Typical Applications
AD8210YRZ is suitable for 6 applications: Motor Control, Battery Monitoring, 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 drivers where bidirectional current sensing is required. Its wide common-mode range of -2 V to +65 V allows it to monitor current on both high-side and low-side of the motor. The 450 kHz bandwidth ensures accurate measurement of dynamic currents during motor startup and stall conditions. The high CMRR of 120 dB rejects common-mode noise from PWM switching, providing clean current feedback for closed-loop control. The device's 5 mA output capability can directly drive an ADC or comparator for overcurrent protection.

Battery Monitoring
In battery monitoring systems, the AD8210YRZ accurately measures charge and discharge currents. Its bidirectional capability allows it to detect both charging and discharging currents with a single device. The wide common-mode range accommodates battery voltages up to 65 V, making it suitable for automotive and industrial battery packs. The low supply current of 2 mA minimizes power consumption, which is critical for battery-powered systems. The programmable output reference level enables easy interfacing with ADCs for digital monitoring.
Recommended
Power Supply Diagnostics
The AD8210YRZ is used in power supply diagnostics to monitor load currents and detect faults. Its high CMRR ensures accurate current measurement even in the presence of large common-mode voltages from the power supply. The device's input filter reduces high-frequency noise, providing stable readings. The 450 kHz bandwidth allows detection of fast current transients, which is essential for overcurrent protection. The 5 mA output can drive a comparator to trigger a shutdown signal in case of overcurrent conditions.
Recommended
Automotive Load Sensing
In automotive applications, the AD8210YRZ monitors currents in various loads such as lights, motors, and solenoids. Its wide common-mode range of -2 V to +65 V is compatible with automotive battery voltages, including load dump conditions. The operating temperature range of -40Β°C to +125Β°C meets automotive requirements. The bidirectional capability is useful for detecting both forward and reverse currents in actuators. The device's small SOIC package is suitable for space-constrained automotive modules.
Recommended
Industrial Process Control
The AD8210YRZ is used in industrial process control to monitor currents in actuators, heaters, and other equipment. Its high CMRR and wide common-mode range make it robust in industrial environments with high electrical noise. The 450 kHz bandwidth allows real-time monitoring of fast-changing currents. The device's programmable output reference level enables easy calibration for different current ranges. The 5 mA output can drive long cables to a central control unit without significant signal degradation.
Recommended
Telecom Power Monitoring
In telecom power systems, the AD8210YRZ monitors currents in -48 V power distribution. Its common-mode range of -2 V to +65 V covers the -48 V rail, allowing high-side sensing. The bidirectional capability is useful for detecting both supply and return currents. The device's low supply current and small package make it suitable for high-density telecom boards. The 450 kHz bandwidth enables monitoring of transient currents during system startup.

Key Differentiators
- Wide common-mode range of -2 V to +65 V (vs INA282AIDR)
- Bidirectional current sensing (vs INA240A1DR)
- High CMRR of 120 dB (vs AD8215WYRZ-RL)
Design Notes
Place the shunt resistor close to the AD8210YRZ inputs to minimize parasitic inductance and resistance. Use Kelvin connections to the shunt to ensure accurate voltage sensing. Keep the input traces short and shielded if possible to reduce noise pickup.
The AD8210YRZ operates from a 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 only 2 mA, so power dissipation is minimal, but proper decoupling is essential for stable operation.
Do not exceed the absolute maximum ratings, including the common-mode input range of -2 V to +65 V. Exceeding these limits can damage the device. Also, ensure the output load does not exceed 5 mA, as this can cause output saturation or damage.
Compliance Information
RoHS compliant per distributor data. AEC-Q100 not applicable as this is not an automotive-qualified part.
