Here N = 12 (from 12-bit resolution). tlat(2) Injection trigger conversion latency fADC = 14 MHz - - 0.214 µs -- - 3(4) 1/fADC tlatr(2) Regular trigger conversion latency fADC = 14 MHz - - 0.143 µs -- - 2(4) 1/fADC tS(2) Sampling time fADC = 14 MHz 0.107 - 17.1 µs - 1.5 - 239.5 1/fADC tSTAB(2) Power-up time - 0 0 1 µs tCONV(2) Total conversion time (including sampling time) fADC = 14 MHz 1 - 18 µs - 14 to 252 (tS for sampling +12.5 for successive approximation) 1/fADC 1. Based on characterization, not tested in production. 2. Guaranteed by design, not tested in production. 3. VREF+ is internally connected to VDDA and VREF- is internally connected to VSSA. 4. For external triggers, a delay of 1/fPCLK2 must be added to the latency specified in Table 52. Table 52. ADC characteristics (continued) Symbol Parameter Conditions Min Typ Max Unit Table 53.
