X9314WP-3

Digital Potentiometers Overview

The X9314WP-3 is a single-channel digitally controlled potentiometer (XDCP) manufactured by Renesas Electronics Corporation. It features a logarithmic resistance taper with an end-to-end resistance of 10 kΩ and 32 tap positions. The device utilizes a nonvolatile memory architecture to retain wiper settings during power loss, recalling the position upon power-up. It operates on a supply voltage range of 3 V to 5.5 V and employs a three-wire serial interface (U/D, INC, CS) for control. The component is housed in an 8-pin PDIP package.

Digital Potentiometers Feature Summary

• Nonvolatile storage of wiper position with recall on power-up
• Logarithmic taper with 32 tap positions and 10 kΩ total resistance
• Three-wire serial interface (Up/Down, Increment, Chip Select)
• Operates within a 3 V to 5.5 V supply voltage range

Digital Potentiometers Applications

• Digitally controlled resistance trimming
• Parameter adjustments in audio and signal processing circuits
• System calibration requiring persistent setting retention

Digital Potentiometers Part Context

The X9314WP-3 belongs to the X9314 series of solid-state potentiometers. This family provides CMOS EEPOT solutions designed as replacements for mechanical potentiometers in applications requiring digital adjustment. The 'WP' suffix indicates the specific plastic DIP packaging variant within this product line.

Digital Potentiometers Replacement Considerations

Direct replacement options include the X9314WSZ-3, which offers identical electrical specifications but utilizes SOIC packaging instead of PDIP. Designers must verify pin compatibility and thermal requirements when substituting between package types.
