N-bit resolution

tS + 0.5 + N/2

(9 to 648 cycles in 14-bit

mode)

1. Guaranteed by design.

2. These values are obtained using the following formula: fS = fADC/ tCONV ,

where fADC = 36 MHz and tCONV = 1,5 cycle sampling time + tSAR sampling time.

Refer to the product reference manual for the value of tSAR depending on resolution.

3. Depending on the package, VREF+ can be internally connected to VDDA and VREF- to VSSA.
