X9315USZT1

Digital Potentiometers Overview

The X9315USZT1 is a digitally controlled potentiometer (XDCP) manufactured by Renesas Electronics Corporation. It features a single potentiometer circuit with a resistance value of 50 kOhms and 32 taps. The device utilizes a nonvolatile memory architecture to retain wiper position settings during power-off events. It operates via a serial 3-wire interface for control. The component is housed in an 8-SOIC surface-mount package. Electrical specifications include a supply voltage range of 2.7 V to 5.5 V and a typical temperature coefficient of ±300ppm/°C.

Digital Potentiometers Procurement Notes

Verify the specific suffix 'T1' against official Renesas documentation to confirm tape-and-reel packaging details. Confirm current lifecycle status as discontinued or limited availability through authorized channels. Ensure RoHS compliance matches project requirements by checking the specific manufacturing date code.

Digital Potentiometers Selection Notes

Select this component when a single-channel digital potentiometer with nonvolatile storage is required. The 50 kOhm resistance and 32-step resolution suit moderate precision applications. Verify that the 8-SOIC package dimensions fit the PCB layout constraints. Ensure the operating temperature range meets the environmental conditions of the target application.

Digital Potentiometers Part Context

This part belongs to the X9315 series of low-noise, low-power digitally controlled potentiometers. The series offers various resistance values and package options. The USZ designation indicates an SOIC-8 package variant. The T1 suffix typically denotes reel packaging for automated assembly processes.

Digital Potentiometers Replacement Considerations

Direct substitutes may include other X9315 variants with compatible pinouts and electrical characteristics. Verify equivalent nonvolatile memory functionality and interface compatibility before substitution.
