Its -4-V to 110-V common-mode input range covers high-side and low-side sensing. The 1 MHz bandwidth and 2.5 V/µs slew rate capture current waveforms in switching power supplies and motor drives. The 30 µV input offset voltage keeps readings accurate at millivolt-level shunt drops. ## Supply and temperature — where it fits The amplifier runs on a single supply from 2.7 V to 20 V. The -40°C to 125°C operating range covers automotive and industrial environments. The 1.6 mA supply current keeps total draw modest in multi-channel designs. ## Lifecycle and sourcing reality The INA310B3IDGKR is listed as Active with ROHS3 compliance.","metaTitle":"TI INA310B3IDGKR Current Sense Amplifier, Zero-Drift, 1 MHz","metaDescription":"TI INA310B3IDGKR zero-drift current sense amplifier, -4-V to 110-V common-mode range, 1 MHz bandwidth, 2.5 V/µs slew rate.
