Product details
Overview
X9315WMIZ-2.7R5419 from Intersil is a digitally controlled potentiometer (XDCP™) implementing a 31-element resistor array with 32 wiper tap positions, nonvolatile wiper position storage, and 3-wire serial interface (CS/U/D/INC). It operates from 2.7V to 5.5V, offers 10kΩ end-to-end resistance, ±20% tolerance, and −40°C to +85°C industrial temperature range. It serves as a solid-state replacement for mechanical potentiometers in precision analog trimming circuits.
For engineers reviewing the X9315WMIZ-2.7R5419 datasheet, X9315WMIZ-2.7R5419 pinout, X9315WMIZ-2.7R5419 application, or X9315WMIZ-2.7R5419 equivalent, this page delivers verified specifications including wiper resistance (400–1000Ω at 2.7V), absolute linearity (±1 MI), ratiometric tempco (±20 ppm/°C), noise (−120 dBV), and EEPROM endurance (100,000 cycles).
Technical Context
The X9315WMIZ-2.7R5419 uses a 5-bit up/down counter driving a decoder that selects one of 32 wiper taps across a monolithic 31-resistor ladder. Wiper movement follows make-before-break switching, preventing open-circuit transients during position changes.
Nonvolatile memory stores wiper position on CS↑ with INC↑, enabling automatic recall at power-up. The device supports both three-terminal potentiometer and two-terminal variable resistor configurations, with terminal voltages constrained between VSS and VCC and wiper current limited to ±3.75mA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RTOTAL | 10kΩ ±20% - defines full-scale resistance range for voltage divider or current-limiting use |
| VCC Range | 2.7V to 5.5V - enables direct compatibility with 3.3V and 5V systems without level-shifting |
| Wiper Resistance | 400–1000Ω at 2.7V - impacts minimum achievable output impedance and signal loading in bufferless designs |
| Resolution | 3% - corresponds to ~320mV step size in a 10V span, suitable for coarse analog tuning |
| Absolute Linearity | ±1 MI (Minimum Increment = RTOTAL/31 ≈ 322Ω) - limits worst-case voltage error vs ideal divider curve |
| Ratiometric Tempco | ±20 ppm/°C - ensures stable voltage division ratio over temperature, critical for sensor biasing |
| Active Current | 80µA max - enables low-power operation in battery-backed or energy-constrained systems |

| U/D | Up/Down direction | Logic level sets wiper increment/decrement direction during INC edge; changeable mid-sequence |
| INC | Increment clock | Negative-edge triggered; toggling moves wiper one position; HIGH during CS↑ initiates store |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digitally controlled potentiometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD5243BRMZ10 | I²C interface; dual-channel; 10kΩ; ±30% RTOTAL tolerance; 128 taps; no nonvolatile storage | Requires external EEPROM or MCU firmware to retain settings; better resolution but lower repeatability | Choose when I²C bus availability and dual-channel operation outweigh need for auto-recall |
| MCP41010-I/P | SPI interface; 10kΩ; ±20% RTOTAL; volatile wiper register only; no EEPROM; 257 taps | Needs continuous MCU refresh or external NVM; higher resolution but no power-loss retention | Choose for SPI-based systems where wiper position is dynamically updated and persistence is managed externally |
Compared with AD5243BRMZ10 and MCP41010-I/P, the X9315WMIZ-2.7R5419 uniquely combines 3-wire simplicity, guaranteed power-up recall, and industrial temperature rating-making it optimal for unattended or safety-critical trimming where firmware dependency must be minimized.

FAQ
What is the maximum wiper current rating for the X9315WMIZ-2.7R5419?
The X9315WMIZ-2.7R5419 has a maximum wiper current rating of ±3.75mA under recommended operating conditions. Exceeding this limit risks permanent damage to the internal wiper switch and resistor elements. This rating applies regardless of VCC voltage within the 2.7V–5.5V range and assumes proper voltage constraints (VH, VL, VW ≤ VCC).
Does the X9315WMIZ-2.7R5419 retain its wiper position after power cycling?
Yes, the X9315WMIZ-2.7R5419 retains its wiper position after power cycling. Its nonvolatile memory stores the last wiper setting whenever CS transitions HIGH while INC is HIGH. Upon power-up, the stored value is automatically recalled, placing the wiper at the previously saved tap position without MCU intervention.
Can the X9315WMIZ-2.7R5419 operate from a 3.3V supply?
Yes, the X9315WMIZ-2.7R5419 is fully specified for operation from 2.7V to 5.5V, making it compatible with standard 3.3V logic and power domains. At 3.3V, wiper resistance remains within 400–1000Ω, active current stays ≤80µA, and all timing parameters-including tIW (INC to VW change) and tCYC (INC cycle time)-remain valid per datasheet limits.
What is the absolute linearity specification for the X9315WMIZ-2.7R5419?
The X9315WMIZ-2.7R5419 has an absolute linearity specification of ±1 MI (Minimum Increment), where MI = RTOTAL/31 ≈ 322Ω for the 10kΩ version. This means the actual wiper voltage deviates from the ideal linear divider voltage by no more than ±322Ω worth of resistance error at any tap position, directly impacting voltage-setting accuracy in precision applications.
Is the X9315WMIZ-2.7R5419 RoHS compliant and lead-free?
Yes, the X9315WMIZ-2.7R5419 is RoHS compliant and lead-free. It uses Intersil's Pb-free material set with 100% matte tin plate (e3 termination finish), qualified for both SnPb and Pb-free soldering processes, and conforms to IPC/JEDEC J-STD-020 reflow profiles for moisture sensitivity level (MSL) 1.
