GENERAL DESCRIPTION
The AD5174 is a single-channel, 1024-position digital rheostat
that combines industry leading variable resistor performance
with nonvolatile memory (NVM) in a compact package.
This device supports both dual-supply operation at ±2.5 V to
±2.75 V and single-supply operation at 2.7 V to 5.5 V and offers
50-times programmable (50-TP) memory.
The AD5174 device wiper settings are controllable through the
SPI digital interface. Unlimited adjustments are allowed before
programming the resistance value into the 50-TP memory. The
AD5174 does not require any external voltage supply to facili-
tate fuse blow and there are 50 opportunities for permanent
programming. During 50-TP activation, a permanent blow fuse
command freezes the resistance position (analogous to placing
epoxy on a mechanical rheostat).
The AD5174 is available in a 3 mm × 3mm 10-lead LFCSP
package and in a 10-lead MSOP package. The part is guaranteed
to operate over the extended industrial temperature range of
40°C to +125°C.
