Combined with the 48 µA supply current, this part fits designs where the sense amplifier runs continuously on a battery. ## Active lifecycle and sourcing note For BOM planning, the Zero-Drift series includes multiple gain options (A1 through A5) sharing the same TSOT-23-8 footprint, so a gain change during development does not require a board spin.","metaTitle":"INA190A4IDDFR Zero-Drift Current Sense Amplifier, 33 kHz GBW","metaDescription":"Texas Instruments INA190A4IDDFR Zero-Drift current sense amplifier, 3 µV offset, 48 µA supply, rail-to-rail output.
