TLV1851: differential input resistance

Jens Tyslik
Intellectual 1520 points
Part Number: TLV1851

Hi team, 

in the datasheet of TLV1851 I cannot find any information on the differential input resistance of the device. To be able to compare this parameter to other devices, could you share some information on this? 

Thanks, 
Jens

    Hi Jens,

    Generally speaking, for comparators, the key spec to look is the input bias current as differential input resistance is more of an amplifier spec. Is there a specific reason or use case for this spec other than just comparison? Its sort of rare to apply a voltage differentially when it comes to comparators. I would use the input bias current spec to compare with other devices.
