Hi Devin , Thank you For the Quick Response , i did try modified various Such as ACQ Time , ADC Frequency , even SET SOC15 (Internal Temperature ) to by trigger by PWM (like the Other SOC0..4 ) , and remove the software trigger . 1. i still get the felling that there is some influence between sequential sampling 2.I did some testing which include Connecting BLDC Motor to unit (the product is BLDC Driver ) and measuring the current IS,IT on SOC0 - ADCA , SOC0- ADCB and we have additional motor control that we can control and it's current is measured IS,IT SOC1-ADCA , SOC1-ADCB , to this axis not motor was connected. the order of the sampling is (MOTOR #1 (IS-SOC0_ADCA, IT-SOC0_ADCB) and then MOTOR #2 (IS-SOC1_ADCA , IT-SOC1_ADCB) a.when motor was connected ON AXIS #1 it has some influence ON AXIS#2 (up to ~ 12 ADC point ) , it is correlated with the current (Sine wave) b.when we connected the Motor to AXIS#2 and move it , there was no direct influence on AXIS#1 for this i guess the influence can be only sequential ( SOC0 -> SOC1 ) but not the other way around . i then change the CODE so the sampling would reverse e.g. MOTOR #2 IS,IT (SOC0-ADCA , SOC0-ADCB) MOTOR #1 IS,IT (SOC1-ADCA , SOC1-ADCB) and did the same testing as before , there is some sequential influence only (e.g SOC0--affect >SOC1 ) can you advice on this matter ? (i have Increase S+H to 511 ~ 1.5us , the ADC Pin has 200pf Capactior ) , and Motor current is fed trough OP-AMP
