3 Description
The TPL0401x-10-Q1 device is a single-channel,
linear-taper digital potentiometer with 128 wiper
positions. The TPL0401x-10-Q1 has the low terminal
internal and connected to GND. The position of the
wiper can be adjusted using an I2C interface. The
TPL0401x-10-Q1 is available in a 6-pin SC70
package with a specified temperature range of â40°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-Q1 has the low terminal internal
and connected to GND.
