X9110TV14I

Digital Potentiometers Overview

The X9110TV14I is a single digitally controlled potentiometer (XDCP) manufactured by Renesas Electronics. It features 1024 resistor taps providing 10-bit resolution and a 100 kΩ end-to-end resistance. The device operates on a system supply voltage (VCC) ranging from 2.7 V to 5.5 V, with analog supplies (V+/V-) supporting -5 V to +5 V. It utilizes an SPI serial interface for write, read, and transfer operations. Key electrical parameters include a typical wiper resistance of 40 Ω at 5 V and a maximum standby current of 5 μA. The component is housed in a 14-lead TSSOP package.

Digital Potentiometers Feature Summary

• 1024-tap nonvolatile memory with power-on recall capability
• SPI serial interface for digital control
• Dual supply operation: 2.7V–5.5V logic, ±5V analog
• 100,000 data change endurance per register

Digital Potentiometers Applications

• Adjusting gain in voltage amplifier circuits
• Setting programmable DC reference voltages for comparators
• Volume control in audio signal processing
• Trimming offset voltage errors in operational amplifiers

Digital Potentiometers Procurement Notes

Verify the specific suffix 'I' against official datasheets to confirm temperature range and material compliance. Confirm availability status as this series may be subject to discontinuation notices. Ensure the ordering part number matches the required voltage and package specifications before procurement.

Digital Potentiometers Selection Notes

Select this component when a single-channel digital potentiometer with high resolution (10-bit) and nonvolatile storage is required. Verify that the 100 kΩ resistance value aligns with circuit impedance requirements. Ensure the design supports dual-supply operation if negative analog voltages are involved.

Digital Potentiometers Part Context

The X9110 belongs to the XDCP™ family of single digitally controlled potentiometers. It serves as a low-power CMOS alternative to mechanical potentiometers, offering improved reliability and smaller form factors. The device integrates four nonvolatile data registers to store multiple wiper positions.

Digital Potentiometers Replacement Considerations

Check for direct pin-compatible replacements within the X9110 series or the X9111 family. Verify that substitute components maintain the same 1024-tap resolution and SPI interface compatibility.
