Product details
Overview
X9015UM8Z-2.7 from Intersil is a volatile, digitally controlled potentiometer with 32-tap resolution, 50kΩ end-to-end resistance, and 2.7V–5.5V supply operation. It implements a three-wire up/down serial interface (CS/INC/U/D), delivers ≤50µA active current, and powers up at Tap #15-used for precision analog trimming in low-power sensor signal conditioning circuits.
For engineers reviewing the X9015UM8Z-2.7 datasheet, X9015UM8Z-2.7 pinout, X9015UM8Z-2.7 application, or X9015UM8Z-2.7 equivalent, key selection criteria include wiper resistance at 2.7V (400–1000Ω), ±1 MI absolute linearity, 1µA standby current, and MSOP-8 package compatibility with space-constrained industrial control modules.
Technical Context
The X9015UM8Z-2.7 uses a 5-bit up/down counter driving a resistor ladder of 31 series elements, with make-before-break electronic switches ensuring glitch-free wiper transitions. Its control logic responds to negative-edge-triggered INC pulses while U/D sets direction and CS enables selection or standby mode.
Wiper position is volatile and resets to Tap #15 on power-up; no nonvolatile storage is present. The device operates as a true 3-terminal potentiometer (RH/VH, RL/VL, RW/VW) or 2-terminal variable resistor, with ratiometric temperature coefficient of ±20 ppm/°C and total resistance TC of ±300 ppm/°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| End-to-End Resistance | 50kΩ ±20% - defines full-scale analog range and load interaction in voltage divider configurations |
| Supply Voltage Range | 2.7V–5.5V - enables direct interfacing with 3.3V and 5V logic without level-shifting |
| Active Supply Current | ≤50µA - supports battery-powered or energy-harvesting systems requiring ultra-low quiescent power |
| Standby Current | ≤1µA - allows deep-sleep retention of system state between trim adjustments |
| Absolute Linearity | ±1 MI (Minimum Increment = RTOTAL/31) - ensures ≤3.2% full-scale error across all taps for accurate calibration |
| Wiper Resistance | 400–1000Ω at VCC=2.7V - impacts output impedance and loading effects in high-gain amplifier feedback paths |
| Power-Up Wiper Position | Tap #15 - provides deterministic mid-scale default for fail-safe startup behavior |
Pinout & Package
Package: 8-lead MSOP (M8.118), 3.0mm × 3.0mm body, 0.65mm pitch, RoHS-compliant matte tin finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Positive supply input | Must be ≥ VH, VL, VW; powers internal logic and resistor array |
| CS | Chip select control | LOW enables device; HIGH with INC HIGH enters 1µA standby mode |
| INC | Increment clock input | Negative-edge triggered; advances or retracts wiper per U/D state |
| U/D | Direction control input | HIGH = increment tap; LOW = decrement tap; sampled synchronously with INC edge |
| RH/VH | High terminal | Fixed end of resistor string; connects to VCC or reference voltage rail |
| VSS | Ground reference | Return path for supply and signal; must be common with system ground |
| RL/VL | Low terminal | Fixed end opposite RH/VH; connects to VSS or signal return |
| RW/VW | Wiper output | Movable terminal; presents 400–1000Ω series resistance at 2.7V; outputs interpolated voltage |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar digitally controlled potentiometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| X9015US8Z-2.7 | Same electrical specs but in 8-lead SOIC (M8.15) package; 5.2mm × 4.0mm vs. MSOP's 3.0mm × 3.0mm | Preferred where board space permits and hand-soldering or legacy footprint reuse is required | Select when PCB layout accommodates larger SOIC and thermal mass aids reflow yield |
| AD5175BRMZ-50 | I²C interface, 256-tap resolution, nonvolatile memory, 10kΩ RTOTAL, 2.7–5.5V supply | Suitable for systems requiring power-loss retention or finer resolution; incompatible pinout and protocol | Choose when persistent wiper position or higher granularity outweighs added firmware complexity and cost |
Compared with X9015US8Z-2.7, the X9015UM8Z-2.7 saves >50% board area in dense industrial modules; versus AD5175BRMZ-50, it eliminates I²C stack dependencies and reduces BOM count-but requires host MCU to manage volatile state across power cycles.

FAQ
Is X9015UM8Z-2.7 pin-compatible with other X9015 variants like X9015US8Z-2.7?
No, X9015UM8Z-2.7 is not pin-compatible with X9015US8Z-2.7. Although both share identical pin functions (VCC, CS, INC, U/D, RH/VH, VSS, RL/VL, RW/VW), the X9015UM8Z-2.7 uses an 8-lead MSOP package (M8.118) with 0.65mm pitch and 3.0mm × 3.0mm body, whereas X9015US8Z-2.7 uses an 8-lead SOIC package (M8.15) with 1.27mm pitch and 5.2mm × 4.0mm body. PCB layout redesign is required for substitution.
Does X9015UM8Z-2.7 retain its wiper position after power cycling?
No, X9015UM8Z-2.7 does not retain wiper position after power cycling. It is a volatile digital potentiometer: upon power-up, the wiper always initializes to Tap #15 regardless of prior state. Host firmware must reprogram the desired tap position after each power-on reset to restore intended analog settings.
What is the maximum wiper current rating for X9015UM8Z-2.7 at 2.7V supply?
The maximum wiper current rating for X9015UM8Z-2.7 is ±3.75mA under all operating conditions, including at 2.7V supply. This limit applies regardless of tap position or voltage differential across RH/VH and RL/VL. Exceeding this current may cause irreversible resistance drift or wiper contact degradation.
Can X9015UM8Z-2.7 be used in a two-terminal variable resistor configuration?
Yes, X9015UM8Z-2.7 can be configured as a two-terminal variable resistor by connecting either RH/VH or RL/VL to RW/VW and using the remaining fixed terminal plus RW/VW as the two endpoints. In this mode, resistance varies from near-zero (at Tap #0 or #31) to 50kΩ (full scale), with wiper resistance contributing directly to total on-resistance.
What is the typical wiper resistance of X9015UM8Z-2.7 when operated at 2.7V?
The typical wiper resistance of X9015UM8Z-2.7 at 2.7V is 400–1000Ω, as specified in the datasheet's Potentiometer Specifications table. This value increases compared to operation at 5V (200–400Ω) due to reduced drive strength in the internal pass transistors, directly affecting output impedance in precision voltage divider applications.
