The rail-to-rail output lets it swing close to the supply, which matters when you're running on a 2.7 V minimum rail and need every millivolt of headroom. The 25 µV input offset keeps the error floor low enough that a 10 mV drop across a 10 mΩ shunt resolves with reasonable accuracy. ## Package and footprint reality The SOT-563 package is small — roughly 1.6 mm x 1.6 mm — so the PCB layout needs tight decoupling placement. The supply pins are close together; a 0.1 µF ceramic right at the pins keeps the 200 µA supply current clean. The 75 µA input bias current is non-negligible for a current-sense amp — it means the shunt resistor value should be chosen so the voltage drop dominates the bias current error, especially at low load currents.","metaTitle":"INA185A4IDRLT Current Sense Amplifier, 105 kHz, SOT-563","metaDescription":"Texas Instruments INA185A4IDRLT current sense amplifier: 2V/µs slew rate, rail-to-rail output, 2.7V to 5.5V supply, -40°C to 125°C.
