11 / 54 page Note 2: Electrical specifications are production tested at TA = +25°C. Specifications over the entire operating temperature range are guaranteed by design and characterization. Typical specifications are at TA = +25°C. Note 3: DC accuracy specifications are tested for single-ended ADC inputs only. Note 4: The effective ADC sample rate for port X configured in mode 6, 7, or 8 is: [ADC sample rate per ADCCONV]/(([number of ports in modes 6,7,8] + [1 if TMPSEL ≠ 000]) x [2# OF SAMPLES for port X]) Note 5: See the Recommended VDDIO/VSSIO Supply Selection table for each range. For ports in modes 6, 7, 8, or 9, the voltage applied to those ports must be within the limits of their selected input range, whether in single-ended or differential mode. Note 6: Specification is guaranteed by design and characterization. Note 7: Switch controlled by GPI-configured port. One switch terminal connected to 0V, the other terminal connected to 5V through a 5mA current source. Timing is measured at the 2.5V transition point. Turn-on and turn-off delays are measured from the edge of the control signal to the 2.5V transition point. Turn-on and turn-off durations are measured between control signal transitions. Note 8: In DAC-related modes, the rate, at which PIXI ports configured in mode 1, 3, 4, 5, 6, or 10 are refreshed, is as follows: 1/(40µs x [number of ports in modes 1, 3, 4, 5, 6, 10]) Note 9: Typical (typ) values represent the errors at the extremes of the given temperature range. (VAVDD = 4.75V to 5.25V, VDVDD = 3.3V, VAVDDIO = +12.0V, VAGND = VDGND = 0V, VAVSSIO = -2.0V, VDACREF = 2.5V, VADCREF = 2.5V (Internal), fS = 400ksps, 10V analog input range set to range 1 (0 to +10V). TA = -40°C to +105°C, unless otherwise noted. Typical values are at TA = +25°C.)
