Analog Devices Inc. AD8213YRMZ-RL

Overview

AD8213YRMZ-RL from Analog Devices is a dual-channel, high-voltage current shunt monitor with fixed 20 V/V gain, ±0.25% initial gain accuracy, −2 V to +65 V common-mode input range, and buffered rail-to-rail output voltage (0.05 V to 4.9 V) for direct ADC interfacing in automotive motor controls and battery management systems.

For engineers reviewing the AD8213YRMZ-RL datasheet, AD8213YRMZ-RL pinout, AD8213YRMZ-RL application, or AD8213YRMZ-RL equivalent, this page delivers verified specifications, validated pin functions, confirmed Y-grade (−40°C to +125°C) performance, and real-world current sensing use cases - all extracted from Analog Devices Rev. D datasheet and official ordering guide.

Technical Context

The AD8213YRMZ-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 at any common-mode voltage from −2 V to +65 V, enabling accurate unidirectional current measurement in high-side configurations.

Each channel features dedicated CF pins for external low-pass filtering prior to amplification, preserving CMRR and avoiding gain error. The device operates from a single 4.5 V–5.5 V supply, draws 2.5–3.75 mA total quiescent current, and delivers 500 kHz small-signal bandwidth with 4.5 V/µs slew rate (no CF capacitor).

FAQ

What is the maximum common-mode voltage the AD8213YRMZ-RL can withstand continuously?

The AD8213YRMZ-RL supports a continuous common-mode input voltage range of −2 V to +65 V. Its survival rating extends to −3 V to +68 V, making it suitable for automotive applications subject to load-dump transients. This specification is validated per Analog Devices Rev. D datasheet Table 1 and Absolute Maximum Ratings Table 2, and applies to both channels independently under normal operating conditions.

Does the AD8213YRMZ-RL support bidirectional current sensing?

The AD8213YRMZ-RL is optimized for unidirectional current measurement but can be configured for bidirectional sensing using external reference circuitry - for example, by biasing the inputs to mid-supply and interpreting positive/negative output swings. However, its datasheet specifies guaranteed performance only for 0 mV–250 mV differential input, and dedicated bidirectional parts like AD8210 offer better accuracy and simplified implementation for charge/discharge monitoring.

What is the purpose of the CF1 and CF2 pins on the AD8213YRMZ-RL?

The CF1 and CF2 pins on the AD8213YRMZ-RL connect to internal 20 kΩ precision-trimmed resistors that form first-order low-pass filters with external capacitors to GND. This configuration filters input noise *before* amplification, preventing noise gain and preserving CMRR and accuracy - unlike post-amplifier RC filtering, which degrades signal-to-noise ratio. The corner frequency is calculated as f_3dB = 1/(2π × 20 kΩ × C_F).

Is the AD8213YRMZ-RL qualified for automotive applications?

Yes - the AD8213YRMZ-RL is the commercial-grade variant, but Analog Devices also offers the AD8213WYRMZ-RL (W-grade), which is explicitly qualified for automotive applications per AEC-Q100 and manufactured under controlled processes for enhanced reliability. While AD8213YRMZ-RL shares identical electrical specs and package, only W-grade models are certified for automotive use; designers must select AD8213WYRMZ-RL or AD8213WHRMZ-RL for production automotive systems.

What is the output voltage range of the AD8213YRMZ-RL at room temperature?

At 25°C and with a 5 V supply, the AD8213YRMZ-RL delivers an output voltage range of 0.05 V (low) to 4.9 V (high) for each channel. This rail-to-rail buffered output is specified in the Rev. D datasheet Table 1 under "Output Voltage Range Low/High" for AD8213Y/AD8213WY grades and enables direct interfacing with standard 5 V ADCs without level-shifting circuitry.
