It monitors current via a shunt resistor and outputs a single-ended voltage proportional to the sensed current. The Zero-Drift architecture holds input offset voltage to 5 µV, which means you get accurate low-side or high-side current measurement without trimming or calibration — critical for precision motor-phase monitoring, solenoid current regulation, or battery-charge tracking in industrial and automotive environments rated -40°C to 125°C. ## Sourcing and lifecycle — active, no LTB risk The INA310A4IDGKR carries an Active lifecycle status with ROHS3 compliance. No last-time-buy or end-of-life notices are on record. For volume BOM qualification, the part is sourced through independent distribution and quoted to order against an RFQ.","metaTitle":"TI INA310A4IDGKR Zero-Drift Current Sense Amplifier, 900 kHz","metaDescription":"TI INA310A4IDGKR Zero-Drift current sense amplifier, 2.7 V to 20 V supply, 900 kHz bandwidth, 5 µV offset, -40°C to 125°C.
