Shutdown
Shutdown allows the resistor network to be disconnected
from the circuit. This can substantially reduce the current
of the system. In the MCP42XXX devices, when the SHDN
pin is low, Terminal A is disconnected from the resistor
network and Terminal W is connected to Terminal B. When
the device enters “Shutdown” mode, the current path from
Terminal A to Terminal B is opened. This minimizes the
system current. Also the wiper is forced to be connected
to Terminal B. This is to force that node to a known state
so that system power consumption can be minimized.
Product Specifications
Note 1: Zero-scale allows the wiper to “directly” connect to Terminal B, while full-scale allows the wiper to “directly” connect to Terminal A.

Digital Potentiometer Solutions
2: There is one RS resistor between the maximum wiper value and Terminal A.
3: This current is with the serial interface inactive, and not during an EEPROM write cycle (for non-volatile devices).
4: 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.
