The X9313WP-3 is a digitally controlled potentiometer (XDCP) manufactured by Intersil (now Renesas). It provides a single, digitally adjustable resistance value, allowing for precise control of circuit parameters without the need for manual trimming potentiometers.

Applications

• Volume control
• Brightness control
• Contrast control
• Bias adjustment
• Sensor calibration
• Replacing mechanical potentiometers

Features

• Single digital potentiometer
• 32 wiper positions
• End-to-end resistance: Typically 10 kOhms
• 3-wire serial interface (U/D, CS, INC)
• Non-volatile memory for storing wiper position
• Operating voltage: 2.7V to 5.5V
• Low power consumption
• Operating temperature range: -40°C to +85°C
• Pb-free/RoHS compliant

Benefits

• Precise and repeatable resistance adjustments
• Eliminates manual trimming
• Remote control capability
• Simplified calibration procedures
• Increased system reliability
• Space-saving design

Additional Details

The X9313WP-3 is controlled using a simple 3-wire serial interface, consisting of an Up/Down (U/D) input, a Chip Select (CS) input, and an Increment (INC) input. The wiper position can be incremented or decremented by applying pulses to the INC input while the CS input is low. The U/D input determines the direction of the adjustment. The non-volatile memory allows the wiper position to be stored and recalled even after power is removed. The 32 wiper positions provide a reasonable level of control for many applications. The 'WP' in the part number typically indicates the package type (e.g., PDIP or SOIC), and the '-3' often refers to a specific voltage rating or operating range. The datasheet should always be consulted for specific details.
