What this current-sense amplifier brings to the board
The Texas Instruments INA310B3IDGKR is a zero-drift current-sense amplifier in an 8-VSSOP package. 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 1.6 mA supply current keeps total draw modest in multi-channel designs.
