GENERAL DESCRIPTION
The AD5231 is a nonvolatile memory1, digitally controlled
potentiometer2 with 1024-step resolution. The device performs
the same electronic adjustment function as a mechanical
potentiometer with enhanced resolution, solid state reliability,
and remote controllability. The AD5231 has versatile programming
that uses a standard 3-wire serial interface for 16 modes of
operation and adjustment, including scratchpad programming,
memory storing and restoring, increment/decrement, ±6 dB/step
log taper adjustment, wiper setting readback, and extra EEMEM
for user-defined information, such as memory data for other
components, look-up table, or system identification information.
In scratchpad programming mode, a specific setting can be
programmed directly to the RDAC register that sets the
resistance between Terminals W–A and Terminals W–B. This
setting can be stored into the EEMEM and is transferred
automatically to the RDAC register during system power-on.
The EEMEM content can be restored dynamically or through
external PR strobing, and a WP function protects EEMEM
contents. To simplify the programming, the linear-step increment
or decrement commands can be used to move the RDAC wiper
up or down, one step at a time. The ±6 dB step commands can
be used to double or half the RDAC wiper setting.
The AD5231 is available in a 16-lead TSSOP. The part is
guaranteed to operate over the extended industrial temperature
range of 40°C to +85°C.
