Product details

Precision current sensing for industrial and automotive rails

The Texas Instruments INA186A5IDDFT is a Zero-Drift current sense amplifier in a compact SOT-23-8 package. The quiescent current draw is 48 µA, which fits always-on monitoring in battery-operated equipment.

3 µV offset and 500 pA bias — what they mean for measurement accuracy

The 3 µV typical input offset voltage is the Zero-Drift architecture's main advantage: it keeps the error floor low across temperature and time. The 500 pA input bias current matters when the shunt resistor value is high.

Package and temperature grade — board fit and environment

The SOT-23-8 (supplier device package TSOT-23-8) is a surface-mount footprint that fits dense PCB layouts.

Frequently asked questions

What are the typical applications for the INA186A5IDDFT?

As a Zero-Drift current sense amplifier, it is used for precision low-side or high-side current measurement in motor drives, automotive body controllers, battery management systems, power-supply monitoring, and industrial automation. The 45 kHz bandwidth suits DC and low-frequency AC current sensing, while the 48 µA quiescent current fits battery-powered equipment.

Is there a functional equivalent to the INA186A5IDDFT?

The INA254A1IPWAR is a Zero-Drift current sense amplifier in the same family but with a 350 kHz bandwidth and 2.4 V/µs slew rate — a faster option for higher-frequency sensing. The INA4290A2IRGVR is a quad-channel current sense amplifier with 1.1 MHz bandwidth. Neither is a pin-compatible drop-in; the INA186A5IDDFT is the single-channel, low-bandwidth, low-power choice for precision DC measurements.
