It monitors current via an external shunt resistor and outputs a voltage proportional to the sensed current. ## 45 kHz bandwidth — what it means for the loop The 45 kHz gain-bandwidth product sets the usable frequency range for current sensing. For DC or low-frequency load monitoring (battery charge/discharge, motor phase current at low PWM rates), this is adequate. For high-side switching at hundreds of kHz, the bandwidth limits the response — the output will not track fast transients. The 0.3 V/µs slew rate reinforces that this is a precision, not a high-speed, part. ## Package and mounting Surface-mount TSOT-23-8, 8-lead. The small footprint fits tight layouts near the shunt resistor. The supplier device package is TSOT-23-8; the generic package/case is SOT-23-8 — same land pattern, different supplier designator. Both are standard for this class of current-sense amp.","metaTitle":"TI INA190A1IDDFT Current Sense Amplifier, Zero-Drift, 45 kHz","metaDescription":"TI INA190A1IDDFT Zero-Drift current sense amplifier in TSOT-23-8. 45 kHz bandwidth, 3 µV offset, 48 µA supply, -40°C to 125°C.
