X9241AMVT1

Digital Potentiometers Overview

The X9241AMVT1 is a quad CMOS digital potentiometer IC from the X9241A series, manufactured by Renesas Electronics. It integrates four independent potentiometers with non-volatile memory to retain wiper settings upon power loss. The device features a serial two-wire interface for control and operates on a single 5V supply. Each potentiometer offers 64 tap positions with linear taper characteristics. The component is housed in a 20-pin TSSOP package and is rated for an industrial operating temperature range of -40°C to +85°C.

Digital Potentiometers Feature Summary

• Quad configuration with four independent 2kΩ, 10kΩ, 10kΩ, and 50kΩ potentiometers
• Non-volatile EEPROM storage retains wiper position after power cycle
• Serial 2-Wire (I2C-compatible) interface for data and address input
• 64-tap resolution with linear taper and ±20% resistance tolerance

Digital Potentiometers Applications

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

Digital Potentiometers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as historical batches may vary. Check for moisture sensitivity handling requirements during storage and reflow soldering processes. Ensure the specific suffix matches the required resistance values and package type.

Digital Potentiometers Selection Notes

Select this part when a quad digital potentiometer with mixed resistance values is required. The X9241AMVT1 provides distinct resistance steps for each channel (2k/10k/10k/50k). Verify that the 64-step resolution meets the application's precision needs. Ensure the I2C interface compatibility with the host microcontroller.

Digital Potentiometers Part Context

This component belongs to the X9241A family of digital potentiometers. It serves as a solid-state replacement for mechanical potentiometers in applications requiring programmable resistance. The 'M' suffix indicates the specific resistance combination of 2kΩ, 10kΩ, 10kΩ, and 50kΩ across the four channels.

Digital Potentiometers Replacement Considerations

Direct substitutes include X9241AMVZ and X9241AMVZT1. These alternatives offer identical electrical specifications and pinouts. Verify package compatibility and ensure the replacement part supports the required operating temperature range.
