The 8-lead Single Potentiometer devices are pin limited so the SDO pin is multiplexed with the SDI pin
(SDI/SDO pin). After the Address/Command (first 6-bits) are received, If a valid Read command has been
requested, the SDO pin starts driving the requested read data onto the SDI/SDO pin.
The pin’s “smart” pull-up shuts off while the pin is forced low. This is done to reduce the standby and shut-
down current.
The SDO is an open drain output, which uses the internal “smart” pull-up. The SDI input data rate can be
at the maximum SPI frequency. the SDO output data rate will be limited by the “speed” of the pull-up,
customers can increase the rate with external pull-up resistors.
The DFN and QFN packages have a contact on the bottom of the package. This contact is conductively
connected to the die substrate, and therefore should be unconnected or connected to the same ground as
the device’s V
