INA215BIRSWR

Overview

The INA215BIRSWR is a single-channel current sense amplifier from the Texas Instruments INA21x family. It features a fixed gain of 75 V/V and operates with a supply voltage range of 2.7 V to 26 V. The device supports bidirectional measurements with a common-mode voltage range of -300 mV to 26 V. Key electrical specifications include a maximum input offset voltage of 1 µV, an input bias current of 28 µA, and a gain error of 0.02%. It consumes a maximum operating supply current of 100 µA and functions within a temperature range of -40°C to +125°C. The component is housed in a UQFN-10 package.

Feature Summary

• Zero-drift architecture ensures low offset voltage for high-precision sensing
• Bidirectional operation allows measurement of positive and negative currents
• Wide common-mode voltage range independent of supply voltage
• Low power consumption suitable for battery-operated systems

Applications

• Battery management systems
• Overcurrent protection circuits
• Load switch control
• Industrial process controls

Procurement Notes

Verify the specific suffix 'IRSWR' corresponds to the UQFN-10 package and tape-and-reel packaging configuration. Confirm that the 'B' grade designation meets the required offset voltage and gain error tolerances for the application. Ensure compatibility with the intended operating temperature range and check for any moisture sensitivity level requirements during storage and handling.

Selection Notes

Select this component when a fixed gain of 75 V/V is required for shunt-based current monitoring. It is suitable for applications needing wide common-mode voltage coverage up to 26 V. Consider the UQFN-10 package size for space-constrained designs. Verify that the 100 µA supply current fits the system's power budget constraints.

Part Context

This part belongs to the INA21x series of zero-drift current shunt monitors. These devices are designed to measure voltage drops across shunt resistors with high accuracy. The series offers various fixed gains and packages to accommodate different current sensing needs in industrial and consumer electronics.

Replacement Considerations

Check datasheets for other INA21x variants such as INA210, INA211, INA212, INA213, INA214, or INA215 with matching gain and package. Ensure pinout compatibility and verify that alternative parts meet the same electrical specifications and temperature ratings.
