X95840UV20IZ-2.7T1

Overview

The X95840UV20IZ-2.7T1 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 2.7V to 5.5V and supports an operating temperature range of -40°C to +85°C. Key electrical parameters include a typical temperature coefficient of 4 ppm/°C and a contact resistance of 40 Ω.

Feature Summary

• Three-channel configuration with 10 kΩ resistance per channel
• Non-volatile memory retains wiper position upon power loss
• Serial I2C interface for simplified system integration
• Linear taper characteristic with 256 discrete tap settings

Applications

• Programmable gain amplifiers
• Voltage reference adjustment
• Digital volume control in audio systems

Procurement Notes

Verify the specific suffix 'UV' against official Renesas documentation to confirm pinout and voltage specifications, as distributor listings may vary. Confirm RoHS compliance status and check for end-of-life notices or last-time buy notifications prior to procurement planning.

Selection Notes

Select this component when a multi-channel, non-volatile digital potentiometer with I2C control is required. Ensure the 10 kΩ resistance value and 256-tap resolution meet the application's precision needs. Verify that the TSSOP-20 package fits the PCB layout constraints and that the I2C bus speed requirements are compatible with the device's maximum clock rate.

Part Context

This part belongs to the X9584 family of non-volatile digital potentiometers. The X9584 series typically includes variants with different channel counts (e.g., single, dual, triple) and resistance values. The 'X95840' designation specifically indicates the triple-channel variant within this product line.

Replacement Considerations

Check for direct cross-references such as the X9583 series if fewer channels are acceptable. Verify compatibility with alternative manufacturers like Microchip or Analog Devices offering similar I2C-controlled, non-volatile digital potentiometers with comparable pinouts and electrical characteristics.
