DESCRIPTION
The
CAT5251
is
four
Digitally
Programmable
Potentiometers (DPPs™) integrated with control logic
and 16 bytes of NVRAM memory. Each DPP consists
of a series of resistive elements connected between
two externally accessible end points. The tap points
between each resistive element are connected to the
wiper outputs with CMOS switches. A separate 8-bit
control register (WCR) independently controls the
wiper tap switches for each DPP. Associated with
each wiper control register are four 8-bit non-volatile
memory data registers (DR) used for storing up to four
wiper settings. Writing to the wiper control register or
any of the non-volatile data registers is via a SPI serial
bus. On power-up, the contents of the first data
register (DR0) for each of the four potentiometers is
automatically loaded into its respective wiper control
register.
The CAT5251 can be used as a potentiometer or as a
two terminal, variable resistor. It is intended for circuit
level or system level adjustments in a wide variety of
applications. It is available in the -40°C to 85°C
industrial operating temperature range and offered in
a 24-lead SOIC and TSSOP package.
