Vcm for LMC6041IN

 Dear Technical Support Team,

 

Can LMC6041IN accept ±1.5V with ±5V supply?

Datasheet shows Absolute Maximum Ratings below.


Differential Input Voltage ±Supply Voltage

Supply Voltage (V+ − V−) 16V



But I couldn't find Vcm range. Maybe CMR is a kind of Vcm on LMC6041IN datasheet.

If it is true, it doesn't shows minus side of Vcm on V-.

Best Regards,

y.i

    Hello Y.i.,

    The maximum input would be 2.3V below V+, so with a ±5V supply, the input range would be -5.1V to +2.7 at room temperature, or -5 to +2.6 over temperature.

    So, yes, a ±1.5V input on a ±5V supply is possible.

    Regards,
