APPLICATIONS

To ease interfacing to most low voltage systems, the

digital output power pins of the ADC10D040 can be

tied to a separate supply voltage of 1.5V to 3.6V,

can be reduced by pulling the PD (Power Down) pin

high, placing the converter into a low power state

standby mode where power consumption is about 30

mW and from which recovery is 800 ns.
