Datasheet	AD5255_AnalogDevices.pdf

The AD5255 provides dual 512-position and a single 128-position digitally controlled variable resistors1 (VR) in a TSSOP package.

This device performs the same electronic adjustment function as a potentiometer, trimmer, or variable resistor.

Each VR offers a pletely programmable value of resistance between the A terminal and the wiper or the B terminal and the wiper.

3 channels: Dual 512-position Single 128-position 25 kΩ or 250 kΩ full-scale resistance Low temperature coefficient: Potentiometer divider 15 ppm/°C Rheostat mode 35 ppm/°C Nonvolatile memory retains wiper settings Permanent memory write protection Linear increment/decrement ±6 dB increment/decrement I2C-compatible serial interface 2.7 V to 5.5 V single-supply operation ±2.25 V to ±2.75 V dual-supply operation Power-on reset time 256 bytes general-purpose user EEPROM 11 bytes RDAC user EEPROM GB.
