  • MSP430I2041: Input voltage range of SD24 pins

    Resolved
    Part Number: MSP430I2041 Tool/software: Hello, I believe SD24 input pins (A0.0+, A0.0-, A1.0+, A1.0-, A2.0+, A2.0-, A3.0+, A3.0-) 's input voltage range is AVSS to VCC = -1V to VCC. But another pins allow minumum -0.3V. I believe reason of this…
