X95840WV20IZ-2.7T1

Overview

The X95840WV20IZ-2.7T1 is a non-volatile digital potentiometer from the Renesas X9584 series, housed in a 20-pin TSSOP package. It integrates three independent potentiometers with a resistance value of 10 kΩ and linear taper characteristics. The device features 256 tap positions per channel and utilizes a serial I2C interface for communication. Operating within a supply voltage range of 2.7 V to 5.5 V, it maintains a temperature coefficient of 4 ppm/°C and functions reliably between -40°C and +85°C.

Feature Summary

• Three-channel configuration with 10 kΩ resistance and 256 tap positions
• Non-volatile memory retains wiper settings without power
• Serial I2C interface for control and data transfer
• Low temperature coefficient of 4 ppm/°C for stability

Applications

• Audio volume and tone control circuits
• Programmable gain amplifiers
• Voltage reference adjustment
• Sensor calibration systems

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for obsolescence notices, as specific suffixes may indicate end-of-life status. Ensure the I2C address configuration matches system requirements before integration.

Selection Notes

Select this component when multi-channel digital adjustment with non-volatile retention is required. Compare against the X9583 variant if only two channels are needed. Verify that the I2C bus speed and pull-up resistor values align with the controller specifications. Ensure the 10 kΩ resistance fits the target circuit impedance constraints.

Part Context

This part belongs to the X9584 family of solid-state potentiometers, which replaces mechanical pots in applications requiring durability and programmability. The 'WV' suffix typically denotes wide voltage operation, while 'IZ' indicates the TSSOP package and lead-free composition. The '2.7' suffix specifies the minimum operating voltage threshold.

Replacement Considerations

Direct pin-compatible replacements include other X9584 variants with matching channel counts and resistance values. Cross-reference with Intersil legacy part numbers if maintaining design continuity with older hardware. Verify that substitute components support the same I2C protocol and non-volatile memory architecture.
