INA186A1IDCKT

Overview

The INA186A1IDCKT is a single-channel, bidirectional current sense amplifier from Texas Instruments. It features a fixed gain of 50 V/V and operates with a supply voltage range of 1.7 V to 5.5 V. The device supports a common-mode voltage range from -200 mV to 40 V. Key electrical specifications include a maximum input offset voltage of 3 µV, an input bias current of 500 pA, and a gain error of 0.04%. It has a gain-bandwidth product of 45 kHz and consumes 90 µA of operating supply current. The component functions within a temperature range of -40°C to +125°C.

Feature Summary

• Bidirectional sensing capability for accurate current measurement in both directions
• High precision performance with ultra-low input offset voltage and bias current
• Wide common-mode voltage range supporting high-side and low-side configurations

Applications

• Battery management systems
• Industrial process control
• Power supply monitoring

Procurement Notes

Verify the specific suffix IDCKT corresponds to the SC-70-6 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets prior to integration. Ensure the selected grade matches the required offset voltage and gain accuracy specifications for the target application design.

Selection Notes

Select this part for applications requiring bidirectional current monitoring with high accuracy in compact spaces. The SC-70-6 package offers a small footprint suitable for space-constrained designs. Consider the 45 kHz bandwidth and 90 µA quiescent current when evaluating power efficiency and signal response requirements relative to other family members.

Part Context

This component belongs to the INA186 series of zero-drift current sense amplifiers. The series is characterized by high precision and low power consumption. The A1 suffix typically denotes a specific accuracy grade regarding offset voltage and gain error. The IDCKT designation indicates the specific package type and tape-and-reel packaging configuration provided by the manufacturer.

Replacement Considerations

INA186A1IDCKR is a compatible alternative with identical electrical characteristics but supplied in a cut-tape format instead of reel packaging.
