INA296A5IDGKR

Overview

The INA296A5IDGKR is a bidirectional current sense amplifier from Texas Instruments, housed in an 8-pin VSSOP package. It features a fixed gain of 200V/V and supports a common-mode voltage range from -5V to 110V. The device offers a small-signal bandwidth of 1.1MHz and a slew rate of 8V/µs. Key electrical specifications include a maximum offset voltage of ±8µV, a typical CMRR of 166dB, and a quiescent current of 2.5mA. It operates on a single supply between 2.7V and 20V.

Feature Summary

• Supports bidirectional operation with a wide common-mode input range extending from negative voltages up to 110V.
• Provides high-speed transient detection capabilities through a 1.1MHz signal bandwidth and fast settling time.
• Delivers ultra-precise measurements with low offset voltage and minimal gain error drift across 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 IDGKR corresponds to the VSSOP-8 package configuration required for your PCB layout. Confirm that the A5 variant matches the necessary 200V/V gain setting for your signal conditioning needs. Ensure the design accommodates the specified common-mode voltage limits and supply requirements during integration.

Selection Notes

Select this component when high-side or low-side bidirectional sensing is required at voltages exceeding standard supply rails. The 200V/V gain is suitable for applications utilizing very low-value shunt resistors where maximizing output swing is critical. Consider the thermal resistance characteristics of the VSSOP-8 package for heat dissipation planning.

Part Context

This part belongs to the INA296x family of ultra-precise current sense amplifiers. The 'A' designation indicates the highest precision grade within the series, characterized by tighter offset and gain error tolerances compared to the B version. The '5' suffix specifies the internal fixed gain of 200V/V, distinguishing it from other variants offering gains of 10, 20, 50, or 100V/V.
