INA296B1IDGKR

Overview

The INA296B1IDGKR is a bidirectional current sense amplifier from Texas Instruments, featuring a fixed gain of 10V/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 provides a small signal bandwidth of 1.1MHz and a slew rate of 8V/µs. Key electrical specifications include a maximum gain error of ±0.1% and an input offset voltage of ±150µV. It is housed in an 8-pin VSSOP package.

Feature Summary

• Supports bidirectional current sensing across a wide common-mode voltage range independent of the supply voltage
• Delivers high-speed transient detection capabilities through a 1.1MHz bandwidth and fast settling time
• Maintains constant low input bias current throughout the entire common-mode voltage range

Applications

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

Procurement Notes

Verify that the specific part number matches the required gain configuration and package type for your design. Confirm that the component meets all necessary environmental and safety standards for your intended application before finalizing procurement decisions.

Selection Notes

Select this component when a fixed gain of 10V/V is required for high-side, inline, or low-side current sensing applications. It is suitable for designs needing precise measurements over a wide common-mode voltage range without sacrificing signal bandwidth.

Part Context

This device belongs to the INA296x family of ultra-precise current sense amplifiers. The 'B' designation indicates a specific accuracy grade with higher offset voltage and gain error limits compared to the 'A' version, while maintaining identical bandwidth and common-mode performance characteristics.
