SLVAEW6 December 2020 TPS2661
TPS26610 device only takes a total leakage current less than 20nA from IN and OUT pins and this contributes to an error less than 0.0001% in current measurements of 20mA.Figure 4-3 provides the sum of leakage current from IN and OUT pins of TPS26610 with a voltage of 5V across burden resistor. With TPS26610, it is possible to use a burden resistor of resistance 50 to 249Ω and achieve higher ENOB and lower noise for current measurements.
