... CONFIG IN Figure 1. Functional Diagram Detailed Description Digital Interface The MAX5167 has three logic control inputs and five address lines. The address lines are inputs to a demul- tiplexer that selects one of the 32 outputs in a standard addressing scheme (Table 1). The analog input is con- ...

... This voltage change, called hold step, is minimized by limiting the amount of stray capacitance seen by the hold capacitor. The MAX5167 limits the hold step to 0.25mV (typ). An output capacitor to ground can be used to filter out this small hold-step error. The MAX5167 contains an output buffer for each multi- plexer channel (32 total), so the hold capacitor sees a high-impedance input that reduces the droop rate ...

... CONFIG grounded responds to the upper 32 addresses (100000 through 111111). Input Drive Requirements The input of the MAX5167 feeds the inputs of 32 high- impedance buffers. These buffers are what charge the sample/hold capacitor through the multiplexer switch resistance. The bias current of a selected buffer is 10µ ...
