INA296B4IDDFR

Overview

The INA296B4IDDFR is a bidirectional current sense amplifier from Texas Instruments, featuring a fixed gain of 100 V/V. It operates with a common-mode voltage range from -5V to 110V and supports a supply voltage between 2.7V and 20V. The device offers a bandwidth of 1.1MHz, a slew rate of 8V/µs, and a typical CMRR of 130dB. It utilizes an SOT-23-8 package and functions within a temperature range of -40°C to +125°C.

Feature Summary

• Supports bidirectional current sensing across a wide common-mode voltage range independent of the supply voltage.
• Provides high-speed signal processing capabilities with a 1.1MHz bandwidth and fast settling time for transient detection.
• Delivers precision measurement through low offset voltage and minimal gain error drift over the operating temperature range.

Applications

• 48V DC/DC Converter
• 48V battery management systems (BMS)
• Test & Measurement
• Macro remote radio unit (RRU)
• 48V rack server

Procurement Notes

Verify the specific suffix IDDFR corresponds to the SOT-23-8 package configuration. Confirm that the B4 designation matches the required 100 V/V gain setting for your circuit design. Ensure compatibility with the -5V to 110V common-mode input requirements before finalizing procurement specifications.

Selection Notes

Select this component when high-side, inline, or low-side bidirectional sensing is required at voltages exceeding standard supply rails. The 100 V/V gain is suitable for applications requiring significant amplification of small differential signals. Consider the SOT-23-8 package size constraints and thermal characteristics during PCB layout planning.

Part Context

This part belongs to the INA296x family of ultra-precise current sense amplifiers. The 'B' variant indicates specific accuracy limits compared to the 'A' version, while the '4' suffix denotes the 100 V/V gain option. The IDDFR code specifies the SOT-23-8 surface-mount package type used in compact electronic designs.
