ELECTRICAL CHARACTERISTICS (continued)
(VDVDDIO = +5V, VAVDD = +3.3V; VDVDD = +2.5V, system clock (fSYSCLK) = 16MHz, burst frequency (fBURST) = bandpass frequency
(fBPF) = 50kHz, CREFBG = CREF = 1F in parallel with 0.01F, fADCCLK = 2MHz (SAR data rate = 125ksps), TA = TMIN to TMAX, unless
otherwise specified. Typical values are at TA = +25°C.)
