supports a continuous common-mode voltage range of −6 V to +28 V when operated at a 5 V supply. Absolute maximum ratings allow transient input voltages up to 44 V for 400 ms, and continuous input voltage up to 35 V - making it suitable for 12 V and 24 V automotive battery monitoring with robust fault tolerance.
Can the AD8202YRMZ-R7 be used with a 3.3 V supply?
Yes, the AD8202YRMZ-R7 operates across a supply range of 3.5 V to 12 V. At 3.3 V, the device remains functional but the guaranteed common-mode range narrows slightly; datasheet characterization confirms stable operation down to 3.5 V, so 3.3 V use requires validation of output swing and CMV margin in the target application.
Does the AD8202YRMZ-R7 have built-in ESD protection?
The AD8202YRMZ-R7 incorporates internal ESD protection structures rated per JEDEC JS-001 Class 2 (2 kV HBM). The datasheet specifies ESD caution for handling, and recommends standard PCB-level protection (e.g., TVS diodes) for high-energy transients in automotive harness environments - especially on pins exposed to battery lines.
How does the 100 kΩ resistor at Pin 3 affect system bandwidth?
The 100 kΩ resistor at Pin 3 (A1 output) forms a programmable interface point: adding capacitance creates a 1-pole low-pass filter whose cutoff frequency is fc = 1/(2πRC). Bandwidth remains unaffected by gain adjustments using this node because filtering occurs before the ×2 buffer stage - preserving signal integrity while suppressing high-frequency noise.
Is the AD8202YRMZ-R7 pin-compatible with other members of the AD8202 family?
Yes, all AD8202 variants - including AD8202YRMZ-R7 (SOIC-8), AD8202WYRMZ-R7 (automotive-grade SOIC-8), and AD8202ARMZ-R7 (MSOP-8) - share identical pinouts and electrical functionality. Differences lie in qualification level (AEC-Q100 Grade 0 vs. Grade 1), temperature range limits, and screening - not pin assignment or interface behavior.
