  • ALM2402F-Q1: programmable current limit (high side = power supply)

    Resolved
    Part Number: ALM2402F-Q1 Hello, The spec says "RLIMIT = (VS - 1.5) / ILIMIT" This formula is very strange: #1: The current limit would depend on the power supply voltage => not "great" #2: Assuming a VS=10V and ILIMIT=100mA RLIMIT…

  • RE: ALM2402F-Q1: Current Consumption

    The maximum IQ of ALM2402F-Q1 is 5mA per amplifier so for the dual ALM2402F-Q1 the maximum total IQ is 10mA. However, a selection of the LDO to power ALM2402F MUST be based on the max IQ plus maximum load current, Iexc, which is a function of the Vout…
