 Hi, I was wondering if I have a 30mA current getting into the In+ of LTC2508 in a long period of time, e.g. three months, would LTC2508 features be affected in anyways? e.g. the dynamic range?

  • The In+ input (See Figure 3 of the data sheet.) goes straight into a 45pF capacitor except for protection diodes that are normally reverse biased. The only way to draw any significant current into the input is to take the input voltage above REF or below ground. Exceeding REF or ground by more than 300mV exceeds the absolute maximum ratings for the LTC2508-32.
