Abstract

Current sense amplifiers measure differential voltages across a shunt resistor to derive a single-ended output voltage, crucial for current, power, energy calculations in a variety of modern systems. Traditional variations are designed utilizing external shunt resistors to monitor power while our EZShunt™ technology helps integrate shunt functionality and digital conversions, eliminating the need for external components such as resistors and additional ADCs. These advancements not only reduce system complexity and footprint but also enhance precision through advanced calibration techniques that compensate for drift and temperature variations. By evaluating the performance and error characteristics of both traditional and EZShunt™ enabled designs, the data helps provide comprehensive total error specifications inclusive of integrated shunt-related factors for both designs.
