Non-Demultiplexed DIV1 ModeThe MAX104 may be operated at up to 500Msps in non-demultiplexed DIV1 mode (Table 2). In this mode, theinternal demultiplex

MAX104Decimation DIV4 ModeThe MAX104 also offers a special decimated, demulti-plexed output (Figure 8) that discards every other inputsample and outpu

In a typical single-ended configuration, the analoginput signal (Figure 10a) enters the T/H amplifier stageat the in-phase input (VIN+), while the inv

MAX104Offset AdjustThe MAX104 provides a control input (VOSADJ) to com-pensate for system offsets. The offset adjust input is aself-biased voltage div
