Description

Logic Power Supply Input. The voltage supplied at this pin determines the voltage at which the interface

operates. This pin should be decoupled to ground. The voltage range on this pin is 1.65 V to 3.6 V and may be less

than the voltage at VDD but should never exceed it by more than 0.3 V.

Power-Down Pin. This pin places the part into full power-down mode and enables power conservation when operation

is not required. This pin can be used to reset the device by toggling the pin low for a minimum of 1 ns and a maximum

of 100 ns. If the maximum time is exceeded, the part enters power-down mode. When placing the AD7298-1 into full

power-down mode, the analog inputs must return to 0 V.

The exposed metal paddle on the bottom of the LFCSP package should be soldered to PCB ground for proper

functionality and heat dissipation.
