AD7352 DRIVING DIFFERENTIAL INPUTS Differential operation requires V and V IN+ simultaneously with two equal signals that are 180° out of phase. Because not all applications have a signal preconditioned for differential operation, there is often a need to perform ...
Page 15
MODES OF OPERATION The mode of operation of the AD7352 is selected by controlling the logic state of the CS signal during a conversion. There are three possible modes of operation: normal mode, partial power- down mode, and full power-down ...
Page 16
AD7352 FULL POWER-DOWN MODE Full power-down mode is intended for use in applications where throughput rates slower than those in partial power- down mode are required because power-up from a full power- down takes substantially longer than that from a ...
Page 17
POWER-UP TIMES The AD7352 has two power-down modes: partial power-down and full power-down, which are described in detail in the Normal Mode, Partial Power-Down Mode, and Full Power- Down Mode sections. This section deals with the power-up time required when ...
