X95840WV20IZ-2.7

Overview

The X95840WV20IZ-2.7 is a non-volatile digital potentiometer from the Renesas X9584 series, housed in a 20-pin TSSOP package. It integrates three independent channels, each offering 10 kΩ resistance with linear taper characteristics and 256 tap positions. The device utilizes a serial I2C interface for control and data transfer. It operates within a supply voltage range of 2.7 V to 5.5 V and maintains functionality across an industrial temperature range of -40°C to +85°C. The component features a low temperature coefficient of 4 ppm/°C and includes non-volatile memory to retain wiper settings upon power loss.

Feature Summary

• Three-channel architecture with 10 kΩ resistance per channel
• Non-volatile memory retains position settings without power
• Serial I2C interface for simplified system integration
• Low temperature coefficient of 4 ppm/°C for stability

Applications

• Audio volume and tone control circuits
• Programmable gain amplifier adjustments
• Voltage reference trimming
• LCD bias voltage adjustment

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix indicates the 2.7 V minimum operating voltage variant. Check current availability status as electronic components may experience supply fluctuations. Ensure the TSSOP-20 footprint matches the target PCB design constraints before procurement.

Selection Notes

Select this model when a multi-channel digital potentiometer with non-volatile storage is required. The 10 kΩ value suits moderate impedance applications. Verify that the I2C bus speed compatibility exists with the host microcontroller. Consider the 256-tap resolution for precise adjustment needs. Ensure the 2.7 V to 5.5 V supply range aligns with the system power rails.

Part Context

This part belongs to the X9584 family of non-volatile digital potentiometers. The series offers various channel counts and resistance values. The X95840 specifically denotes the three-channel configuration. The WV20 suffix typically indicates the TSSOP-20 package type. The 2.7 designation specifies the lower voltage limit of the operating range.

Replacement Considerations

Cross-reference with other X9584 series variants for different channel counts or resistance values. Verify pin-to-pin compatibility if substituting with similar I2C digital potentiometers from other manufacturers. Ensure the replacement supports non-volatile memory retention if power-down state preservation is critical.
