3 Description
The TPL0102-EP is a two-channel, linear-taper digital
potentiometer with 256 wiper positions. Each
potentiometer can be used as a three-terminal
potentiometer or as a two-terminal rheostat. The
TPL0102-EP-100 has an end-to-end resistance of
100 kΩ.
The TPL0102-EP has non-volatile memory
(EEPROM) which can be used to store the wiper
position. The internal registers of the TPL0102-EP
can be accessed using the I²C interface.
The TPL0102-EP is available in a 14-pin TSSOP
package with a specified temperature range of –40°C
to 125°C.
