Product Overview: INA211BIRSWT from Texas Instruments

The INA211BIRSWT is a precision, low-power current shunt monitor from Texas Instruments, designed to provide high-accuracy measurements in a wide range of applications. This device is part of TI's extensive portfolio of current sense amplifiers that are known for their reliability and performance.

Featuring a common-mode voltage range from -0.3V to +26V, the INA211BIRSWT is capable of monitoring shunt voltage drops across shunts at common-mode voltages that are well beyond the supply voltage. This makes it particularly suitable for battery-powered and automotive applications where the supply voltage may be lower than the shunt voltage.

One of the standout features of the INA211BIRSWT is its precision. With an accuracy of 1%, it ensures precise current measurement which is critical for system performance and efficiency. The device's low offset voltage of 100 µV and gain error of 0.2% further contribute to its high precision, making it an excellent choice for portable devices, power management, and test equipment.

The INA211BIRSWT operates from a single power supply ranging from 2.7V to 26V. This wide supply range, combined with a low quiescent current of 100 µA (typical), makes the device an energy-efficient solution for continuous current monitoring in power-sensitive applications.

Engineered for ease of use, the INA211BIRSWT comes in an ultra-small, leaded SOT-23 package that is easy to integrate into space-constrained designs. Its output is a voltage proportional to the differential input voltage, which means it can be interfaced directly with any typical analog-to-digital converter (ADC) for digital readout of the current.

For designers and engineers looking to implement accurate current sensing in their projects, the INA211BIRSWT offers a balance of precision, power efficiency, and versatility. Whether it's for battery management systems, power supply monitoring, or any application requiring precise current measurement, the INA211BIRSWT from Texas Instruments is a solution that delivers both performance and reliability.
