INA186A4IDCKT

Overview

The INA186A4IDCKT is a high-precision, bidirectional current sense amplifier from Texas Instruments. It operates with a supply voltage range of 1.7 V to 5.5 V and supports common-mode voltages from -200 mV to 40 V. The device features a fixed gain of 200 V/V, a gain bandwidth product of 33 kHz, and a typical input offset voltage of -3 µV. Key electrical specifications include a maximum power supply current of 90 µA, an input bias current of 500 pA, and a common-mode rejection ratio of 150 dB. It functions within a temperature range of -40°C to +125°C.

Feature Summary

• Bidirectional sensing capability for accurate measurement in both directions
• High precision performance with ultra-low input offset voltage and bias current
• Supports negative common-mode voltages down to -200 mV

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 prior to integration. Ensure design compatibility with the specified 1.7 V to 5.5 V supply voltage constraints. Validate thermal performance requirements against the -40°C to +125°C operating range. Cross-reference datasheet revisions to ensure parameter consistency.

Selection Notes

Select this component for applications requiring bidirectional current measurement with high accuracy in low-voltage environments. The fixed 200 V/V gain simplifies circuit design by eliminating external resistors. Consider the 90 µA quiescent current for battery-powered designs. The SC-70-6 package offers space-efficient mounting for compact PCB layouts.

Part Context

This part belongs to the INA186 series of zero-drift current sense amplifiers. It shares core architectural features with other variants like the INA186A2IYFDR but differs in gain setting and packaging. The series is designed for high-precision measurements where low drift and high CMRR are critical.
