INA199C2RSWT

Current Regulation/Management Overview

The INA199C2RSWT is a single-channel, bidirectional current sense amplifier from the Texas Instruments INA199 series. It features a gain of 100 V/V and operates with a supply voltage range of 2.7 V to 26 V. The device supports a common-mode voltage range from -100 mV to 26 V. Key electrical specifications include a gain bandwidth product of 30 kHz, a common-mode rejection ratio (CMRR) of 100 dB, an input offset voltage (Vos) of 5 µV, and an input bias current (Ib) of 28 µA. It exhibits a gain error of 0.03% and operates within a temperature range of -40°C to +125°C.

Current Regulation/Management Feature Summary

• Bidirectional current sensing capability for both high-side and low-side monitoring applications
• Zero-drift architecture ensuring high precision with low input offset voltage
• Wide common-mode voltage range supporting operation up to 26 V

Current Regulation/Management Applications

• Battery management systems
• Power supply current monitoring
• Industrial process control

Current Regulation/Management Procurement Notes

Verify the specific suffix 'WT' against the official datasheet to confirm package type and tape-and-reel specifications. Ensure the order matches the required operating temperature range and accuracy class. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and compliance with RoHS standards before finalizing procurement.

Current Regulation/Management Selection Notes

Select this component when bidirectional sensing is required with a maximum common-mode voltage of 26 V. The 100 V/V gain is suitable for detecting small voltage drops across shunt resistors. Consider the UQFN-10 package for space-constrained designs. Verify that the 30 kHz bandwidth meets the signal frequency requirements of the application.

Current Regulation/Management Part Context

This part belongs to the INA199 family of zero-drift current sense amplifiers. It shares architectural similarities with other variants in the series but differs in gain, accuracy grade, and packaging. The RSWR/RSWT suffixes typically denote specific reel or cut-tape packaging options for the UQFN-10 footprint.

Current Regulation/Management Replacement Considerations

INA199C2RSWR: Identical electrical specifications; verify if the 'R' indicates a standard reel while 'T' indicates cut tape, as function remains unchanged.
