MAX9634: 1mm2 current-sense amplifier sets benchmarks for power consumption and accuracy

The MAX9634 is optimized for compact designs that require precision monitoring. This device consumes an industry-low 1microamp of quiescent current (IQ) to conserve battery life, and it is offered in the smallest package-a tiny, 1mm x 1mm x 0.6mm, 4-bump UCSP(TM), which is 9x smaller than competing SOT23-housed devices. The small size of the MAX9634 is even more impressive when viewed in conjunction with its superior performance. The device features an ultra-low ±250microvolt (max) Vos and 0.5% (max) gain error. This high accuracy simplifies designs, and eliminates the need to worry about worst-case error tolerances.
