LM218-Q1: Output current spec

Part Number: LM218-Q1

Hi,

I want to know about the specifications of the output current.
What is the recommended operating range?
And what is the absolute maximum rating?
It does not have to be a guaranteed value.

Best regards,
Yuto Sakai

    Yuto-san,

    The LM218-Q1 is based on an op amp design originally made in 1976 (maybe earlier) and the data sheet for the Q1 is very sparse. I am curious why you are looking at this device (is it a new design?)

    Output current is rated as VOM at 12V with a 2k load. That is +/-6mA.
    The data sheet schematic shows 25 ohms and 33 ohms and a base emitter junction as the current limits. This is roughly 0.6V/25 ohms = +24mA and -0.6V/33 = 18mA

    Hi,

    Thank you for your reply.
    Although it is a new design, it is used from the previous model.
