Designed to be used as electronic replacements for mechanical pots and trimmers, these devices are ideal for systems requiring automated or self-calibration. Unlike mechanical pots, DPPs operate reliably in hazardous environments and eliminate mechanical "wear and tear." Resistor tap points are connected to the output through CMOS switches or in the case of the CAT5111, through a unity gain buffer amplifier. Selection of the output tap position is controlled by an up/down counter which does not wrap around. The value of the counter can be stored in nonvolatile memory at power down and automatically recalled when power is restored. Available in 8-lead plastic DIP, SOIC, TSSOP and MSOP packages, they can be mounted anywhere in the system, unlike mechanical pots that require physical access or bulky shafts and knobs. DPPs bring variability and programmability to a wide range of applications including control, parameter adjustments and signal processing.
