Hi Experts,

Good day.

Can you teach/tell us how to identify the VIL, VIH, and IOL of the device TLV320AIC20IPFB.

These information are not available from D/S, upon checking.

Thank you.

Regards,

Hi,

Consider these as logic level detections, above VIH input is considered high and below VIL it is considered low etc.

Maybe this training video can help.

Hello Peter,

Thank you for responding.

I should have described the query further. I know what are these parameters meant for (VIL, VIH, and IOL). What we are asking are the ranges of these levels with respect to Vdd, also on how to determine the source output current at low level (IOL), specifically to the TLV320AIC20IPFB device.

These values are present to other audio codec's D/S but not on this one.

Thank you for your guidance,

Regards,
Archie A.

These VIL and VIH are normally 0.3 and 0.7 of VDD. There's no IOL for this device.
