Hello Team,

I have one question about LM6142BIMX Vos@12V DC power supply, what's the max vos spec over temp spec(-40C to 85C)? My customer want to confirm if the max Vos < 3.5mv, please help to check, thanks.

Regards,

Nanfang,

Let's see.
Per data sheet Vos max is 3.3mV at 5V and 4.8mV at 24V, so simple interpolation suggest that 12V is 3.92mV, more specifically -3.92mV < Vos < +3.92mV. Throwing in a little nonlinearity margin, make that +/-4mV

If VCM and Vout are not 6V then CMRR and AVD specs can add to the Vos.
