INA296B2IDR

Overview

The INA296B2IDR is a bidirectional current sense amplifier from the Texas Instruments INA296B series, housed in an SOIC-8 package. It features a gain of 20 V/V and operates with a common-mode voltage range of -5V to 110V. The device supports a supply voltage between 2.7V and 20V, drawing a typical quiescent current of 2.5mA. Key electrical specifications include a bandwidth of 1.1MHz, a slew rate of 8V/µs, and a maximum gain error of ±0.1%.

Feature Summary

• Supports bidirectional current sensing across a wide common-mode voltage range independent of supply voltage
• Provides high-speed signal processing with a 1.1MHz bandwidth and fast settling time for transient detection
• Delivers precision measurement capabilities through low offset voltage and high common-mode rejection ratio

Applications

• 48V DC/DC converter systems
• 48V battery management systems (BMS)
• Test and measurement equipment
• Macro remote radio unit (RRU) applications
• 48V rack server power supplies

Procurement Notes

Verify the specific suffix ID indicates the SOIC-8 package variant when sourcing. Confirm that the B-series designation aligns with the required accuracy specifications for your design. Ensure compatibility with the -5V to 110V common-mode input requirements of your target application circuit before finalizing procurement.

Selection Notes

Select this component when a fixed gain of 20 V/V is required for bidirectional current monitoring. It is suitable for applications needing operation up to 110V common-mode voltage without exceeding the supply rail limits. Consider the B-series accuracy levels if ultra-precise A-series specifications are not mandatory for the system performance.

Part Context

This part belongs to the INA296x family of ultra-precise, bidirectional current sense amplifiers designed by Texas Instruments. The family offers multiple gain options ranging from 10V/V to 200V/V to optimize output dynamic range. The INA296B series specifically targets applications requiring robust performance with slightly relaxed accuracy tolerances compared to the A-series variants.

Replacement Considerations

INA296A2IDR provides similar functionality with higher precision specifications.
