TIINA213BIRSWR
Overview
The INA213BIRSWR is a high-side or low-side voltage-output current-shunt monitor designed for precision current sensing. It can sense drops across shunts at common-mode voltages from -0.3V to 26V, independent of the supply voltage. The device is packaged in a tiny 10-pin UQFN, making it ideal for space-constrained power management circuits.
Why Choose This Part
This amplifier offers a low quiescent current of 100uA and a wide common-mode range that extends below ground for low-side sensing. Its 10-UQFN footprint measures only 1.8mm by 1.4mm, providing significant PCB area savings over standard SOIC or SOT packages.
Applications
Key Specifications
Getting Started
To evaluate this part, use a shunt resistor sized for your maximum expected current to keep the differential input within range. Connect the V+ pin to a supply between 2.7V and 26V, and ensure the REF pin is tied to ground or a reference voltage to offset the output. Prototyping typically requires a breakout board due to the 0.4mm pitch UQFN package.
