X9315TMIZ-2.7

Digital Potentiometers Overview

The X9315TMIZ-2.7 is a digitally controlled potentiometer (XDCP) manufactured by Renesas Electronics Corporation, formerly Intersil. It features a single potentiometer circuit with 32 tap positions and a resistance value of 100 kOhms. The device utilizes nonvolatile memory to retain wiper settings during power-off conditions. Control is managed via a 3-wire serial interface consisting of CS, U/D, and INC inputs. It operates within a supply voltage range of 2.7V to 5.5V and is housed in an 8-pin MSOP package.

Digital Potentiometers Feature Summary

• Nonvolatile memory retains wiper position upon power-up
• 3-wire serial control interface (CS, U/D, INC)
• 100 kOhm resistance with 32 linear tap positions
• Operates on 2.7V to 5.5V supply voltage

Digital Potentiometers Applications

• Audio volume control circuits
• Variable gain amplifier adjustment
• Programmable biasing networks
• Sensor calibration systems

Digital Potentiometers Procurement Notes

Verify the specific suffix for the X9315TMIZ-2.7 part number against official Renesas documentation to confirm tape-and-reel packaging versus tube packaging, as suffixes often dictate shipping format. Confirm RoHS compliance status and moisture sensitivity level (MSL) ratings prior to procurement to ensure compatibility with surface mount assembly processes.

Digital Potentiometers Selection Notes

Select this component when a 100 kOhm digital potentiometer with nonvolatile storage is required. Ensure the application supports the 3-wire incremental/decremental control logic. Verify that the operating temperature range meets system requirements, noting variations between industrial and commercial grades within the X9315 family.

Digital Potentiometers Part Context

The X9315 belongs to the XDCP™ family of low noise, low power digitally controlled potentiometers. This series integrates resistor arrays, wiper switches, and EEPROM into a compact package, serving as a direct replacement for mechanical potentiometers in space-constrained designs requiring programmable resistance.

Digital Potentiometers Replacement Considerations

Cross-reference with other X9315 variants such as X9315UMIZ or X9315WSIZ if different resistance values (50k or 10k) are acceptable. Verify pinout compatibility and interface signaling levels before substituting with generic digital potentiometer ICs.
