TLV1872: Maximum input signal frequency

Lionel Will

Part Number: TLV1872

Tool/software:

Hello,

we are trying to evaluate if the TLV1872 is suitable for our application and can't seem to find definite information about the maximum frequency of its input signal.

Will we encounter any problems when applying a +/-5V sinusoidal signal with 30kHz to it?

Thank you for your support!

Hi Lionel,

Clemens provided an estimation of how to determine the toggle frequency of a comparator.

TLV1872 has a typical 65ns propagation delay, so I don't see any issues with it handling a 30kHz input signal. Please make sure that VCCI/VEEI and VCCO/VEEO are both configured within the recommended operating conditions.
