Table 33-20. Electrical and Timing (Device Variant A)
Symbol Parameter Conditions Min. Typ. Max. Units
Positive input voltage range 0 - VDDANA V
Negative input voltage range 0 - VDDANA
Offset Hysteresis = 0, Fast mode -15 0.0 +15 mV
Hysteresis = 0, Low power mode -25 0.0 +25 mV
Hysteresis Hysteresis = 1, Fast mode 20 50 80 mV
Hysteresis = 1, Low power mode 15 40 75 mV
Propagation delay Changes for VACM=VDDANA/2
 100mV overdrive, Fast mode - 60 116 ns
Changes for VACM=VDDANA/2
 100mV overdrive, Low power mode - 225 370 ns
tSTARTUP Startup time Enable to ready delay
Fast mode - 1 2 μs
Enable to ready delay
Low power mode - 12 19 μs
VSCALE INL (3) -1.4 0.75 +1.4 LSB
DNL (3) -0.9 0.25 +0.9 LSB
Offset Error (1,2) -0.200 0.260 +0.920 LSB
Gain Error (1,2) -0.89 0.215 0.89 LSB
Note:
  1. According to the standard equation V(X) = VLSB * (X + 1); VLSB = VDDANA / 64.
  2. Data computed with the Best Fit method.
  3. Data computed using histogram.
