Product details

Current sense amplifier for precision low-side/high-side monitoring

The MAX9923FEUB+ is a single current sense amplifier with 0.1 µV input offset voltage, 0.4 V/µs slew rate, and 2.5 kHz bandwidth, operating from -40°C to 85°C.

780 µA supply current — fits always-on and battery-powered rails

Supply current is 780 µA from a 2.85 V to 5.5 V supply. Input bias current is 1 pA.

Package and footprint — 10-uMAX/uSOP, surface mount

The supplier device package is designated 10-uMAX/uSOP. Board layout matches the standard MSOP-10 footprint; no thermal pad is required given the 780 µA dissipation.

Frequently asked questions

What is MAX9923FEUB+'s listed slew rate?

The slew rate is 0.4 V/µs, which limits the amplifier's ability to track fast current transients. For DC or low-frequency monitoring this is adequate; for sub-millisecond fault detection a higher-slew device would be needed.
