Analog Input Protection
Internal protection diodes that clamp the analog input
to AVDD and GND allow the analog input pins to swing
from GND - 0.3V to AVDD + 0.3V without damage.
Analog inputs must not exceed AVDD by more than
50mV or be lower than GND by more than 50mV for
accurate conversions. If an off-channel analog input
voltage exceeds the supplies, limit the input current to
50mA. All analog inputs are also fully ESD protected
to ±8kV, using the Contact-Discharge method and
±15kV using the Air-Gap method specified in IEC-
1000-4-2.
Reference for ADC
Internal Reference
The MAX1233/MAX1234 offer an internal voltage refer-
ence for the ADC that can be set to +1.0V or +2.5V. The
MAX1233/MAX1234 typically use the internal reference
for battery monitoring, temperature measurement, and for
