INA296B2IDGKR

Overview

The INA296B2IDGKR is a bidirectional current sense amplifier from Texas Instruments featuring a 20V/V fixed gain. It operates with a common-mode voltage range of -5V to 110V and supports a supply voltage between 2.7V and 20V. The device offers a small signal bandwidth of 1.1MHz, a slew rate of 8V/µs, and a maximum gain error of ±0.1%. It is housed in an 8-pin VSSOP package.

Feature Summary

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

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 'B' version designation for accuracy requirements and confirm the 'DGKR' suffix indicates the VSSOP-8 package with reel packaging. Ensure compatibility with system voltage levels and thermal constraints before finalizing procurement specifications.

Selection Notes

Select this component when a fixed 20V/V gain is required for bidirectional sensing. The B version provides higher gain error tolerance compared to the A version. Consider the VSSOP-8 package size and operating temperature range of -40°C to +125°C for integration.

Part Context

This part belongs to the INA296x family of ultra-precise current sense amplifiers. The series includes variants with gains ranging from 10V/V to 200V/V and versions A and B offering different precision levels. The IDGKR suffix specifies the industrial temperature grade and VSSOP-8 surface-mount package.
