It is not intended for high-frequency switching-current waveforms — that role belongs to parts like the INA254A1IPWAR with its 350 kHz bandwidth. For a motor-drive bus monitor or a telecom line-card current sensor, the 35 kHz corner is adequate and keeps noise from aliasing into the measurement. ## SC-70-6 package — board-area conscious Housed in a 6-pin SC-70 (SOT-363) package with surface-mount termination, this amplifier fits into space-constrained layouts such as battery-pack monitor PCBs, handheld instruments, and sensor modules. The SC-70-6 footprint is common enough that layout libraries and solder-paste stencils are widely available. No special thermal management is needed at 48 µA supply current. The 125°C maximum junction temperature allows placement near hot components like MOSFETs or inductors without derating the supply current.","metaTitle":"INA186A3IDCKR Current Sense Amplifier, Zero-Drift, SC-70-6","metaDescription":"TI INA186A3IDCKR zero-drift current sense amplifier: 1.7 V to 5.5 V supply, 3 µV offset, 48 µA supply current, -40°C to 125°C.

The INA186A3IDCKR provides a fixed gain of 100 V/V, while the INA190 family includes multiple gain options. For a direct replacement, check the gain and bandwidth requirements of your application."},{"question":"Can the INA186A3IDCKR be used as a replacement for the INA186A2IDCKR?","answer":"The INA186A3IDCKR is a gain-option variant within the same INA186 family. The A3 version has a fixed gain of 100 V/V, while the A2 version has a gain of 50 V/V. They are pin-compatible and share the same package and supply range, so the A3 can replace the A2 if the higher gain is acceptable or if the external shunt resistor is adjusted to maintain the same output swing."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/INA186A3IDCKR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/INA186A3IDCKR when reusing this data.
