INA296A5QDRQ1

Overview

The INA296A5QDRQ1 is a bidirectional current sense amplifier from Texas Instruments, designed for high-precision measurements in automotive and industrial environments. It operates with a common-mode voltage range of -5 V to 110 V, independent of supply voltage. The device features a gain of 100 V/V, a bandwidth of 1.1 MHz, and a CMRR of 150 dB. It functions on a single supply between 2.7 V and 20 V, consuming 2.5 mA. Packaged in an SOIC-8, it meets AEC-Q100 standards for automotive applications.

Feature Summary

• Supports bidirectional current sensing across a wide common-mode voltage range of -5 V to 110 V
• Delivers high precision with low input offset voltage and minimal gain error
• Provides fast transient response with a 1.1 MHz signal bandwidth

Applications

• Automotive battery management systems
• High-side or low-side current monitoring
• Overcurrent protection circuits

Procurement Notes

Verify the specific suffix QDRQ1 confirms the SOIC-8 package and AEC-Q100 qualification. Ensure the 'A' grade designation matches required accuracy specifications. Confirm moisture sensitivity levels and reflow soldering profiles align with assembly capabilities. Cross-reference the manufacturer part number against official TI documentation to avoid counterfeit components.

Selection Notes

Select this component when precise bidirectional measurement is required in high-voltage environments. The 100 V/V gain suits applications needing significant signal amplification. Consider the SOIC-8 package for standard surface-mount layouts. Evaluate thermal performance within the specified operating temperature range.

Part Context

This device belongs to the INA296-Q1 family of ultra-precise current sense amplifiers. It shares core architecture with other variants differing primarily in gain settings and package types. The series targets demanding automotive applications requiring robust performance under varying electrical conditions.

Replacement Considerations

INA296A4QDRQ1 offers 100 V/V gain in the same package. INA296A3QDRQ1 provides 50 V/V gain. Verify pin compatibility and gain requirements before substitution.
