The 100 µV input offset voltage sets the floor for shunt voltage: with a 10 mΩ sense resistor, a 10 A current yields 100 mV across the shunt, giving a 0.1 % error from VOS alone. ## Active production — no LTB pressure It is supplied in Tape & Reel (TR) or Cut Tape (CT) options on a 7-inch reel, compatible with standard pick-and-place assembly. ## 4-UCSP footprint — layout constraints The 4-bump CSP package measures 1 mm x 1 mm, which demands a tightly controlled PCB pad pattern and a solder-paste stencil with 0.25 mm apertures to avoid bridging. Surface-mount assembly requires a 0.50 mm pitch between bumps; the small size means the sense resistor and bypass capacitor must be placed within 2 mm of the package to minimise parasitic inductance.","metaTitle":"MAX9634TERS+T Current Sense Amplifier – nanoPower, 1.1 µA","metaDescription":"Analog Devices MAX9634TERS+T nanoPower current sense amplifier: 1.1 µA supply, 125 kHz GBP, 100 µV VOS, 4-UCSP (1x1) package.
