  • TIDA-010019: Leakage current of diodes

    Resolved
    Part Number: TIDA-010019 Hi team, The reference design has diodes on TC’s signal line, for protection. Would the leakage current of those diodes flow into the ADC input? If yes, would it affect the ADC’s performance? Best regards, Kurum…

  • RE: TMP20: Higher accuracy solutions

    Resolved
    Hi Vencent, For CJC application both the TMP1075 (digital) or the TMP235 (analog) are great solutions. If better accuracy is needed the TMP116 (digital) and TMP117 (digital) can be used. We have a TI Design ( www.ti.com/.../TIDA-010019) that you…

  • RE: TMP235: Junction temp and temperature coefficient

    Resolved
    Hello Yue, That is pure speculation at this point at it depends on the load circuit and the ADC pin current. You can have a look at the reference design for a typical circuit. www.ti.com/.../tida-010019
