76 V common-mode range, single-supply current sense
The LMP8481MM-T/NOPB is a single-channel current sense amplifier from Texas Instruments designed to measure current via a shunt resistor across a 4.5 V to 76 V supply span — covering 12 V, 24 V, and 48 V industrial rails with margin for transients. Its 270 kHz bandwidth means the amplifier can track current transients in motor drives, solenoid actuators, and DC-DC converter outputs, while the 1 V/µs slew rate keeps the output step response clean into a downstream ADC or comparator.
Parametric floor for BOM-fit decisions
Supply current is 88 µA typical — low enough to keep the part on the same 24 V rail that powers the load without a separate regulator, and the 6.3 µA input bias current is drawn from the shunt, so the sense resistor value must be sized to keep the voltage drop above the 80 µV input offset. Packaged in 8-MSOP (0.118" width) and 8-VSSOP — the 3.00 mm body width fits tight channel spacing on a multi-sense board; available in Tape & Reel for production or Cut Tape for prototype builds.
Active status and sourcing posture
Sourced through independent distribution channels; availability and current pricing are confirmed at RFQ against the BOM quantity. No official second-source or pin-compatible equivalent is listed in the manufacturer's cross-reference.
