... This initialization period takes 10µs. The MAX5422/MAX5423/MAX5424 are intended for cir- cuits requiring digitally controlled adjustable resis- tance, such as LCD contrast control (where voltage biasing adjusts the display contrast), or programmable filters with adjustable gain and/or cutoff frequency ...
