1. Resistor options are: -202 (2.1 k), -502 (5.0 k), -103 (10.0 k), and -503 (50.0 k).
2. Resistor options are: -502 (5.0 k), -103 (10.0 k), 503 (50.0 k), and -104 (100.0 k).
3. Zero-scale allows the wiper to “directly” connect to Terminal B, while full-scale allows the wiper to “directly” connect to Terminal A.
4. There is one R
S resistor between the maximum wiper value and Terminal A.
5. This current is with the serial interface inactive, and not during an EEPROM write cycle (for non-volatile devices).
6. 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.
7. 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.
8. Shutdown support via software (TCON register(s)). If device has SHDN pin, software shutdown also fuctions.
9. High voltage command support is for compatibility with the corresponding non-volatile version of the device.
