Analog Devices Inc. AD8213WYRMZ-RL

Overview

AD8213WYRMZ-RL from Analog Devices is a dual-channel, automotive-qualified 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 for direct ADC interfacing in high-side motor control sensing.

For engineers reviewing the AD8213WYRMZ-RL datasheet, AD8213WYRMZ-RL pinout, AD8213WYRMZ-RL application, or AD8213WYRMZ-RL equivalent, this page delivers verified specifications, validated dual-channel pin mapping, automotive-grade thermal performance data, and real-world current-sensing use cases with design-meaning context.

Technical Context

The AD8213WYRMZ-RL integrates two independent precision amplifiers, each with proprietary offset circuitry and a trimmed 20 kΩ internal filter resistor. Its input stage maintains linearity across 0 mV–250 mV differential input voltage regardless of common-mode voltage (−2 V to +65 V), enabling accurate unidirectional current measurement in noisy automotive power domains.

Each channel features dedicated CF pins for external low-pass filtering prior to amplification-preserving CMRR and avoiding gain error-while the buffered outputs drive 25 kΩ loads with 2 Ω output impedance and 500 kHz small-signal bandwidth.

FAQ

What is the guaranteed common-mode input voltage range for AD8213WYRMZ-RL?

The AD8213WYRMZ-RL guarantees continuous operation from −2 V to +65 V common-mode input voltage. Its survival rating extends to −3 V to +68 V, making it suitable for automotive battery systems subject to load-dump transients and cold-crank conditions. This range is fully validated across the −40°C to +125°C temperature envelope specified for the WY grade.

Does AD8213WYRMZ-RL support bidirectional current sensing?

Yes, AD8213WYRMZ-RL supports bidirectional current sensing through external circuit configuration-typically using one channel for load current and the other for charge current across a shared shunt resistor, as shown in Figure 31 of the datasheet. While it is optimized for unidirectional high-side sensing, its rail-to-rail output and input linearity down to 2 mV enable accurate zero-crossing detection when paired with appropriate reference circuitry.

What is the function of the CF1 and CF2 pins on AD8213WYRMZ-RL?

The CF1 and CF2 pins on AD8213WYRMZ-RL connect to internal 20 kΩ precision-trimmed resistors that form first-order low-pass filters with external capacitors to GND. This architecture filters input noise *before* amplification, preventing noise gain and preserving CMRR-unlike post-amplifier filtering. Typical values range from 20 pF (preserving full 500 kHz bandwidth) to 100 pF (≈8 kHz cutoff), as detailed in the Low-Pass Filtering section of the datasheet.

Is AD8213WYRMZ-RL pin-compatible with other AD8213 variants?

Yes, AD8213WYRMZ-RL shares identical pinout and footprint with all AD8213 variants in the RM-10 MSOP package-including AD8213YRMZ-RL and AD8213WHRMZ-RL. The WY grade differs only in automotive qualification, temperature rating (−40°C to +125°C), and branding (Y2B), with no electrical or mechanical changes affecting PCB layout or interconnect.

What is the maximum output current drive capability of AD8213WYRMZ-RL?

AD8213WYRMZ-RL delivers ±11 mA maximum output source/sink current per channel at room temperature, degrading linearly to ~1 mA at +125°C (per Figure 18 and Figure 19). This supports direct driving of 25 kΩ ADC inputs and RC anti-aliasing networks without external buffers, provided load capacitance remains ≤100 pF to maintain stability and slew rate performance.
