CAT5116RIMSOP

The CAT5116RIMSOP is one member of the CAT5116 series.The CAT5116 is a log-taper single digitally programmable potentiometer (DPP(TM)) designed as a electronic replacement for mechanical potentiometers and trim pots.Ideal for automated adjustments on high volume production lines, DPP ICs are well suited for applications where equipment requiring periodic adjustment is either difficult to access or located in a hazardous or remote environment.

Features of the CAT5116RIMSOP are:(1)100-position, log-taper potentiometer; (2)non-volatile EEPROM wiper storage; (3)10nA ultra-low standby current; (4)single-supply operation: 2.5V - 5.5V; (5)increment up/down serial interface; (6)CAT5116RIMSOP resistance value: 32k; (7)CAT5116RIMSOP available in 8-pin MSOP,TSSOP,SOIC and DIP packages.The CAT5116 contains a 100-tap series resistor array connected between two terminals RH and RL.An up/down counter and decoder that are controlled by three input pins, determines which tap is connected to the wiper, RW.With INC set low, the CAT5116 may be de-selected and powered down without storing the current wiper position in nonvolatile memory. This allows the system to always power up to a preset value stored in nonvolatile memory.

The absolute maximum ratings of the CAT5116RIMSOP can be summarized as:(1)supply voltage:-0.5 to 7V;(2)operating ambient temperature:-40 to +85;(3)storage temperature:150.Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to CAT5116RIMSOP. Absolute Maximum Ratings are limited values applied individually while other param- eters are within specified operating conditions, and functional operation at any of these conditions is NOT implied. CAT5116RIMSOP performance and reliability may be impaired by exposure to absolute rating conditions for extended periods of time.The CAT5116 operates like a digitally controlled potentiometer with RH and RL equivalent to the high and low terminals and RW equivalent to  the mechanical potentiometer's wiper. There are 100 tap positions including the resistor end  points, RH and RL. There are 99 resistor elements connected in series between the RH and RL terminals.
