Dual current-sense amplifier for bidirectional monitoring
It measures current through an external shunt resistor and outputs a voltage proportional to the sensed current, with rail-to-rail output swing. The two independent channels let you monitor two separate current paths — for example, a motor winding and a supply rail — with a single IC, saving board area versus two single amplifiers.
The 350 kHz -3 dB bandwidth covers the switching frequencies of most DC-DC converters and motor drives, letting you capture average current and ripple content without aliasing.
Housed in a 10-VSSOP — the MSOP-10 body is 3.00 mm wide, surface-mount. The small footprint suits space-constrained designs like battery packs, LED drivers, and compact motor controllers. The input bias current is 75 µA, typical for a bipolar-input current-sense amplifier; this flows through the shunt and adds a small offset error that should be accounted for in high-side sensing with large shunt values.
