LT1054: What's the tolerance of Vout?

Pearl Lin

Part Number: LT1054

Hi engineers,

I have question on Vout tolerance.

I saw the Vout max to be -15V on product page.

But it shows Vout max -5.2V in the datasheet.

Which spec is correct?

Thanks.

    Hi Pearl,

    The engineer supporting this device is out of the office and will be back Tuesday.

    Thanks,

    The LT1054 works as an inverter, so any input voltage of up to 15 V will be output as a voltage of up to −15 V.

    The value in table 6.5 is not the maximum that could be reached under any possible condition, but applies only to the test condition specified in the second column and in footnote (3). In particular, the R1/R2 feedback divider configures a nominal output voltage of −5 V (like in figure 11).
