Typical Applications
AD8210YRZ is suitable for 6 applications: Motor Control, Battery Management, Power Supply Diagnostics, Automotive Load Sensing, Industrial Process Control, Telecom Power Monitoring.
Motor Control
The AD8210YRZ is ideal for motor control applications, particularly in H-bridge and three-phase motor drivers. Its bidirectional current sensing capability allows monitoring of both positive and negative currents, essential for detecting load conditions and implementing closed-loop control. With a common-mode range of -2 V to +65 V, it can handle the high-side and low-side sensing required in motor drives. The 450 kHz bandwidth ensures accurate measurement of fast-switching currents, while the high CMRR of 120 dB rejects noise from the motor's PWM signals. The output can be directly interfaced with ADCs for digital control, and the programmable reference level simplifies offset adjustment. This makes the AD8210YRZ a robust choice for automotive and industrial motor control systems.

Key Differentiators
- High bandwidth of 450 kHz (vs AD8215WYRZ-RL)
- Wide common-mode range of -2 V to +65 V (vs INA199A1DCKR)
- Single-channel design with lower cost (vs AD8216WYRZ-RL)
Design Notes
Place the shunt resistor as close to the AD8210YRZ inputs as possible to minimize parasitic inductance and resistance. Use Kelvin connections to the shunt to ensure accurate voltage sensing. Keep the input traces short and shielded from noisy traces. According to the AD8210 datasheet, proper layout is critical for maintaining high CMRR and bandwidth.
The AD8210YRZ operates from a single 5 V supply. Ensure the supply is well-decoupled with a 0.1 uF ceramic capacitor placed close to the V+ pin. The device draws a typical supply current of 2 mA, so power dissipation is minimal. However, in high-temperature environments, verify that the junction temperature stays within the -40Β°C to +125Β°C operating range.
Do not exceed the absolute maximum ratings, particularly the common-mode input voltage range of -2 V to +65 V. Exceeding this range can damage the device. Also, ensure the output reference pins (REF1 and REF2) are properly configured for the desired output offset. According to the AD8210 datasheet, incorrect reference settings can lead to output saturation.
