INA296B5QDGKRQ1

Overview

The INA296B5QDGKRQ1 is an ultra-precise, bidirectional current sense amplifier from Texas Instruments. It measures voltage drops across shunt resistors over a wide common-mode range of -5V to 110V, independent of the supply voltage. The device features a fixed gain of 200V/V and operates on a single supply voltage between 2.7V and 20V. It offers a small signal bandwidth of 1.1MHz at all gains, with a slew rate of 8V/µs and a step response settling time to 1% of 1µs. The component is AEC-Q100 qualified for Grade 1 automotive applications, supporting an operating temperature range of -40°C to 125°C.

Feature Summary

AEC-Q100 qualified for Grade 1 automotive applications (-40°C to 125°C)
Wide common-mode voltage range from -5V to 110V
High small-signal bandwidth of 1.1MHz at all gain settings
Ultra-precise performance with low offset voltage and high CMRR

Applications

DC/DC converter current monitoring
Battery management systems (BMS)
Fuel cell control units
Smart junction boxes

Procurement Notes

Verify the specific suffix QDGKRQ1 corresponds to the VSSOP-8 package and AEC-Q100 Grade 1 qualification. Confirm that the B5 designation indicates the 200V/V gain setting required for the design. Ensure the source documentation explicitly supports the functional safety capabilities if applicable to the system architecture.

Selection Notes

Select this component when high-side, inline, or low-side bidirectional sensing is required in automotive environments. The 200V/V gain is suitable for applications utilizing very low ohmic shunts where maximizing output dynamic range is critical. Consider the 1.1MHz bandwidth for fast transient detection and overcurrent protection scenarios.

Part Context

This part belongs to the INA296x-Q1 family of ultra-precise current sense amplifiers designed for automotive use. The 'B' variant denotes specific accuracy grades regarding gain error and offset voltage drift compared to the 'A' variant. The 'Q1' suffix confirms automotive qualification, while 'DGKR' specifies the VSSOP-8 package type and reel packaging configuration.
