Description
Logic Power Supply Input. The voltage supplied at this pin determines at the voltage at which the interface
operates. This pin should be decoupled to GND. The voltage range on this pin is 1.65 V to 3.6 V and may be less
than the voltage at 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 in 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.
