X9C303V8IC7843

Overview

The X9C303V8IC7843 is a digital potentiometer from the XDCP series, manufactured by Intersil (now Renesas). It features a single circuit with 100 tap positions and a total resistance of 32 kOhms. The device utilizes an Up/Down (U/D), Increment (INC), and Chip Select (CS) interface for control. It operates within a supply voltage range of 4.5V to 5.5V. The typical wiper resistance is 40 Ohms. The component is housed in an 8-TSSOP package.

Feature Summary

Provides precise digital adjustment of resistance via non-volatile memory storage
Supports linear taper characteristics for accurate signal attenuation
Enables remote programming through simple serial control interfaces

Applications

Audio volume control circuits
Gain adjustment in instrumentation amplifiers
Voltage reference trimming

Procurement Notes

Verify the specific suffix 'V8IC7843' against official Renesas legacy documentation to confirm exact tape-and-reel or tube packaging specifications. Ensure compatibility with existing PCB footprints for the 8-TSSOP package. Confirm that the 32k Ohm resistance value meets the target circuit requirements before finalizing procurement orders.

Selection Notes

Select this component when a compact, digitally adjustable resistor is required for calibration or gain setting. The 100-tap resolution offers a balance between precision and control complexity. Consider the 32k Ohm total resistance and 4.5V-5.5V operating range to ensure it fits within the system's power and impedance constraints.

Part Context

This part belongs to the X9C303 series of digital potentiometers, which are widely used in industrial and consumer electronics. Intersil was acquired by Renesas Electronics, and these components are now supported under the Renesas portfolio. The X9C303 series is known for its reliability and ease of integration into microcontroller-based systems.

Replacement Considerations

Consult Renesas Product Legacy Documents for officially confirmed substitute part numbers. Generic digital potentiometers may not match the specific 100-tap count or 32k Ohm resistance without verification.
