X9313UPZ

Digital Potentiometers Overview

The X9313UPZ is a single-channel digital potentiometer IC manufactured by Renesas Electronics Corporation. It features a resistance value of 50 kOhms with a linear taper and 32 tap positions. The device utilizes non-volatile memory to retain wiper settings and operates on a 5V supply voltage. It employs an Up/Down (U/D, INC, CS) serial interface for control. The component is housed in an 8-PDIP package and supports surface or through-hole mounting depending on the specific variant configuration, though this part number indicates PDIP. It functions within a commercial temperature range of 0°C to +70°C.
