Product details
Overview
AD8202YRMZ 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 −6 V to +28 V common-mode range at 5 V supply - enabling precise shunt-based current measurement in battery-supply lines and engine control units.
For engineers reviewing the AD8202YRMZ datasheet, AD8202YRMZ pinout, AD8202YRMZ application, or AD8202YRMZ equivalent, this page provides verified technical context, package-specific specifications, functional pin definitions, automotive-grade performance metrics, and validated alternative options for transmission control, diesel injection, and adaptive suspension systems.
Technical Context
The AD8202YRMZ implements a two-stage architecture: a ×10 preamplifier with dynamic bridge topology rejects common-mode signals up to ±28 V while preserving differential inputs, followed by a ×2 output buffer with 2 Ω output resistance. Its externally accessible 100 kΩ resistor at Pin 3 enables configurable low-pass filtering and gain adjustment without bandwidth degradation.
Designed for harsh automotive environments, it features −40°C to +125°C operation, 3.5 V to 12 V supply range, 30 kHz system bandwidth, and 0.28 V/μs slew rate. The SOIC-8 package (YRMZ suffix) supports die-level trimming for ±0.3% gain error and ±10 μV/°C offset drift over temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| System Gain | 20× fixed; enables direct amplification of mV-level shunt voltages to full-scale ADC input ranges |
| Common-Mode Range | −6 V to +28 V at 5 V supply; supports operation above battery rail and below ground in 12 V/24 V automotive systems |
| CMRR | ≥80 dB dc–10 kHz; maintains accuracy despite large transients on power rails during load dump or cranking |
| Input Offset (RTI) | ±2 mV max; limits baseline error in zero-current detection for fault diagnostics |
| Supply Range | 3.5 V to 12 V; compatible with wide-input automotive regulators and brownout conditions |
| Operating Temperature | −40°C to +125°C; qualified per AEC-Q100 for under-hood engine management applications |
| Bandwidth | 30 kHz typical; sufficient for real-time monitoring of PWM-driven solenoids and motor currents |
Pinout & Package
AD8202YRMZ is housed in an 8-lead SOIC package (YRMZ = RoHS-compliant SOIC_N). The package meets JEDEC MS-012AC, with 1.27 mm pitch, 4.9 mm × 3.9 mm body, and 1.75 mm max height. Thermal resistance θJA = 120°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (−IN) | Inverting input terminal | Accepts negative-side shunt voltage; part of matched attenuator network for CMR enhancement |
| 2 (GND) | Analog ground reference | Return path for internal biasing; must be tied to low-impedance system ground near shunt |
| 3 (A1) | Preamplifier output node | Externally accessible 100 kΩ series point for LPF capacitor or gain-adjust resistor placement |
| 4 (A2) | Buffer amplifier input | High-impedance input (40 nA bias) accepting filtered preamp signal; shorted to Pin 3 for default gain |
| 5 (OUT) | Final buffered output | Rail-to-rail capable (48 mV to 4.8 V at 5 V); drives ADCs or comparator inputs directly |
| 6 (+VS) | Positive supply input | Accepts 3.5–12 V; PSRR ≥75 dB ensures immunity to supply ripple in noisy engine bays |
| 7 (NC) | No-connect terminal | Internally unconnected; must remain floating - no external tie or pull-up/pull-down |
| 8 (+IN) | Non-inverting input terminal | Accepts positive-side shunt voltage; matched to Pin 1 for balanced CM rejection |
Key Features
| Feature | Design Value |
|---|---|
| Extended common-mode range | Operates with inputs −6 V to +28 V relative to GND - supports high-side sensing in 12 V/24 V battery systems |

| Automotive qualification | AEC-Q100 Grade 1 compliant; specified for −40°C to +125°C ambient with 150°C junction capability |
| Low input offset drift | ±10 μV/°C max over temperature; ensures stable zero-current baseline across engine thermal cycles |
| Configurable gain | Gain adjustable from <10× to >50× via external resistors on Pins 3/4 or feedback loop - no redesign needed |

Equivalent & Alternatives
The following parts are listed as comparable options for similar difference amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| INA240A1QDRQ1 | Bi-directional current sense amp; 80 V common-mode range; 120 kHz bandwidth; integrated 20× gain | Supports bidirectional current flow and higher CMV; requires external filter for noise-sensitive analog inputs | Preferred for 48 V EV systems needing reverse-current detection and wider bandwidth |
| LT6105IMS8#PBF | Single-supply current sense amp; 60 V CMV; 1.5 MHz bandwidth; 0.5 mV offset; SO-8 package | Higher speed and lower offset but limited to −5 V to +60 V CMV; not AEC-Q100 qualified | Suitable for industrial motor drives where automotive qualification is not required |
Compared with AD8202YRMZ, INA240A1QDRQ1 offers broader CMV and bidirectional capability but lacks the AD8202YRMZ's configurable gain node and automotive-optimized offset drift; LT6105IMS8#PBF delivers superior speed and offset but omits AEC-Q100 compliance and extended low-temperature performance.

FAQ
What is the maximum continuous common-mode voltage the AD8202YRMZ can withstand?
The AD8202YRMZ 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. This makes AD8202YRMZ suitable for direct connection to automotive battery rails including load-dump and cranking events. Exceeding +28 V or −6 V continuously risks parametric degradation.
Can the AD8202YRMZ be used for bidirectional current sensing?
No - the AD8202YRMZ is unidirectional. Its input stage and internal architecture are optimized for single-polarity differential signals referenced to the shunt's high side or low side, but it does not support true bidirectional measurement like the INA240 series. For applications requiring current direction detection (e.g., regenerative braking), AD8202YRMZ must be paired with external circuitry or replaced with a bidirectional alternative.
How is gain adjusted on the AD8202YRMZ, and what is the minimum achievable gain?
Gain is adjusted by adding external resistors to Pin 3 (A1 output) and Pin 4 (A2 input). Connecting a resistor from Pin 3/4 to GND lowers gain; with REXT = 100 kΩ, gain reduces to ×10. The minimum practical gain is ~×5, limited by noise and offset contributions. AD8202YRMZ does not support gain reduction below ×5 without significant SNR penalty.
Is the AD8202YRMZ pin-compatible with other members of the AD820x family?
No - AD8202YRMZ uses an SOIC-8 footprint with specific pin functions (e.g., Pin 3 = A1 output, Pin 4 = A2 input). AD8201 and AD8203 use different pinouts and gain architectures. Substituting AD8202YRMZ into an AD8201 design would require PCB layout changes and recalibration due to differing internal routing and external node access.
Does the AD8202YRMZ require external passive components for basic operation?
Yes - AD8202YRMZ requires at minimum a 0.1 µF bypass capacitor between +VS and GND, placed within 1 cm of the device. For stable operation in noisy automotive environments, a second 10 µF tantalum or ceramic capacitor is recommended. No external resistors are needed for default ×20 gain, but Pin 3 must be shorted to Pin 4 via PCB trace or 0 Ω resistor.
