AD CONVERTER, CONTROL METHOD OF AD CONVERTER, AND CONNECTION METHOD OF AD CONVERTER

摘要

PROBLEM TO BE SOLVED: To provide an AD converter the power consumption of the output interface of which can be reduced by providing an output current value setting circuit and to provide a control method and a connection method thereof.;SOLUTION: The AD converter 101 includes: an output current value setting register 30 for latching a register value transmitted from a host device; and the output current value setting circuit 31 for controlling a constant current source 21 of a low voltage differential signal output circuit 2 to specify an output current on the basis of a register value latched in the output current value setting register 30. Thus, decreasing the output current value depending on the mount state can reduce the power consumption.;COPYRIGHT: (C)2007,JPO&INPIT
