Product details
Overview
X9119TV14IZ-2.7T1 from Intersil is a 10-bit (1024-tap), low-power, digitally controlled potentiometer (XDCP™) with 2-wire serial interface, 100kΩ end-to-end resistance, ±20% tolerance, and operation from 2.7V to 5.5V. It functions as a volatile wiper-controlled resistor array with four nonvolatile data registers and power-on recall of DR0, used for precision gain control in voltage amplifiers and DC bias adjustment in sensor signal conditioning circuits.
For engineers reviewing the X9119TV14IZ-2.7T1 datasheet, X9119TV14IZ-2.7T1 pinout, X9119TV14IZ-2.7T1 application, or X9119TV14IZ-2.7T1 equivalent, key selection criteria include its 2.7–5.5V supply range, 14-lead TSSOP package, 40Ω typical wiper resistance at 5V, <3µA standby current, and support for I²C-compatible 2-wire bus addressing via A0–A2 pins.
Technical Context
The X9119TV14IZ-2.7T1 implements a monolithic CMOS resistor ladder of 1023 segments with CMOS-switched wiper taps, decoded directly from a 10-bit volatile Wiper Counter Register (WCR). Communication occurs over a standard 2-wire (I²C-compatible) interface supporting read/write/transfer operations to WCR and four 10-bit nonvolatile data registers (DR0–DR3).
Power-up automatically loads DR0 into WCR, enabling deterministic startup behavior. Hardware write protection is provided via the WP pin, and device addressing uses three user-configurable address inputs (A0–A2), allowing up to eight devices on a shared bus. The architecture supports both 3-terminal potentiometer and 2-terminal variable resistor configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 10-bit (1024 taps): enables precise 0.1% step resolution across full 100kΩ range |
| End-to-End Resistance | 100kΩ ±20%: defines total resistive span between RH and RL terminals |
| Supply Voltage Range | 2.7V to 5.5V: supports single-supply operation across industrial and mixed-signal systems |
| Standby Current | <3µA maximum: enables ultra-low-power operation in battery-backed or energy-sensitive designs |
| Wiper Resistance | 40Ω typical at VCC = 5V: limits insertion error and signal distortion in precision divider applications |
| Data Retention | 100 years: ensures long-term storage of calibration settings in DR0–DR3 without refresh |

| 6 | SDA | Bidirectional open-drain data line; requires external pull-up resistor |
| 7 | VSS | System ground reference; must be low-impedance connection to minimize noise coupling |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digitally controlled potentiometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD5170BRMZ-100 | 10-bit, 100kΩ, SPI interface, 2.7–5.5V, but only two nonvolatile registers and no hardware WP pin | Lacks dedicated write-protect pin and has fewer storage registers; less suitable for safety-critical trim storage | Select when SPI interface is preferred and DR0–DR3 redundancy is not required |
| MCP45HV51-103E/ST | 8-bit, 10kΩ, 2-wire interface, 4.5–22V operation, higher voltage rating but lower resolution and no power-on DR0 recall | Supports higher-voltage analog rails but lacks automatic startup restore; unsuitable for low-voltage precision trimming | Select for high-voltage industrial biasing where 10-bit resolution is not critical |
Compared with AD5170BRMZ-100 and MCP45HV51-103E/ST, the X9119TV14IZ-2.7T1 offers superior configuration persistence (four NV registers + power-on DR0 recall), tighter wiper resistance control (40Ω typ), and hardware write protection-making it optimal for calibration-critical, low-power embedded systems requiring deterministic startup behavior.

FAQ
What is the operating voltage range for the X9119TV14IZ-2.7T1?
The X9119TV14IZ-2.7T1 operates from 2.7V to 5.5V, as confirmed by the Ordering Information table and Absolute Maximum Ratings section of the FN8162 datasheet. This extended low-voltage capability distinguishes it from the standard 5V±10% X9119 variants and enables compatibility with modern 3.3V and mixed-voltage systems.
Does the X9119TV14IZ-2.7T1 support automatic restoration of wiper position after power-up?
Yes, the X9119TV14IZ-2.7T1 automatically loads the contents of Data Register 0 (DR0) into the volatile Wiper Counter Register (WCR) at power-up, ensuring repeatable startup behavior without host intervention. This power-on recall function is explicitly documented in the Functional Diagram, Principles of Operation, and Register Description sections of the datasheet.
How many nonvolatile data registers does the X9119TV14IZ-2.7T1 include?
The X9119TV14IZ-2.7T1 includes four independent 10-bit nonvolatile data registers (DR0 through DR3), each capable of storing a full wiper position value or general-purpose system parameter. These registers support individual read/write/transfer operations and provide 100-year data retention with 100,000 endurance cycles per bit.
What package type is used for the X9119TV14IZ-2.7T1?
The X9119TV14IZ-2.7T1 is housed in a 14-lead TSSOP package (4.4mm body width), designated as M14.173 in the Intersil packaging documentation. This RoHS-compliant, surface-mount package supports automated assembly and provides thermal and electrical performance suitable for industrial temperature operation (-40°C to +85°C).
Can the X9119TV14IZ-2.7T1 be used as a 2-terminal variable resistor?
Yes, the X9119TV14IZ-2.7T1 can be configured as a 2-terminal variable resistor by connecting either RH or RL to the wiper (RW) terminal, as illustrated in Figure 14 ("TWO-TERMINAL VARIABLE RESISTOR") of the datasheet. This mode is commonly used for current limiting, gain control, and bias adjustment where only one adjustable resistance node is required.
