1. Absolute Maximum Ratings are those values beyond which the life of the device may be impaired.
2. All voltages are measured with respect to GND, unless otherwise specified.
3. Derate above 25 C at the following rates:

RD Mode
INT going Low indicates that the conversion is completed and the data result is in the output latch. INT is reset by
the rising edge of RD or CS (see Figure 1).
Ground
The bottom of resistor ladder, voltage range: GND V
The top of resistor ladder, voltage range: V
CS must be Low in order for the RD or WR to be recognized by the converter.

Overflow output—if the analog input is higher than the V
be used to cascade 2 or more devices to have more resolution (9, 10-bit). It is always active and never becomes
