Product details
Overview
X9118TV14I-2.7 from Intersil is a single digitally controlled potentiometer (XDCP™) with 1024-tap resolution, 100kΩ end-to-end resistance, and 2-wire serial interface. It operates from 2.7V to 5.5V system supply (VCC), supports analog voltage rails from –5V to +5V (V+/V−), and delivers wiper resistance of 40Ω typical at 5V. It is used for precision gain control in audio amplifiers, DC bias trimming in RF power amplifiers, and programmable reference generation in sensor signal conditioning circuits.
For engineers reviewing the X9118TV14I-2.7 datasheet, X9118TV14I-2.7 pinout, X9118TV14I-2.7 application, or X9118TV14I-2.7 equivalent, this page provides verified technical context, validated pin functions, confirmed operating limits (–40°C to +85°C, 2.7V–5.5V VCC), nonvolatile register behavior, and real-world use cases including LCD contrast adjustment and LED transmitter power control.
Technical Context
The X9118TV14I-2.7 implements a 1023-element resistor array with CMOS transmission-gate switches controlled by a volatile 10-bit Wiper Counter Register (WCR). Its 2-wire interface uses open-drain SDA with pull-up (2–2.5kΩ typical) and active-high SCL, supporting up to 400kHz clock frequency and ACK polling during nonvolatile writes.
Four nonvolatile 10-bit Data Registers (DR0–DR3) store wiper positions or system parameters; DR0 loads automatically into WCR at power-up. Analog operation requires V+ ≥ RH/RL ≥ V−, with VCC, V+, and V− settling within 1ms of each other during power sequencing.
Key Specifications

Pinout & Package
Package: 14-lead TSSOP (Pb-free, RoHS compliant, pkg drawing M14.173).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Analog supply voltage | Bias rail for wiper switches; must be ≥ RH/RL voltage to prevent reverse-bias damage |
| V− | Analog supply voltage | Substrate and switch bias rail; must be ≤ RH/RL voltage; sets lower analog operating limit |
| VCC | Digital supply voltage | Powers 2-wire interface logic and control circuitry; 2.7V–5.5V range enables wide-system compatibility |
| VSS | System ground | Reference for digital logic; must be common with host MCU ground for reliable I²C communication |
| SDA | 2-wire bidirectional data | Open-drain I²C data line requiring external pull-up; handles address, opcode, and 10-bit register transfers |
| SCL | 2-wire clock input | Master-generated clock up to 400kHz; timing-critical for ACK polling and nonvolatile write completion detection |
| A0, A1 | Device address inputs | Set LSBs of 7-bit slave address (0101xxx); allow up to four X9118 devices on same bus |
| WP | Hardware write protect | Low-active pin preventing accidental nonvolatile writes to DR0–DR3 registers during normal operation |
| RH, RL | Potentiometer terminals | Fixed ends of 100kΩ resistor array; form voltage divider or two-terminal variable resistor with RW |
| RW | Wiper terminal | Switched tap point controlled by WCR; output impedance ≤100Ω ensures minimal loading in feedback paths |
| NC (pins 2, 10) | No connect | Manufacturing/test pins; must remain unconnected per datasheet to avoid functional interference |
Key Features
| Feature | Design Value |
|---|---|
| Power-on wiper recall | Automatically loads DR0 contents into WCR at startup - eliminates boot-time calibration overhead in embedded systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digitally controlled potentiometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD5171BRMZ-100 | 64-tap (6-bit) resolution, 100kΩ, I²C interface, 2.7V–5.5V VCC, but only one nonvolatile register (EEPROM) | Lacks multi-register storage for multi-point calibration; lower resolution limits fine-tuning granularity | Select when cost sensitivity outweighs resolution and register count requirements |
| MCP45HV51-103 | 257-tap (8-bit) resolution, 100kΩ, I²C interface, 2.7V–5.5V VCC, 5.5V analog tolerance (V+ to V−), no bipolar support | Cannot operate with negative analog voltages; lacks hardware WP pin and power-on DR0 recall | Choose for unipolar high-voltage (≤5.5V) applications where bipolar operation is unnecessary |

FAQ
What is the guaranteed operating temperature range for X9118TV14I-2.7?
The X9118TV14I-2.7 is rated for industrial operation from –40°C to +85°C. This range is confirmed in the Ordering Information table and applies to all electrical specifications unless otherwise noted. The device uses Intersil's qualified 14-lead TSSOP package with Pb-free (RoHS-compliant) termination and meets IPC/JEDEC J-STD-020 reflow standards.
Does X9118TV14I-2.7 support true bipolar analog operation?
Yes, X9118TV14I-2.7 supports true bipolar analog operation with V+ rated from –5.5V to +5.5V and V− rated from –5.5V to –2.7V, enabling RH/RL/RW operation across –5V to +5V. This allows use in AC-coupled circuits, dual-supply op-amps, and negative-bias RF applications - a key differentiator versus unipolar DCPs.
How does the power-on wiper recall function work in X9118TV14I-2.7?
At power-up, X9118TV14I-2.7 automatically loads the contents of Data Register 0 (DR0) into the volatile Wiper Counter Register (WCR), setting the initial wiper position. This occurs after VCC, V+, and V− stabilize within 1ms of each other. DR0 must be pre-programmed during manufacturing or field calibration to ensure deterministic startup behavior.
Can X9118TV14I-2.7 be used with standard I²C masters without protocol modification?
Yes, X9118TV14I-2.7 implements a standard 2-wire (I²C-compatible) interface with 7-bit slave address (0101xxx), START/STOP conditions, ACK polling, and 400kHz maximum clock rate. It requires only standard open-drain SDA/SCL signaling with appropriate pull-ups (2–2.5kΩ typical) and adheres to I²C timing specifications per FN8161 Rev 5.00.
What is the maximum wiper current rating for X9118TV14I-2.7?
The absolute maximum wiper current for X9118TV14I-2.7 is ±3mA, as specified in the Recommended Operating Conditions table. Exceeding this limit risks irreversible damage to internal CMOS switches. For continuous operation, design must ensure (VRH – VRL)/RTOTAL ≤ ±3mA - e.g., ≤±300mV across 100kΩ end-to-end resistance.
