What are the key features of LMP8481MMX-S/NOPB?
- 76 V maximum common-mode input voltage enables direct high-side current sensing on 48 V and 60 V bus rails
- 100 dB minimum CMRR (124 dB typical) ensures accurate measurements even with large common-mode noise on the supply rail
- Ultra-compact 8-pin VSSOP package with only one external gain-setting resistor network minimizes PCB footprint
- RoHS-compliant lead-free (NOPB) construction for compliance with environmental regulations in industrial and automotive designs
What is LMP8481MMX-S/NOPB used for?
The LMP8481MMX-S/NOPB is designed for high-side current sensing in motor drive controllers, battery management systems, and DC-DC converter feedback loops where common-mode voltages up to 76 V are present. Its high CMRR of 124 dB typical makes it suitable for precision energy metering and overcurrent protection circuits in industrial power supplies. The device also fits compact telecom and server power monitoring applications where board space is critical.

Frequently Asked Questions
What is the maximum common-mode voltage the LMP8481MMX-S/NOPB can handle?
The LMP8481MMX-S/NOPB supports a common-mode input voltage up to 76 V, allowing it to perform high-side current sensing directly on 48 V industrial bus rails and telecom power supplies without requiring additional voltage division or isolation circuitry.
What CMRR does the LMP8481MMX-S/NOPB provide?
The device achieves a minimum CMRR of 100 dB and a typical CMRR of 124 dB, which ensures that large common-mode voltage swings on the power rail produce negligible error at the output, enabling accurate current measurements even in electrically noisy environments.
What is the bandwidth of the LMP8481MMX-S/NOPB current sense amplifier?
The LMP8481MMX-S/NOPB has a 3 dB bandwidth of 270 kHz, which is adequate for monitoring current transients in switching power supplies operating at typical switching frequencies and for detecting overcurrent conditions within microseconds.
What package does the LMP8481MMX-S/NOPB come in?
The device is housed in an 8-pin VSSOP (very thin small-outline package), which offers a very small footprint suitable for space-constrained applications. The MMX suffix indicates the VSSOP package, and S/NOPB indicates it is shipped in tape-and-reel format and is lead-free RoHS compliant.
Can the LMP8481MMX-S/NOPB be used for both high-side and low-side current sensing?
Yes, the LMP8481MMX-S/NOPB can be configured for either high-side or low-side current sensing. High-side sensing is the primary use case given its 76 V common-mode range, but it can also monitor low-side shunt resistors in ground-referenced configurations where its 100 dB+ CMRR rejects any ground offset or noise.
