Product details
Overview
X9259TS24-2.7 from Intersil (now Renesas) is a quad digitally controlled potentiometer (XDCP™) IC with 256-tap resolution, 2-wire serial interface, 50kΩ end-to-end resistance, 2.7V to 5.5V single-supply operation, and nonvolatile data register storage - used for precision gain, bias, and offset adjustment in analog signal chains.
For engineers reviewing the X9259TS24-2.7 datasheet, X9259TS24-2.7 pinout, X9259TS24-2.7 application, or X9259TS24-2.7 equivalent, this page delivers verified technical context, validated pin functions, real-world use cases in sensor conditioning and voltage regulation, and confirmed alternative parts with documented functional and application differences.
Technical Context
The X9259TS24-2.7 integrates four independent CMOS-switched resistor arrays, each with an 8-bit volatile Wiper Counter Register (WCR) and four 8-bit nonvolatile Data Registers (DR0–DR3). Wiper position is set via 2-wire bus commands including direct write, register transfer, and increment/decrement modes.
It operates as a 2-wire slave device with address pins A0–A3 enabling up to 16 devices on one bus. Hardware write protection (WP) disables nonvolatile writes when asserted low. Power-up loads DR#0 into each WCR, ensuring repeatable startup states without host intervention.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Number of DCPs | Four independent digitally controlled potentiometers on one die |
| Resolution | 256 taps (0.4% step resolution), enabling precise analog tuning |
| VCC Range | 2.7V to 5.5V - supports low-voltage microcontroller interfaces and battery-powered systems |
| End-to-End Resistance | 50kΩ ±20% - matches standard analog design expectations for gain/offset control |
| Wiper Resistance | 300Ω typical at VCC = 3V - minimizes loading error in high-impedance feedback paths |
| Standby Current | <5µA max - enables always-on calibration retention in power-sensitive applications |
| Data Retention | 100 years - ensures long-term configuration persistence without refresh |
Pinout & Package
Package: 24-lead SOIC (RoHS-compliant, M24.3 drawing), surface-mount, 0.300" wide body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A3 | 2-wire slave address inputs | Set LSBs of 8-bit I²C address; enable up to 16 devices on same bus |
| SDA | 2-wire bidirectional data line | Open-drain I/O requiring external pull-up; carries all instructions and data |
| SCL | 2-wire clock input | Master-provided timing signal; supports up to 400kHz operation |
| WP | Hardware write protect | Active-low pin disabling nonvolatile DR writes - prevents accidental configuration loss |
| RH0–RH3 / RL0–RL3 | Fixed terminals per DCP | Equivalent to mechanical pot ends; define total resistance path for each channel |
| RW0–RW3 | Wiper terminals per DCP | Output node position controlled by WCR; connects to amplifier feedback or reference nodes |
| VCC, VSS | Power supply rails | Single 2.7–5.5V supply; no separate analog/digital rails required |
| NC, DNC | No-connect / do-not-connect | Manufacturing test pins - must remain unconnected in PCB layout |
Key Features
| Feature | Design Value |
|---|---|
| Quad DCP integration | Replaces four discrete mechanical pots or DAC+resistor networks - reduces board area and BOM count |
| Nonvolatile DR storage | Retains four user-defined wiper positions per channel across power cycles - eliminates boot-time host reconfiguration |
| Increment/decrement mode | Enables real-time fine-tuning via SCL clock pulses - supports manual calibration without full register writes |
| 2.7V minimum VCC | Operates directly from Li-ion single-cell or 3.3V system rails - avoids level-shifting in mixed-voltage designs |
| Wiper resistance <300Ω | Minimizes gain error in op-amp feedback configurations using DCP as variable resistor |
Applications
| Audio Volume Control | Voltage Regulator Feedback Tuning |
|---|---|
Use Scenario: Adjusting gain in headphone amplifier stages or line-level audio paths. IC Role / Device Role / Timing Role: Acts as digitally programmable two-terminal variable resistor in op-amp feedback loop. Use Value: Enables software-controlled volume without mechanical wear, pop/click suppression via monotonic wiper stepping, and factory-trimmed default levels stored in DR0. |
Use Scenario: Setting output voltage of adjustable DC-DC converters or LDOs via feedback divider ratio. IC Role / Device Role / Timing Role: Replaces fixed resistors in R1/R2 feedback network; RH/RL define divider endpoints, RW sets tap point. Use Value: Allows dynamic output voltage scaling during system operation and retains last-set value after reboot - critical for adaptive power management. |
| Sensor Signal Conditioning | Offset/Trim Calibration |
Use Scenario: Scaling and zero-point adjustment in bridge-based pressure or temperature sensor front-ends. IC Role / Device Role / Timing Role: Configures gain and DC bias in instrumentation amplifier stages using dual DCPs per channel. Use Value: Supports multi-point calibration storage (DR0–DR3) for temperature compensation curves and eliminates manual trim pot rework during production. |
Use Scenario: Nulling input offset voltage in precision op-amp circuits or ADC reference buffers. IC Role / Device Role / Timing Role: Functions as three-terminal potentiometer between VREF, ground, and op-amp input to inject correction voltage. Use Value: Achieves sub-mV offset correction with 0.4% resolution and holds calibration indefinitely - essential for medical and test equipment accuracy. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar digitally controlled potentiometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD5242BRUZ10 | 2-channel, 10kΩ, I²C interface, 128-tap resolution, no hardware WP pin | Lacks quad-channel density and nonvolatile DR retention - requires host to reload settings at power-up | Choose when lower channel count, smaller package (16-TSSOP), or tighter end-to-end tolerance (±20% vs. ±20%) is prioritized over configuration persistence |
| MCP42010-I/P | 2-channel, 10kΩ, SPI interface, 256-tap, volatile-only wiper registers, no DR storage | Requires continuous host supervision; no power-up default recall - unsuitable for unattended recalibration | Prefer for SPI-based systems needing faster update rates (up to 10MHz) and where external EEPROM handles configuration backup |
Compared with AD5242BRUZ10 and MCP42010-I/P, the X9259TS24-2.7 uniquely delivers quad-channel density, 100-year nonvolatile storage of four wiper states per channel, and hardware write protection - making it optimal for self-contained, maintenance-free analog trimming in industrial and medical systems.

FAQ
What is the operating voltage range for the X9259TS24-2.7?
The X9259TS24-2.7 operates from 2.7V to 5.5V on a single supply. This extended low-voltage capability allows direct interfacing with 3.3V microcontrollers and battery-powered systems without level shifters. The -2.7 suffix explicitly denotes this 2.7V minimum rating, distinguishing it from the standard 5V±10% version.
How many independent potentiometers does the X9259TS24-2.7 contain?
The X9259TS24-2.7 integrates four completely independent digitally controlled potentiometers (DCPs) on a single monolithic CMOS die. Each DCP has its own RH, RL, and RW pins, plus dedicated volatile Wiper Counter Registers and four nonvolatile Data Registers - enabling fully autonomous control of four analog parameters.
Does the X9259TS24-2.7 retain wiper settings after power loss?
Yes - the X9259TS24-2.7 retains wiper positions in nonvolatile Data Registers (DR0–DR3) with 100-year data retention. At power-up, each DCP automatically loads its DR#0 value into the corresponding volatile Wiper Counter Register, ensuring repeatable startup behavior without host initialization.
What interface protocol does the X9259TS24-2.7 use?
The X9259TS24-2.7 uses a standard 2-wire (I²C-compatible) serial interface with open-drain SDA and input-only SCL. It supports up to 400kHz clock frequency, device addressing via A0–A3 pins, and nine distinct instructions including read/write WCR/DR, register transfers, and real-time increment/decrement mode.
Can the X9259TS24-2.7 be used as a two-terminal variable resistor?
Yes - each of the four DCPs in the X9259TS24-2.7 can be configured as either a three-terminal potentiometer (using RH, RL, and RW) or a two-terminal variable resistor (using RW and either RH or RL). This flexibility supports both voltage-divider and current-setting topologies in amplifier gain control and bias networks.
