INA210AIRSWT

Overview

The INA210AIRSWT is a zero-drift current shunt monitor manufactured by Texas Instruments, housed in a UQFN-10 package. It features a fixed gain of 200 V/V and operates on a single supply voltage ranging from 2.7 V to 26 V. Key electrical specifications include a maximum input offset voltage of 550 nV, an input bias current of 28 uA, and a common-mode rejection ratio of 140 dB. The device supports bidirectional current sensing with a common-mode voltage range up to 12 V. It has a gain bandwidth product of 14 kHz and a typical operating supply current of 100 uA. The component is rated for operation within a temperature range of -40°C to +125°C.

Feature Summary

• Zero-drift architecture ensures high precision with minimal offset voltage drift over temperature.
• Bidirectional sensing capability allows accurate monitoring of current flow in both directions.
• High common-mode rejection ratio provides robust performance in noisy environments.

Applications

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

Procurement Notes

Verify the specific suffix 'AWST' against the official datasheet to confirm package type and temperature grade. Confirm end-of-life status as indicated in distributor records. Ensure compatibility with UQFN-10 footprint requirements during PCB layout. Check RoHS compliance documentation for final assembly verification.

Selection Notes

Select this component when high accuracy is required without external trimming. The fixed 200 V/V gain suits applications requiring significant signal amplification from small shunt voltages. Consider the 12 V common-mode limit relative to system bus voltages. Evaluate the 100 uA supply current against power budget constraints.

Part Context

This part belongs to the INA210 series of current shunt monitors. It shares architectural similarities with other devices in the family but differs in gain and package configuration. The UQFN-10 package offers a compact solution for space-constrained designs compared to larger industrial packages.

Replacement Considerations

INA214AIRSWT offers similar packaging and features but with a different fixed gain of 100 V/V. Verify if the lower gain meets the system's signal conditioning requirements before substitution.
