INA296A4IDDFR

Overview

The INA296A4IDDFR is a bidirectional current sense amplifier with a fixed gain of 100 V/V. It operates over a common-mode voltage range of -5V to 110V and supports a supply voltage from 2.7V to 20V. The device features a bandwidth of 1.1MHz, a slew rate of 8V/µs, and a maximum gain error of ±0.01%. It is housed in an SOT-23-8 package.

Feature Summary

• Ultra-precise bidirectional operation with high common-mode rejection ratio
• Wide common-mode input range independent of supply voltage
• High-speed response suitable for transient detection and fast protection

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 variant. Confirm that the 'A' designation matches the required ultra-precision specifications, specifically the ±0.01% gain error and ±10µV offset voltage limits. Ensure the application environment remains within the specified -40°C to +125°C operating temperature range.

Selection Notes

Select this component when a fixed 100 V/V gain is required for high-side or low-side sensing. The wide common-mode range allows operation beyond the local supply voltage. Consider the 1.1MHz bandwidth for applications requiring rapid overcurrent detection. Verify that the output swing requirements fit within the 2.7V to 20V supply constraints.

Part Context

This part belongs to the INA296x family of ultra-precise current sense amplifiers. The 'A' suffix indicates the highest precision grade with minimal drift. The '4' designates the 100 V/V gain option. The 'IDDFR' suffix specifies the SOT-23-8 surface-mount package and tape-and-reel shipping configuration.

Replacement Considerations

INA296A4DDFR: Same electrical specifications but in SOIC-8 package. INA296A4DGKT: Same electrical specifications but in VSSOP-8 package. These are pin-compatible package alternatives.
