  • RE: LM139: Input voltage range limitations not in PSpice model

    Hi John, Since there haven't been any replies to this thread, I will assume we have answered your questions. If you have any further questions, please respond to this thread or open another. Thanks, Joe

  • LM139: Unused pin connection

    • Resolved
    Part Number: LM139 Hi, Could you let me know if below my understanding is correct? In case

  • RE: LM139: Unused Comparator Input Connections

    it is not a serious problem and no damage to the device will occur; the application note just shows the preferred solution to avoid and unnecessary chatter inside the comparator if the inputs are shorted together Chuck

  • LM139: Does TI has an alternate solution similar as LT6703HV-3 (TSOT-23)

  • LM139: IBIS Model

    TI Thinks Resolved
    Part Number: LM139 Hi Team, can you help us confirm if the IBIS Model of this device is available? Thank you.

    Part Number: LM139 Hello, I can't seem to find this info on the datasheet, but what

  • LM139: Output state when one input up to Vcc

    TI Thinks Resolved
    Part Number: LM139 If I’m holding one input at the midpoint by two identical resistors. Like two 1k resistors so the reference level input is 3.3/2 = 1.65V and the other input will swing up and down 0v to 3.3v while Vcc=3.3V, can we guarantee across...

  • LM139: Comparator output seems to be oscillating at lower temperatures

    Part Number: LM139 Hi Team, I would like to ask some help if you can contact the customer offline

  • RE: LM139AQML-SP: PSRR

    Hi Jack, We do not have data for PSRR over frequency. A comparator does not have a linear output like an op-amp, so testing over frequency is VERY, VERY difficult and problematic. The PSRR given is for DC. If we assume the PSRR first pole is also...

  • RE: LM139: Can this comparator work fine if Vsupply=(Vin+) - (Vin-)

    Hi Oleksandr, violating the common mode input voltage range can have an impact on the timing specifications (slow down of comparator switchings and increase of delay times) and can cause other issues. So, it's not recommended to have the input signals...
