INTERFACE The AD5270/AD5271 ensure less than 1% end-to-end resistor
tolerance error and offer 50-times programmable (50-TP) memory.
The guaranteed industry leading low resistor tolerance error
feature simplifies open-loop applications as well as precision
calibration and tolerance matching applications. 1 EXT_CAP GND Figure 1. Mechanical rheostat replacements
Op-amp: variable gain control
Instrumentation: gain, offset adjustment
Programmable voltage to current conversions
Programmable filters, delays, time constants
Programmable power supply
Sensor calibration The AD5270/AD5271 are single-channel, 1024-/256-position
digital rheostats that combine industry leading variable resistor
performance with nonvolatile memory (NVM) in a compact
package. W SDO VSS 1 A 10/8 50-TP
