Its 1.3 MHz bandwidth and 2.5 V/µs slew rate support switching-frequency monitoring in motor drives and power converters. The 55 µV input offset voltage, combined with the zero-drift architecture, keeps measurement error low even at small shunt drops, which matters when sizing the sense resistor for minimal power loss. ## Supply range and temperature grade The amplifier operates from 2.7 V to 20 V single supply, covering common 3.3 V, 5 V, and 12 V rails. The -40°C to 125°C ambient temperature range suits industrial and automotive under-hood environments where the part might sit near a motor or solenoid. The 8-VSSOP package (3.00 mm width) fits dense layouts, but the small footprint means the thermal dissipation relies on the PCB copper — keep the sense resistor away from the package if the shunt current is high. ## Sourcing and lifecycle RoHS3 compliant. If you are qualifying this for a new BOM, the active status means no near-term supply disruption.","metaTitle":"TI INA310B2IDGKR Current Sense Amplifier, 1.3 MHz","metaDescription":"TI INA310B2IDGKR zero-drift current sense amplifier: 1.3 MHz bandwidth, 55 µV offset, 2.7–20 V supply.
