Single Channel 256 Tap
DP with Integrated
EEPROM and I²C Control
The DP7140 is a single channel non-volatile ïWDS digital
SRWHQWLRPHWHU (DP). This DP is FRPSULVHG of a VHULHs of equal
value UHVLVWRU HOHPHQWV connected between two H[WHUQDOOy
accessible end SRLQWV The WDS SRLQWV between each UHVLVWLYe
HOHPHQt can be selectively connected to the ZLSHU RXWSXW via LQWHUQDO
