The 690 µA total supply current across all four channels keeps the thermal footprint low in dense boards — each amplifier draws roughly 172 µA, making it suitable for multi-rail monitoring in space-constrained designs. ## Precision floor and input characteristics Input offset voltage is trimmed to 100 µV max, and input bias current sits at 75 µA — the offset dominates the error budget in low-side shunt measurements where the common-mode voltage is near ground, while the bias current matters when the shunt resistance exceeds a few hundred milliohms. ## Package, compliance, and sourcing posture CT suits prototype or low-volume builds.","metaTitle":"Texas Instruments INA4181A1IPWR Current Sense, 350 kHz","metaDescription":"INA4181A1IPWR quad current-sense amplifier, 2V/µs slew rate, 350 kHz bandwidth, 690µA supply, 20-TSSOP.
