s - Channel specific swapping of r invert4_ch IPx is positive the analog input signal for a X X X X <4:1> input e Quad Channel setup. t Channel specific swapping of invert2_ch IPx is positive r the analog input signal for a X X 0x24 <2:1> input Dual Channel setup. e v Channel specific swapping of IPx is positive invert1_ch1 the analog input signal for a X n input single Channel setup. o the IPx pin represents the positive analog input pin, and Inx represents the negative (complementary) input. setting the bits marked invertx_ch<n:1> (individual control for each channel) causes the inputs to be swapped. Inx would then represent the positive input, and IPx the negative input. A / D C Informatio For price, delivery, and to place orders: Analog Devices, Inc., One Technology Way, P.O.
