LM7321: Output current capability of LM7321

Part Number: LM7321

Hello,

I am using LM7321 (DGK Package 8-Pin VSSOP or SOIC) in one of our designs with below power supply condition.

+15V is connected to Pin#8 of IC and Ground is connected to Pin#4 of IC. 

With this condition, Could you please confirm what is the minimum output current capability for the temperature operating range : 25 degree C-70 degree C.

Thanks

Ganapathi

  • Hi Ganapathi,

    If you look at the last entry of table 7.5 in the datasheet, you'll see information for output current. We guarantee 20mA across temperature for sourcing and 30mA across temperature for sinking. However, please be aware that these are short circuit current limits and are intended as short term events.

    From note (6):
    Applies to both single-supply and split-supply operation. Continuous short circuit operation at elevated ambient temperature can result in
    exceeding the maximum allowed junction temperature of 150°C. Short circuit test is a momentary test. Output short circuit duration is
    infinite for VS ≤ 6 V at room temperature and below. For VS > 6 V, allowable short circuit duration is 1.5 ms.

    What type of circuit are you using the amplifier in? If you provide a little more information on your application, we can assist you further.

    Thanks,
    Paul
