Product details
Overview
X9269TV24IZ-2.7T1 from Intersil is a dual digitally controlled potentiometer (XDCP™) IC with 256-tap resolution per channel, 2-wire serial interface, nonvolatile data registers (DR0–DR3), and 100kΩ end-to-end resistance. It operates from 2.7V to 5.5V, supports power-on recall of wiper positions, and delivers <5µA standby current. Used in precision analog trimming for voltage regulators, sensor signal conditioning, and audio gain control.
For engineers reviewing the X9269TV24IZ-2.7T1 datasheet, X9269TV24IZ-2.7T1 pinout, X9269TV24IZ-2.7T1 application, or X9269TV24IZ-2.7T1 equivalent, this page provides verified functional specifications, validated TSSOP-24 pin mapping, confirmed 2-wire bus timing behavior, and real-world use cases in industrial trimming and programmable biasing circuits.
Technical Context
The X9269TV24IZ-2.7T1 integrates two independent 256-tap resistor arrays (50kΩ/100kΩ versions), each with a volatile 8-bit Wiper Counter Register (WCR) and four nonvolatile 8-bit Data Registers (DR0–DR3). Its 2-wire interface supports read/write/transfer operations including global register transfers and increment/decrement commands with SCL-synchronized wiper stepping.
Each potentiometer functions as a three-terminal device (RH/RL/RW) or two-terminal variable resistor. Wiper resistance is 300Ω typical at VCC = 3V and 150Ω at VCC = 5V. Power-on recall loads DR0 into the WCR, ensuring deterministic startup behavior without host intervention.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| End-to-End Resistance | 100kΩ - defines full-scale analog range for voltage division or gain setting |
| Resolution | 256 taps (0.4%) - enables fine-grained adjustment with ±1 MI absolute linearity error |
| Supply Voltage Range | 2.7V to 5.5V - supports single-supply operation across industrial and battery-powered systems |
| Standby Current | <5µA max - minimizes quiescent power in always-on or low-power monitoring circuits |
| Data Retention | 100 years - ensures long-term calibration stability without periodic refresh |
| Endurance | 100,000 write cycles per register - supports repeated field recalibration over product lifetime |
| Interface Protocol | 2-wire (I²C-compatible) - enables integration with standard microcontroller peripherals using minimal GPIO |
Pinout & Package
Package: 24-lead TSSOP (4.4mm body width), Pb-free plus anneal (RoHS compliant), MDP0044 package drawing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3–6, 19–22 | NC | No-connect pins - must remain unconnected; reserved for manufacturing test |
| 2, 11, 14, 24 | A0–A3 | Device address inputs - configure 4-bit slave address for multi-device 2-wire bus sharing |
| 7 | VCC | Positive supply rail - powers internal logic and resistor array; must be ≥ VH, VL, VW |
| 8, 15 | RL0, RL1 | Low terminals - fixed ends of potentiometer 0 and 1 resistor arrays |
| 9, 16 | RH0, RH1 | High terminals - fixed ends of potentiometer 0 and 1 resistor arrays |
| 10, 17 | RW0, RW1 | Wiper terminals - dynamically switched tap points controlled by WCR value |
| 12 | WP | Hardware write protect - LOW disables nonvolatile writes to DR registers |
| 13 | SDA | 2-wire bidirectional data - open-drain I/O requiring external pull-up; supports ACK polling |
| 23 | SCL | 2-wire clock input - synchronous timing reference for all serial transactions |
| 18 | VSS | System ground - return path for supply and analog signals; must be low-impedance |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent potentiometers | Enables simultaneous control of two analog paths (e.g., gain + offset) without inter-channel crosstalk |
| Four nonvolatile data registers per pot | Stores multiple calibrated settings (e.g., factory trim, user presets, temperature compensation points) |
| Power-on recall from DR0 | Guarantees known wiper position at startup without host initialization sequence |
| Increment/decrement command mode | Allows real-time fine-tuning via SCL pulses while SDA held HIGH/LOW - no full-byte transaction needed |
| 2.7V minimum supply operation | Supports direct interfacing with 3.3V and 2.8V microcontrollers without level-shifting |
Applications
| Audio Volume Control | Voltage Regulator Feedback Trimming |
|---|---|
Use Scenario: Programmable volume adjustment in portable audio amplifiers with digital control. IC Role / Device Role / Timing Role: Dual potentiometer acts as left/right channel attenuators; wiper positions set by MCU via 2-wire bus. Use Value: Replaces mechanical pots with stable, repeatable, and remotely configurable attenuation (±0.4% resolution). |

| Sensor Signal Conditioning | RF Bias Point Adjustment |
Use Scenario: Zero-point and gain scaling in bridge-based pressure or temperature sensor interfaces. IC Role / Device Role / Timing Role: Dual potentiometers configure differential amplifier gain and offset nulling network. Use Value: Achieves <±1 mV offset drift over temperature using nonvolatile DR storage and ratiometric tempco (20 ppm/°C). |
Use Scenario: Dynamic bias current tuning in GaAs FET RF power amplifiers for efficiency optimization. IC Role / Device Role / Timing Role: Potentiometer adjusts gate voltage divider; WP pin locks setting during RF transmission. Use Value: Maintains stable bias under thermal stress with 100-year data retention and 300Ω wiper resistance. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar digitally controlled potentiometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| X95820 | Single-channel, 256-tap, SPI interface, 50kΩ/100kΩ, same VCC range | Lacks dual-pot architecture and 2-wire compatibility; requires SPI peripheral instead of I²C | Select when system already uses SPI and only one pot is required; not suitable for dual-channel or I²C-bus designs |
| AD5242BRUZ100 | Dual 256-tap, I²C interface, 100kΩ, 2.7–5.5V, but no hardware WP pin or global transfer instructions | Missing write-protect pin and global XFR commands; lower endurance (50k cycles vs. 100k) | Choose for cost-sensitive designs where WP and multi-register atomic transfers are unnecessary |
Compared with X9269TV24IZ-2.7T1, X95820 reduces channel count and changes interface protocol, limiting reuse in dual-pot I²C systems; AD5242BRUZ100 retains dual-channel and I²C compatibility but sacrifices hardware write protection and register-level atomicity for simpler control.

FAQ
What is the operating voltage range for the X9269TV24IZ-2.7T1?
The X9269TV24IZ-2.7T1 operates from 2.7V to 5.5V, as confirmed in the Recommended Operating Conditions table. This range supports direct connection to 3.3V and 5V logic systems. The "-2.7" suffix explicitly denotes the extended low-voltage capability, distinguishing it from older 5V-only variants like X9269TS24.
Does the X9269TV24IZ-2.7T1 support true I²C communication?
Yes, the X9269TV24IZ-2.7T1 implements a fully compatible 2-wire interface with START/STOP conditions, ACK polling, and 7-bit slave addressing (using A0–A3). It responds to standard I²C clock frequencies up to 400kHz and uses open-drain SDA/SCL with external pull-ups, matching I²C electrical requirements.
How many nonvolatile registers does the X9269TV24IZ-2.7T1 have per potentiometer?
The X9269TV24IZ-2.7T1 has four 8-bit nonvolatile Data Registers (DR0–DR3) for each of its two potentiometers, totaling eight nonvolatile registers. These store wiper positions or system parameters and retain data for 100 years with 100,000 write cycles per register.
What is the function of the WP pin on the X9269TV24IZ-2.7T1?
The WP (Write Protect) pin on the X9269TV24IZ-2.7T1 disables nonvolatile writes to the Data Registers when pulled LOW. This prevents accidental overwriting of calibrated values during normal operation while allowing volatile wiper adjustments via the WCR. It remains inactive (no effect) when HIGH or floating.
Can the X9269TV24IZ-2.7T1 be used as a two-terminal variable resistor?
Yes, the X9269TV24IZ-2.7T1 can operate as a two-terminal variable resistor by connecting either RH or RL to the wiper (RW) terminal, effectively using only one end of the resistor array. This configuration is explicitly supported in the Functional Diagram and Circuit Level Applications section of the datasheet.
