TLC14: TINA model for TLC14

Laszlo Garab

Part Number: TLC14

Hello,

I am thinking of filtering 1kHz square wave to sine, but I have no experince with the filters and have no special instruments to test it. Will be a TINA model available to test imagination before invest much effort in this circuit? TINA could give me some idea about THD and so on.

Regards,

LAszlo

Hi Laszlo,

I'm sorry but, we do not have any models for the TLC14. What sort of THD are you looking for?

Hello Tom,

I mean THD as Total Harmonic Distortion as a qualifier of sinewave after filtering the square wave. I am interested in what is happening in the filtering process and how "clean" is the sinewave I have received.

Hi Laszlo,

The immediate 'Filter Out' signal from pin 5 is going to have some remnants of the switched capacitor/clock on it so you'd have to do some additional filtering on the output to get good THD numbers.
