DESCRIPTION

The TPL0102 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 TPL0102-100 has an

end-to-end resistance of 100kΩ.

The TPL0102 has non-volatile memory (EEPROM) which can be used to store the wiper position. The internal

registers of the TPL0102 can be accessed using the I

C interface.

The TPL0102 is available in a 14-pin MicroQFN and 14-pin TSSOP package with a specified temperature range

of -40°C to +85°C.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas

Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of the Texas

Instruments standard warranty. Production processing does not

necessarily include testing of all parameters.

TPL0102 SLIS134B – MARCH 2011 – REVISED AUGUST 2011 www.ti.com Standard I2C Interface Details The bidirectional I2C bus consists of the serial clock (SCL) and serial data (SDA) lines. Both lines must be connected to a positive supply via a pullup resistor when connected to the output stages of a device. Data transfer may be initiated only when the bus is not busy.
