  • OPA347: Comparator application: the risk of keeping switch IN+ and IN-

    TI Thinks Resolved
    Part Number: OPA347 Hi Team, Our schematic as below. OPA347 would output high if MEMS_HEATER pull High. Then the negative feedback would pull low OUT pin. So if MEMS_HEATER maintain High, OPA347 would keeping switch IN+ and IN-. Are there any…
