Product details
Overview
AD8213YRMZ-R7 from Analog Devices is a dual-channel, high-voltage current shunt monitor with fixed 20 V/V gain, ±0.5% max gain error over −40°C to +125°C, −2 V to +65 V common-mode input range, and buffered rail-to-rail output voltage compatible with 5 V ADCs. It enables precision unidirectional current sensing in automotive motor controls and engine management systems using a single 5 V supply.
For engineers reviewing the AD8213YRMZ-R7 datasheet, AD8213YRMZ-R7 pinout, AD8213YRMZ-R7 application, or AD8213YRMZ-R7 equivalent, key selection criteria include guaranteed CMRR ≥100 dB at dc, input offset drift ≤±12 µV/°C, dual-channel independent filtering via CF1/CF2 pins, and MSOP-10 packaging qualified for automotive-grade thermal cycling and ESD robustness.
Technical Context
The AD8213YRMZ-R7 integrates two matched, high-precision instrumentation amplifiers with proprietary offset circuitry and internal 20 kΩ filter resistors. Each channel delivers 20 V/V gain with <0.5% total error across temperature and maintains linearity for differential inputs up to 250 mV regardless of common-mode voltage (−2 V to +65 V).
Its input stage rejects common-mode transients without requiring external level-shifting, while CF1/CF2 pins enable low-pass filtering before amplification-preserving CMRR and eliminating gain error from external RC networks. The buffered outputs drive 25 kΩ loads with 2 Ω impedance and support 500 kHz small-signal bandwidth.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain | 20 V/V fixed, ±0.5% max error over −40°C to +125°C - eliminates calibration overhead in production test. |
| Common-Mode Range | −2 V to +65 V continuous - supports direct high-side sensing on 12 V/24 V/48 V battery rails without attenuation. |
| Input Offset Drift | ±12 µV/°C max - ensures stable zero-current baseline in under-hood automotive environments. |
| CMRR | 120 dB typical at dc, ≥100 dB min - rejects battery ripple and switching noise in motor control feedback loops. |
| Supply Voltage | 4.5 V to 5.5 V - compatible with standard 5 V logic and ADC reference domains. |
| Quiescent Current | 3.75 mA max per amplifier (7.5 mA total) - enables low-power operation in always-on vehicle subsystems. |
| Bandwidth | 500 kHz small-signal −3 dB - captures PWM edge dynamics in solenoid and inverter current monitoring. |
| ESD Rating | ±4000 V HBM - meets automotive component-level ESD immunity requirements per ISO 10605. |
Pinout & Package
AD8213YRMZ-R7 is housed in a 10-lead Mini Small Outline Package (MSOP, RM-10), 3.0 mm × 3.0 mm × 1.1 mm, with exposed pad for thermal enhancement and RoHS-compliant matte tin lead finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (−IN2) | Inverting input, Channel 2 | Connects to shunt resistor low-side terminal for high-side current sensing; high-impedance node minimizes loading error. |
| 2 (+IN2) | Noninverting input, Channel 2 | Connects to shunt resistor high-side terminal; common-mode voltage tolerance up to +65 V enables direct battery connection. |
| 3 (GND) | Analog ground reference | Single-point return for both channels and filter capacitors; must be tied to system power ground with low-inductance path. |
| 4 (OUT2) | Buffered output, Channel 2 | Rail-to-rail voltage output (0.05 V to 4.9 V) directly interfaces with SAR or sigma-delta ADCs without level-shifting. |
| 5 (CF2) | Filter capacitor terminal, Channel 2 | Connects external capacitor to GND to form 20 kΩ–C low-pass filter; preserves CMRR and avoids gain error from external RC. |
| 6 (CF1) | Filter capacitor terminal, Channel 1 | Independent filtering path for Channel 1; enables differential noise rejection in multi-shunt systems (e.g., motor phase A/B). |
| 7 (OUT1) | Buffered output, Channel 1 | Electrically isolated from OUT2; supports simultaneous dual-current measurement (e.g., load + recirculation current). |
| 8 (V+) | Positive supply | Accepts 4.5 V–5.5 V; supplies both amplifiers and output buffers; decoupling capacitor required within 1 cm. |
| 9 (+IN1) | Noninverting input, Channel 1 | High-side shunt connection point; identical specs to +IN2 - supports redundant or differential shunt configurations. |
| 10 (−IN1) | Inverting input, Channel 1 | Low-side shunt connection point; matched input impedance (5 kΩ diff, 5 MΩ CM >5 V) ensures channel-to-channel tracking. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar current sense amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX40056AUB+T | Single-channel, 50 V max common-mode, 100 kHz bandwidth, ±1.5% gain error. | Limited to lower-voltage, lower-bandwidth applications; lacks dual-channel integration and automotive qualification. | Choose when cost-sensitive single-channel sensing suffices and 65 V common-mode range is unnecessary. |
| INA240A1QDRQ1 | Single-channel, 80 V common-mode, 4 V/V gain, ±0.2% gain error, integrated 2.5 V reference. | Requires external gain scaling for 20× output; no built-in filter resistors; higher quiescent current (1.8 mA vs. 3.75 mA per channel). | Prefer for ultra-high-precision single-shunt systems where programmable gain and reference stability outweigh dual-channel needs. |
Compared with MAX40056AUB+T and INA240A1QDRQ1, AD8213YRMZ-R7 uniquely delivers dual-channel 20× gain, 65 V common-mode tolerance, and integrated filter resistors in an automotive-qualified MSOP package-reducing BOM count and layout complexity in multi-shunt automotive subsystems.

FAQ
What is the maximum common-mode input voltage supported by the AD8213YRMZ-R7?
The AD8213YRMZ-R7 supports a continuous common-mode input voltage range of −2 V to +65 V, with survival capability up to −3 V to +68 V. This allows direct high-side sensing on 12 V, 24 V, and 48 V automotive battery rails without external attenuation or level-shifting circuitry. The specification is validated across the full −40°C to +125°C operating temperature range for the Y grade.
Does the AD8213YRMZ-R7 require external resistors for gain setting?
No, the AD8213YRMZ-R7 features factory-trimmed internal gain-setting resistors providing a fixed 20 V/V gain with ±0.5% maximum error over temperature. No external resistors are needed for gain configuration, simplifying layout and eliminating drift sources associated with discrete resistor networks. This fixed gain is integral to the AD8213YRMZ-R7's architecture and cannot be modified.
Can the AD8213YRMZ-R7 be used for bidirectional current sensing?
Yes, the AD8213YRMZ-R7 can be configured for bidirectional current sensing by connecting the shunt resistor between the +IN1/−IN1 and +IN2/−IN2 pairs and biasing the outputs with external references. Figure 31 in the AD8213 datasheet shows a dual-channel implementation where Channel 1 monitors load current and Channel 2 monitors charge current. However, the AD8213YRMZ-R7 itself is optimized for unidirectional measurement; dedicated bidirectional parts like the AD8210 offer better zero-crossing accuracy.
What is the purpose of the CF1 and CF2 pins on the AD8213YRMZ-R7?
The CF1 and CF2 pins on the AD8213YRMZ-R7 connect to internal 20 kΩ precision-trimmed resistors that form first-order low-pass filters with external capacitors to ground. This filtering occurs before amplification, preventing noise amplification while preserving CMRR and gain accuracy. Typical values range from 20 pF (for full 500 kHz bandwidth) to 100 pF (for ~8 kHz cutoff), as specified in the AD8213YRMZ-R7 theory of operation section.
Is the AD8213YRMZ-R7 qualified for automotive applications?
Yes, the AD8213YRMZ-R7 is part of the Y grade, which is qualified per AEC-Q100 for automotive applications with operating temperature range −40°C to +125°C. While the W-grade variants (e.g., AD8213WYRMZ-R7) carry explicit "automotive" branding and enhanced reliability reporting, the AD8213YRMZ-R7 shares identical electrical specifications, MSOP-10 packaging, and manufacturing controls - making it suitable for non-safety-critical automotive subsystems including body control modules and HVAC actuators.
