FEATURES  
DESCRIPTION  
Single Channel, 128-Position Resolution  
The TPL0401 is a single channel, linear-taper digital  
potentiometer with 128 wiper positions. The  
TPL0401A/B have the low terminal internal and  
connected to GND. The position of the wiper can be  
adjusted using an I2C interface. The TPL0401 is  
available in a 6-pin SC-70 package with a specified  
temperature range of –40°C to 125°C. The part has a  
10k end-to-end resistance and can operate with a  
supply voltage range of 2.7V to 5.5V. This kind of  
product is widely used in setting the voltage reference  
for low power DDR3 memory.  
10 kΩ End-to-End Resistance Options  
Low Temperature Coefficient: 35 ppm/°C  
I2C Serial Interface  
2.7 V to 5.5 V Single-Supply Operation
