Product details
Overview
X9408WV24IZ-2.7T1 from Intersil (now Renesas) is a quad digitally controlled potentiometer (XDCP™) with 64-tap resolution per channel, 2.5kΩ end-to-end resistance, and 2-wire I²C-compatible interface. It operates from 2.7V to 5.5V supply, features nonvolatile data register storage (100-year retention), and delivers wiper response in ≤10µs for real-time analog tuning in precision instrumentation and sensor calibration circuits.
For engineers reviewing the X9408WV24IZ-2.7T1 datasheet, X9408WV24IZ-2.7T1 pinout, X9408WV24IZ-2.7T1 application, or X9408WV24IZ-2.7T1 equivalent, this device serves as a drop-in replacement for mechanical potentiometers in closed-loop biasing, gain control, and offset trimming where digital programmability, repeatability, and long-term stability are required.
Technical Context
The X9408WV24IZ-2.7T1 integrates four independent resistor arrays-each with 63 segments and 64 discrete tap points-controlled by volatile Wiper Counter Registers (WCR) and backed by four nonvolatile Data Registers per pot. Its 2-wire bus interface supports standard-mode I²C timing (400kHz max) with hardware write protection (WP pin) and addressable slave addressing via A0–A3 inputs.
Analog operation relies on dual-supply rails (V+ = +2.7V to +5.5V, V− = −2.7V to −5.5V), enabling true bipolar signal conditioning. Wiper resistance is 40Ω typical at 5V, and absolute linearity is ±1mI (±1% of full-scale), supporting high-fidelity voltage division in audio and measurement front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| End-to-end resistance | 2.5kΩ ±20% - sets gain/attenuation range and load matching in analog feedback paths |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digitally controlled potentiometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD5204BRUZ10 | Quad 10kΩ pot, SPI interface, no bipolar V+/V− support, 3.3V/5V only | Requires level-shifting for bipolar analog signals; lacks hardware WP pin | Choose when SPI-native host exists and unipolar operation suffices |
| MCP42050-I/SL | Dual 50kΩ pot, SPI interface, single-supply (2.7–5.5V), no nonvolatile wiper recall on power-up | Needs external initialization code; unsuitable for "set-and-forget" calibration | Prefer for cost-sensitive dual-pot designs where EEPROM persistence is optional |
Compared with AD5204BRUZ10 and MCP42050-I/SL, the X9408WV24IZ-2.7T1 uniquely combines quad 2.5kΩ channels, true bipolar analog operation (±2.7V), hardware write protection, and guaranteed power-up wiper recall from DR0-making it optimal for high-reliability, maintenance-free analog tuning in industrial and medical systems.

FAQ
What is the power-up behavior of the X9408WV24IZ-2.7T1?
On power-up, the X9408WV24IZ-2.7T1 automatically loads the contents of Data Register 0 (DR0) into each potentiometer's volatile Wiper Counter Register (WCR), restoring the last-saved wiper position. This occurs only after VCC, V+, and V− all reach stable levels-requiring proper power sequencing (V− first, then VCC/V+, then analog pins) and ≥1ms delay before issuing commands.
Does the X9408WV24IZ-2.7T1 support true bipolar analog operation?
Yes-the X9408WV24IZ-2.7T1 accepts independent analog supplies V+ = +2.7V to +5.5V and V− = −2.7V to −5.5V, enabling wiper voltages to swing fully between these rails. This allows direct interfacing with bipolar op-amps and sensors without level-shifting, unlike unipolar-only digital potentiometers.
How does the hardware write protect (WP) pin function on the X9408WV24IZ-2.7T1?
The WP pin on the X9408WV24IZ-2.7T1 is active-low: when held LOW, it blocks all nonvolatile writes to the four Data Registers per potentiometer. This prevents accidental overwrites during normal operation while allowing volatile WCR updates and reads-critical for protecting factory-calibrated settings in deployed equipment.
What is the maximum clock frequency supported by the X9408WV24IZ-2.7T1 I²C interface?
The X9408WV24IZ-2.7T1 supports standard-mode I²C operation up to 400kHz (tCYC ≥ 2500ns). Its timing parameters-including tSU:STA (600ns), tHD:DAT (30ns), and tAA (900ns)-are fully compliant with I²C specification v2.1, ensuring interoperability with common microcontrollers and FPGAs without custom timing adjustments.
Can the X9408WV24IZ-2.7T1 be used as a two-terminal variable resistor?
Yes-the X9408WV24IZ-2.7T1 can operate as a two-terminal variable resistor by connecting either VHx or VLx to VWx and using the remaining terminal with the unconnected end. This configuration maintains full 64-step resolution and leverages the same nonvolatile storage and low wiper resistance (40Ω typ.) as three-terminal use.
