The 1.7 V to 5.5 V supply span allows operation from a single lithium cell or a regulated 3.3 V/5 V rail, drawing only 48 µA quiescent current — a fit for always-on sensing nodes. ## Parametric Profile for Precision Sensing With a gain-bandwidth product of 35 kHz and a slew rate of 0.3 V/µs, this amplifier is optimized for DC and low-frequency current measurements rather than high-speed transient capture. The 3 µV typical input offset voltage and 500 pA input bias current support accurate shunt-voltage sensing down to microvolt levels without significant zero-error drift. The rail-to-rail output stage maximizes the dynamic range when interfacing with ADCs or comparators that share the same supply rail. Single-circuit topology means one amplifier per package — design in one per shunt channel. ## Sourcing and Compliance Reality Texas Instruments lists the INA190A3IDDFR as active with ROHS3 compliance. Sourced through franchised and independent distribution; availability and current pricing are confirmed at RFQ against your BOM quantity.","metaTitle":"Texas Instruments INA190A3IDDFR Zero-Drift Current Sense","metaDescription":"Texas Instruments INA190A3IDDFR Zero-Drift current-sense amplifier, 35 kHz GBWP, 3 µV offset, SOT-23-8.
