It measures the voltage drop across a shunt resistor and outputs a rail-to-rail voltage proportional to the load current. ## Where it fits in a design This part is built for high-side or low-side current sensing. The rail-to-rail output means the amplifier can swing its output close to the supply rails, preserving dynamic range when the shunt voltage is small. The -40°C to 125°C operating temperature covers industrial motor drives, outdoor telecom equipment, and automotive under-hood modules. The 48 µA supply current makes it a candidate for always-on monitoring in battery-powered systems — a fuel-gauge front end, for example, or a solar charge controller that needs to log current around the clock. ## Package and mounting The TSOT-23-8 package (supplier device package TSOT-23-8) is a surface-mount footprint. It is small enough for space-constrained PCBs but still hand-solderable with a fine tip. ## Lifecycle and sourcing The INA190A2IDDFR is listed as Active and ROHS3 compliant. No end-of-life notice or last-time-buy window is in effect. It is sourced through independent distribution and quoted to order against an RFQ.","metaTitle":"INA190A2IDDFR Current Sense Amplifier, Zero-Drift, 37 kHz","metaDescription":"TI INA190A2IDDFR zero-drift current sense amplifier, 37 kHz GBW, 48 µA supply, rail-to-rail output, TSOT-23-8.
