Other Parts Discussed in Thread: TDC7200

No info found in datasheet, though urgently needed - what should be the correct "vreg" value of pin 13 of TDC7200 during normal operation ? Thanks!

Sorry this info is a little buried. Section 8.3.1 (page 12 of the TDC7200 data sheet) has this information. Suggested value is 1uF (typical). Thanks, Vishy

Thanks Vishy -

I am actually looking for the voltage level of this pin during normal operation, not the cap value. I need the normal voltage info to debug boards with this chip. Thank you,

DL,

Normal voltage level on this pin should be very close to 1.6V. We don't recommend any external circuitry on this pin except the 1uF decoupling cap. Also, the cap must be present at all times.

Thanks,

Vishy
