INA296A5IDR

Overview

The INA296A5IDR is a bidirectional current sense amplifier from Texas Instruments featuring a fixed gain of 200 V/V. 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 typical CMRR of 166dB. Maximum gain error is ±0.01% with a drift of ±1ppm/°C. Input offset voltage is specified at a maximum of ±8µV. It draws 2.5mA quiescent current and is housed in an SOIC-8 package.

Feature Summary

• Ultra-precise bidirectional measurement capability over a wide common-mode voltage range independent of the supply voltage
• High-speed response with 1.1MHz bandwidth and fast settling time for transient detection and overcurrent protection
• Low input bias current that remains constant across the entire common-mode voltage range

Applications

• 48V DC/DC converters
• 48V battery management systems (BMS)
• Test & Measurement equipment
• Macro remote radio units (RRU)
• 48V rack server power supplies

Procurement Notes

Verify the specific suffix ID indicates the SOIC-8 package variant when sourcing. Confirm the A5 designation corresponds to the required 200 V/V gain for your circuit design. Ensure the component meets RoHS standards if applicable to your manufacturing requirements. Cross-reference the datasheet revision date to ensure compatibility with latest application notes.

Selection Notes

Select this part when high precision is required for bidirectional current sensing in high-voltage environments. The 200 V/V gain is suitable for applications utilizing low-value shunt resistors where maximizing output voltage swing is necessary. Consider the 1.1MHz bandwidth for fast transient response needs. Verify that the system supply voltage falls within the 2.7V to 20V operating range.

Part Context

This component belongs to the INA296x family of ultra-precise current sense amplifiers. The 'A' version denotes higher accuracy specifications compared to the 'B' version. The '5' suffix indicates a fixed gain of 200 V/V. The 'IDR' suffix specifies the SOIC-8 surface-mount package. This series is designed for high-side, inline, or low-side sensing applications.

Replacement Considerations

INA296A5IDGKR: Same electrical specifications but in VSSOP-8 package. INA296A5DDF: Same electrical specifications but in SOT-23-8 package. INA296B5IDR: Lower accuracy specifications (±0.1% gain error) in SOIC-8 package.
