Positive input voltage range - 0 - VDDANA V
Negative input voltage range - 0 - VDDANA
Offset Hysteresis = 0, Fast mode -26 0 26 mV
Hysteresis = 0, Low-Power mode -28 0 28 mV
Hysteresis Hysteresis = 1, Fast mode 8 50 102 mV
Hysteresis = 1, Low-Power mode 14 40 75 mV
Propagation delay Changes for VACM = VDDANA/2 100 mV overdrive, Fast mode - 90 180 ns
Changes for VACM = VDDANA/2 100 mV overdrive, Low-Power mode - 282 534 ns
tSTARTUP Startup time Enable to ready delay Fast mode - 1 3 µs
Enable to ready delay Low-Power mode - 14 23 µs
VSCALE INL (3) - -1.6 0.75 1.6 LSB
DNL (3) - -0.95 0.25 0.95 LSB
Offset Error (1,2) - -0.2 0.26 1.04 LSB
Gain Error (1,2) - -0.89 0.215 2 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.
