It operates from a 1.6 V to 28 V supply span, making it suitable for both low-voltage portable gear and higher-voltage industrial rails. The -3 dB bandwidth of 125 kHz allows the amplifier to capture DC load currents and low-frequency transients, while the 1.1 µA supply current keeps the quiescent draw negligible in battery-powered designs. ## Package, footprint, and board-fit Available in Tape & Reel (TR) or Cut Tape (CT) for both automated pick-and-place and small-batch assembly. ## Supply range and accuracy considerations With an input offset voltage of 100 µV max, the MAX9938TEBS+TG45 resolves currents down to a few milliamps across a 10 mΩ shunt before the offset dominates the reading. The 125 kHz bandwidth and 1.1 µA supply current represent a deliberate trade-off: the amplifier draws minimal power but its response time (~2.8 µs time constant) limits it to load changes slower than a few hundred kHz. For fast overcurrent detection (sub-microsecond), a comparator-based solution is needed; for average current monitoring in a power rail, this fits. ## Temperature range and compliance Analog Devices lists this part as Active in production, with ROHS3 compliance.","metaTitle":"MAX9938TEBS+TG45 Current Sense Amplifier, 125 kHz, 4-UCSP","metaDescription":"Analog Devices MAX9938TEBS+TG45 current sense amplifier, 1.1 µA supply, 125 kHz bandwidth, 4-UCSP package.
