Current sensor type: ACS758KCB-150B, with 100 μΩ internal conductor resistance
Operating voltage: 3.3-5.5V;
linearity K: 13mV / A;
detectable current (AC or DC) range Ia: -150 ~ 150A;
output voltage formula: = OU1 OU2 = the VCC / 2 + Ia * K = the VCC / 2 + (0.013 V * Ia);
wherein, OU2 is OU1 through the voltage follower output buffer, can tell the microcontroller a / D channel better impedance matching is very suitable for AD conversion.
Working temperature: -40 ~ 125 [deg.] C
