Product details
Overview
X9110TV14IZ-2.7T1 from Intersil is a dual-supply, low-power, 1024-tap digitally controlled potentiometer (XDCP™) with SPI interface, 100kΩ end-to-end resistance, ±5V analog voltage range (V+/V−), and industrial temperature rating (−40°C to +85°C). It functions as a programmable three-terminal potentiometer or two-terminal variable resistor in precision analog signal conditioning circuits.
For engineers reviewing the X9110TV14IZ-2.7T1 datasheet, X9110TV14IZ-2.7T1 pinout, X9110TV14IZ-2.7T1 application, or X9110TV14IZ-2.7T1 equivalent, key selection criteria include its 2.7V–5.5V system supply compatibility, nonvolatile wiper position storage across four registers, power-on recall from DR0, <5µA standby current, and 14-lead TSSOP package with verified SPI timing compliance up to 2.5MHz.
Technical Context
The X9110TV14IZ-2.7T1 implements a monolithic CMOS 1023-element resistor array with CMOS switch-controlled wiper positioning via a volatile 10-bit Wiper Counter Register (WCR). Its dual analog supplies (V+ and V−) enable bidirectional voltage operation across the potentiometer terminals (RH, RL, RW), supporting rail-to-rail analog signal adjustment within −5V to +5V bounds.
Communication uses standard SPI protocol with CS, SCK, SI, SO, HOLD, and WP pins; supports four-byte read/write instructions for WCR and data registers (DR0–DR3), plus two-byte transfer commands. Nonvolatile writes require high-voltage internal cycle (tWR = 5–10ms), while wiper response after instruction is ≤10µs (tWRL).
Key Specifications

Pinout & Package
Package: 14-lead TSSOP (RoHS-compliant, M14.173 drawing), 5.0mm × 4.4mm footprint, 0.65mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (V+) | Analog positive supply | Bias voltage for wiper switches; sets upper bound for RH/RL terminal voltage (≤ V+) |
| 2 (SO) | SPI serial output | Three-state data output synchronized to falling SCK edge; supports bus sharing with SI |
| 3 (A0) | Device address input | Configures 8-bit slave address; enables multi-device SPI daisy-chaining or parallel addressing |
| 4 (SCK) | SPI clock input | Drives all serial data transfers; rising edge latches SI, falling edge clocks SO |
| 5 (WP) | Hardware write protect | LOW disables nonvolatile writes to DR0–DR3; prevents accidental calibration loss during operation |
| 6 (SI) | SPI serial input | Latches opcode, address, and data on rising SCK edge; supports tri-state shared bus with SO |
| 7 (VSS) | System ground reference | Common return path for digital logic and interface circuitry; must be tied to PCB ground plane |
| 8 (V−) | Analog negative supply | Bias voltage for substrate and switch control; sets lower bound for RH/RL terminal voltage (≥ V−) |
| 9 (CS) | Chip select input | Active-LOW enables device; HIGH places SO in high-impedance state and enters standby mode |
| 10 (HOLD) | Serial bus pause control | Pauses ongoing SPI transaction when pulled LOW (with SCK LOW); resumes on HIGH transition |
| 11 (RW) | Wiper terminal | Output node of resistor array; connects to amplifier feedback, bias networks, or sensor interfaces |
| 12 (RH) | Potentiometer high terminal | Fixed end of resistor string; used as reference point in voltage divider or current-limiting configurations |
| 13 (RL) | Potentiometer low terminal | Fixed end of resistor string; referenced to V− in bipolar applications or ground in unipolar setups |
| 14 (VCC) | System supply voltage | Power source for digital interface and control logic; must ramp within 1ms of V+ and V− at power-up |
Key Features
| Feature | Design Value |
|---|---|
| Four nonvolatile data registers (DR0–DR3) | Enables storage of up to four independent calibration points or operating modes without external EEPROM |
| Power-on recall from DR0 | Automatically restores last-saved wiper position at startup-critical for fail-safe analog subsystem initialization |
| Wiper resistance ≤100Ω at 5V | Minimizes signal distortion and loading error in high-impedance feedback paths (e.g., op-amp gain control) |
| SPI-compatible serial interface | Reduces MCU GPIO count vs. parallel interface; supports daisy-chain or multi-drop configurations |
| Dual analog supply (V+/V−) | Supports true bipolar operation (±5V) for AC-coupled or differential signal chains without external biasing |
| 100-year data retention | Eliminates need for periodic recalibration in deployed industrial or medical equipment with long service life |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digitally controlled potentiometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD5242BRUZ100 | 256-tap, I²C interface, single 2.7–5.5V supply, no dual analog rails (V+/V−) | Limited to unipolar analog signals; lacks bipolar support and power-on recall from nonvolatile register | Choose for cost-sensitive, I²C-based systems where ±5V operation and DR0 auto-load are not required |
| MCP41HV51-103E/ST | 1024-tap, SPI interface, 100kΩ, but only single 4.5–18V analog supply (no V−), higher wiper resistance (120Ω typ) | Cannot support true bipolar signal paths; requires external level-shifting for negative voltages | Prefer when high-voltage analog operation (>5.5V) is needed and bipolar range is unnecessary |
Compared with AD5242BRUZ100 and MCP41HV51-103E/ST, the X9110TV14IZ-2.7T1 uniquely delivers verified ±5V analog rail support, automatic DR0 power-on recall, and <5µA standby current-making it optimal for low-power, bipolar, factory-calibrated analog subsystems.

FAQ
What is the guaranteed operating temperature range for X9110TV14IZ-2.7T1?
The X9110TV14IZ-2.7T1 is rated for industrial operation from −40°C to +85°C. This is confirmed in the Ordering Information table (Page 2) and Recommended Operating Conditions (Page 10) of the FN8158 datasheet. The "I" suffix in the part marking explicitly denotes the industrial temperature grade, distinct from commercial-grade variants.
Does X9110TV14IZ-2.7T1 support true bipolar analog operation?
Yes, the X9110TV14IZ-2.7T1 supports true bipolar analog operation via dedicated V+ and V− pins, enabling RH and RL terminals to swing between −5V and +5V relative to VSS. This is specified in the Absolute Maximum Ratings (Page 10) and Analog Specifications (Page 10), where V+ = +2.7V to +5.5V and V− = −5.5V to −2.7V for the -2.7 variant.
How does power-on recall work in X9110TV14IZ-2.7T1?
At power-up, the X9110TV14IZ-2.7T1 automatically loads the contents of Data Register 0 (DR0) into the volatile Wiper Counter Register (WCR), restoring the last-saved wiper position. This behavior is documented in the Device Description (Page 1), Functional Diagram (Page 2), and Principles of Operation (Page 5) sections of the datasheet.
What is the maximum SPI clock frequency supported by X9110TV14IZ-2.7T1?
The X9110TV14IZ-2.7T1 supports SPI clock frequencies up to 2.5MHz, as specified in the AC Timing table (Page 12) under parameter fSCK. This timing is validated across the full industrial temperature range and 2.7V–5.5V VCC supply, ensuring robust communication with standard microcontroller SPI peripherals.
Can X9110TV14IZ-2.7T1 be used as a two-terminal variable resistor?
Yes, the X9110TV14IZ-2.7T1 can be configured as a two-terminal variable resistor by connecting either RH or RL to the wiper (RW) terminal, as shown in Figure 13 (Page 15) and described in the Applications section (Page 2). This configuration is commonly used for gain control, current limiting, and bias adjustment where only resistance variation-not voltage division-is required.
