3 Description

The TPL0401x-10 device is a single-channel, linear-

taper digital potentiometer with 128 wiper positions.

The TPL0401x-10 has the low terminal internal and

connected to GND. The position of the wiper can be

available in a 6-pin SC70 package with a specified

temperature range of –40°C to +125°C. The part has

a 10-kΩ end-to-end resistance and can operate with

a supply voltage range of 2.7 V to 5.5 V. This kind of

product is widely used in setting the voltage reference

for low power DDR3 memory.

The TPL0401x-10 has the low terminal internal and

connected to GND.
