DESCRIPTION
The CAT5111 and CAT5113 are 100-tap digitally programmable
potentiometers (DPP) whose wiper positions are set by a simple 3-wire
digital up/down interface. 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.
