It converts the voltage across an external shunt resistor into a rail-to-rail output, with a gain bandwidth product of 35 kHz and a slew rate of 0.3 V/µs. The zero-drift architecture holds input offset voltage to 3 µV, keeping measurement accuracy stable across the -40°C to 125°C operating range. Supply current sits at 48 µA, making this part a fit for battery-powered or energy-harvesting designs where every microamp matters. Typical applications include low-side and high-side current sensing in power management, motor control, and industrial load monitoring. ## What the ratings mean for your BOM The 3 µV input offset voltage keeps measurement error low across temperature. The 48 µA supply current is the quiescent draw.","metaTitle":"TI INA190A3IDCKR Current Sense Amplifier, Zero-Drift, 35 kHz","metaDescription":"TI INA190A3IDCKR Zero-Drift current sense amplifier, 35 kHz bandwidth, rail-to-rail output, 48 µA supply, SC-70-6.

This lets a downstream ADC use the full input range without a level shifter."},{"question":"Is INA190A3IDCKR available via RFQ confirmation?","answer":"Stock and pricing are confirmed at quote time. Submit an RFQ for current availability and a firm quote through independent distribution."},{"question":"What are alternatives to INA190A3IDCKR?","answer":"For a wider bandwidth and higher slew rate in the same Zero-Drift current sense family, consider the INA254A1IPWAR (350 kHz, 2.4 V/µs, TSSOP package). For a general-purpose rail-to-rail op-amp, the TLV9351IDCKR offers 3.5 MHz bandwidth and 20 V/µs slew rate, but it is not a dedicated current sense amplifier."},{"question":"Can INA190A3IDCKR be used for high-side current sensing?","answer":"Yes. The common-mode voltage range extends to the supply rail, and the rail-to-rail output allows the signal to swing to the ADC input. The zero-drift topology keeps offset drift low across temperature, which is important for accurate high-side measurements where the shunt voltage is small."},{"question":"Is INA190A3IDCKR obsolete?","answer":"No. The product status is Active, with no announced discontinuation.
