Differential amplifier for current sensing
Its 50 kHz gain-bandwidth product and 0.28 V/µs slew rate suit DC and low-frequency AC current measurements, while the 250 µA supply current keeps the power budget lean in always-on systems.
With a 50 kHz gain-bandwidth product, the AD8202YRMZ-R7 is optimized for sensing DC current or ripple up to a few kilohertz. For a gain of 10, the usable bandwidth drops to roughly 5 kHz — adequate for motor current monitoring or battery charge/discharge sensing, but not for switching-frequency ripple above 100 kHz. The 0.28 V/µs slew rate limits large-signal response; expect about 2.8 µs to swing 0.8 V, which is fine for slow control loops but not for fast overcurrent detection.
Supply range and quiescent current
The 3.5 V minimum supply lets the part run from a 3.3 V rail with margin, though the 12 V maximum covers 12 V automotive battery systems. The 250 µA supply current is a key differentiator for battery-powered equipment — it draws less than a tenth of what a general-purpose op-amp might consume, making it suitable for always-sensing nodes in automotive body controllers or industrial remote I/O modules.
Package and footprint
Housed in an 8-MSOP (3.00 mm width) package, the AD8202YRMZ-R7 fits on compact boards where space is tight. The surface-mount package is compatible with standard reflow profiles. Cut Tape (CT) is also available for prototyping.
Lifecycle and compliance
The AD8216YRZ-R7 offers a higher bandwidth (3 MHz) and faster slew rate (15 V/µs) but draws 1 mA supply current, making it a trade-off for speed-sensitive applications.
