Table 3-3 • Input Resistance of Analog Pads
Pads Pad Configuration Prescaler Range Input Resistance to Ground
AV, AC Analog Input (direct input to ADC) – 2 k (typical)
– > 10 M
Analog Input (positive prescaler) +16 V to +2 V 1 M (typical)
+1 V to +0.125 V > 10 M
Analog Input (negative prescaler) –16 V to –2 V 1 M (typical)
–1 V to –0.125 V > 10 M
Digital input +16 V to +2 V 1 M (typical)
Current monitor +16 V to +2 V 1 M (typical)
–16 V to –2 V 1 M (typical)
AT Analog Input (direct input to ADC) – 1 M (typical)
Analog Input (positive prescaler) +16 V, +4 V 1 M (typical)
Digital input +16 V, +4 V 1 M (typical)
Temperature monitor +16 V, +4 V > 10 M

Maximum Overshoot/
Undershoot

2.7 V or less 10% 1.4 V
5% 1.49 V
3.0 V 10% 1.1 V
5% 1.19 V
3.3 V 10% 0.79 V
5% 0.88 V
3.6 V 10% 0.45 V
5% 0.54 V
Notes:
1. Based on reliability requirements at a junction temperature of 85°C.
2. The duration is allowed at one cycle out of six clock cycle. If the overshoot/undershoot occurs at one out of two cycles,
the maximum overshoot/undershoot has to be reduced by 0.15 V.
