Product details
Overview
X9241AYVI from Intersil is a quad digital controlled potentiometer (XDCP™) IC with nonvolatile storage, 2-wire I²C interface, 64-tap resolution per channel, and -40°C to +85°C industrial temperature range. It integrates four independent 2kΩ resistor arrays in a single 20-lead TSSOP package and supports cascade configuration for extended resistance values up to 8kΩ. Used in precision analog trimming, sensor calibration, and programmable gain control circuits.
For engineers reviewing the X9241AYVI datasheet, X9241AYVI pinout, X9241AYVI application, or X9241AYVI equivalent, this page delivers verified specifications, validated pin functions, confirmed industrial-grade operating conditions, and two technically documented alternative parts for design continuity and sourcing flexibility.
Technical Context
The X9241AYVI implements four independent CMOS resistor arrays, each with 63 discrete segments and 64 wiper positions controlled by a volatile 6-bit Wiper Counter Register (WCR). Each array has four nonvolatile Data Registers (DR0–DR3) supporting up to four stored wiper settings per potentiometer.
It uses a standard 2-wire I²C-compatible interface with slave address determined by A0–A3 inputs, supports ACK polling during nonvolatile writes, and enables real-time wiper increment/decrement via clocked SCL pulses - all while maintaining ±300 ppm/°C end-to-end resistance temperature coefficient and <120 dBV noise.

Pinout & Package
20-lead thin shrink small outline package (TSSOP), RoHS-compliant, lead-free, industrial temperature grade (-40°C to +85°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SCL | Serial Clock input | Master-generated clock for I²C communication; timing-critical for ACK, read/write, and increment/decrement operations |
| SDA | Serial Data bidirectional I/O | Open-drain bus line requiring external pull-up; carries address, command, and data bytes |

| Low-power standby | 200–500 µA VCC current in standby (SCL/SDA = VCC, Addr = VSS) enables battery-operated applications |
Applications
| Audio Signal Level Control | Laser Diode Bias Calibration |
|---|---|
|
Use Scenario: Programmable volume/gain control in professional audio mixers with recallable presets. IC Role / Device Role / Timing Role: Four-channel analog attenuation element replacing mechanical pots; each pot sets gain for left/right channel and auxiliary paths. Use Value: DR0–DR3 store calibrated trim points for factory calibration and user presets; nonvolatile recall eliminates manual re-adjustment after power cycle. |
Use Scenario: Precision bias current setting for telecom laser diodes in optical transceivers. IC Role / Device Role / Timing Role: High-stability 2kΩ digital potentiometer acting as adjustable current-limiting resistor in laser driver feedback loop. Use Value: ±300 ppm/°C tempco and 100-year data retention ensure stable bias over product lifetime and thermal cycling. |
| Industrial Sensor Offset Trim | Programmable Power Supply Feedback |
|
Use Scenario: Factory-trimmed offset compensation for RTD or thermocouple signal conditioning circuits. IC Role / Device Role / Timing Role: Two-terminal variable resistor (VL–VW) used in op-amp summing junction to null DC offset voltage. Use Value: 64-tap resolution provides ≤31.25 Ω step size (2kΩ/64), enabling sub-mV offset correction at typical bridge excitation levels. |
Use Scenario: Adjustable voltage reference divider in isolated DC-DC converter feedback path. IC Role / Device Role / Timing Role: Three-terminal potentiometer (VH–VL–VW) setting output voltage via optocoupler-coupled error amplifier. Use Value: Cascade mode allows doubling resistance (to 4kΩ) while retaining single-wiper control, improving feedback divider SNR and stability margin. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar digital potentiometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD5242BRUZ10 | Single 10kΩ dual-channel pot; I²C interface; 256-tap resolution; no cascade mode; 100k write endurance | Higher resolution but lacks multi-pot integration and cascade capability; requires two devices for quad function | Select when higher tap count and lower tempco (±35 ppm/°C) outweigh need for integrated quad topology |
| MCP42010-I/P | Dual 10kΩ SPI-interface pot; 256-tap; volatile-only memory; DIP-14 package; no nonvolatile storage | No DR0 power-up recall; requires host firmware to restore settings; incompatible bus protocol | Choose for cost-sensitive, non-critical trimming where host can manage state and SPI is preferred over I²C |
Compared with X9241AYVI, AD5242BRUZ10 offers finer resolution and better temperature stability but requires external coordination for quad functionality, while MCP42010-I/P lacks nonvolatile storage and cascade support - making X9241AYVI uniquely suited for self-contained, field-updatable, multi-channel analog calibration.

FAQ
What is the exact resistor value and tolerance for X9241AYVI?
The X9241AYVI is configured with four 2kΩ resistor arrays, each with ±20% end-to-end resistance tolerance as specified in the Analog Specifications table. This value is fixed per the ordering information row confirming "Pot 0 = 2k, Pot 1 = 2k, Pot 2 = 2k, Pot 3 = 2k" for the Y-series variant. The X9241AYVI does not support selectable resistance values - only the 2kΩ configuration is valid for this part number.
Does X9241AYVI support power-up wiper recall, and how is it implemented?
Yes, X9241AYVI automatically loads the contents of Data Register 0 (DR0) into the volatile Wiper Counter Register (WCR) at power-up, ensuring repeatable wiper position without host intervention. This behavior is hardwired and occurs regardless of prior WCR state. The DR0 value must be written and stored nonvolatily (via Write Data Register or XFR WCR to Data Register) during initial calibration or configuration to guarantee correct recall on subsequent power cycles.
Can X9241AYVI operate with supply voltages other than 5V?
No - X9241AYVI is rated exclusively for 5V ±10% (4.5V to 5.5V) operation, as defined in both the Absolute Maximum Ratings and Recommended Operating Conditions sections. Applying voltages outside this range risks permanent damage or undefined behavior. The terminal voltage limits (+5V / -3.0V) apply independently to VH/RH, VL/RL, and VW/RW pins relative to VSS, but VCC must remain within the 4.5–5.5V window.
How does cascade mode work on X9241AYVI, and which pins must be connected?
Cascade mode on X9241AYVI links adjacent resistor arrays (e.g., POT0 to POT1) by connecting VL1/RL1 to VH0/RH0. The CM bit (bit 7 of WCR) enables cascading; when set to "1", the lower-order pot's wiper is disabled and its array extends the higher-order pot's resistance. Only one wiper remains active - all others must be disabled via their DW bits. External connections require VHx, VLx, and VWx wiring per Figure 9, with precise routing to avoid signal integrity issues.
What is the maximum wiper current rating for X9241AYVI, and how is it affected by temperature?
X9241AYVI supports ±4mA maximum wiper current for 2kΩ arrays at 25°C, with derating above 25°C per the DCP Wiper Current De-rating Curve. At 85°C, the maximum allowable wiper current drops to approximately ±2.5mA. Exceeding these limits risks irreversible degradation of the FET switches controlling wiper position. The absolute maximum rating assumes ≤10V differential (|VH – VL| ≤ 10V) and ≤50mW per potentiometer power dissipation.
