2. Zero-scale allows the wiper to “directly” connect to Terminal B, while full-scale allows the wiper to “directly” connect to Terminal A.
3. There is one R
s
resistor between the maximum wiper value and Terminal A.
4. This current is with the serial interface inactive, and not during an EEPROM write cycle (for non-volatile devices).
5. The serial interface has been tested to 1.8V, the device’s analog characteristics (resistor) have been tested from 2.7V to 5.5V. Review the device’s characterization graphs for information on analog
performance between 1.8V and 2.7V.
6. One of the terminal pins (A or B) is internally connected to ground, due to the limitation of the number of pins on the package.

Low-Voltage Applications
Low-Voltage Applications
Some applications require a low operating voltage. Microchip offers most of the volatile memory devices and some of the
non-volatile devices specified down to 1.8V for their digital operation. The analog performance between 1.8V and 2.7V is
not specified, but is characterized and can be found in the device’s characterization graphs for more information.

6. One of the terminal pins (A or B) is internally connected to ground, due to the limitation of the number of pins on the package.
7. Shutdown support via software (TCON register(s)). If device has SHDN pin, software shutdown also functions.
