Analog Devices Inc. AD8215WYRZ

Overview

AD8215WYRZ from Analog Devices is a high-voltage, unidirectional current shunt monitor with fixed 20 V/V gain, ±0.3% max gain error over −40°C to +125°C, −2 V to +65 V common-mode input range, and buffered output for direct ADC interfacing in automotive high-side current sensing.

For engineers reviewing the AD8215WYRZ datasheet, AD8215WYRZ pinout, AD8215WYRZ application, or AD8215WYRZ equivalent, this part supports precision motor control, engine management, and transmission systems where survival up to +68 V common-mode and ±4000 V HBM ESD robustness are required.

Technical Context

The AD8215WYRZ uses a proprietary input stage architecture that maintains linearity across 0 mV–250 mV differential input voltage regardless of common-mode voltage (−2 V to +65 V), enabling accurate current measurement during PWM switching transients in solenoid and motor drives. Its internal gain-setting resistors are trimmed to 0.01% matching, delivering stable 20 V/V gain without external calibration.

It features rail-to-rail output swing (0.1 V to 4.9 V at +125°C) into 25 kΩ load, 450 kHz small-signal bandwidth, and 4.5 V/µs slew rate - optimized for fast transient response in closed-loop current regulation. Input bias current remains below 1 µA across full common-mode range, minimizing shunt error in low-current detection.

FAQ

What is the guaranteed common-mode voltage range for AD8215WYRZ in automotive operation?

The AD8215WYRZ guarantees −2 V to +65 V common-mode input voltage range across its full −40°C to +125°C operating temperature range. This specification is validated under automotive-grade test conditions and supports battery-referenced high-side sensing in 12 V and 24 V systems, including transient conditions such as load dump and cold crank.

Does AD8215WYRZ require external gain-setting components?

No, AD8215WYRZ does not require external gain-setting components. It integrates a precision-trimmed 20 V/V gain amplifier with internal resistors matched to 0.01%, delivering ±0.3% maximum gain error over temperature. This eliminates calibration steps and layout sensitivity associated with external resistor networks in production ECUs.

How does AD8215WYRZ handle low common-mode voltages near 0 V?

The AD8215WYRZ maintains full linearity and specified accuracy down to −2 V common-mode voltage, including operation at 0 V. Its proprietary input stage ensures <0.1% total output error across 0–250 mV differential input even at VCM = 0 V, enabling reliable current measurement during PWM off-states and low-battery cranking conditions.

Is AD8215WYRZ pin-compatible with other members of the AD8215 family?

Yes, AD8215WYRZ shares identical 8-lead SOIC_N (R-8) pinout and electrical behavior with AD8215YRZ and AD8215YRZ-R7. The "W" suffix denotes automotive qualification with controlled manufacturing, but pin assignment, function, and interface logic are fully identical - enabling drop-in replacement in existing designs requiring AEC-Q100 compliance.

What is the maximum differential input voltage the AD8215WYRZ can withstand without damage?

The AD8215WYRZ has an absolute maximum continuous differential input voltage rating of 0.5 V, as specified in Table 2 of the Rev. B datasheet. Exceeding this value may cause permanent damage. For transient overload protection, the device recovers in <1 µs from differential overloads up to 250 mV, as verified in Figures 15 and 16.
