Analog Input Protection
Internal protection diodes which clamp the analog input
to VDD and GND allow the analog input pins to swing
from GND - 0.3V to VDD + 0.3V without damage. Both
inputs must not exceed VDD by more than 50mV or be
lower than GND by more than 50mV for accurate conver-
sions. If an off-channel analog input voltage exceeds
the supplies, limit the input current to 2mA.
Internal Clock
The MAX1086–MAX1089 operate from an internal oscilla-
tor, which is accurate within 10% of the 4MHz specified
clock rate. This results in a worse case conversion time
of 3.7s. The internal clock releases the system micro-
processor from running the SAR conversion clock and
allows the conversion results to be read back at the
processor’s convenience, at any clock rate from 0 to
8MHz.
