Product details
Overview
X9015US8IZ-2.7T1 from Intersil is a volatile, digitally controlled potentiometer with 32-tap resolution, 10kΩ 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 to Tap #15-used for precision analog trimming in low-power sensor signal conditioning circuits.
For engineers reviewing the X9015US8IZ-2.7T1 datasheet, X9015US8IZ-2.7T1 pinout, X9015US8IZ-2.7T1 application, or X9015US8IZ-2.7T1 equivalent, key selection criteria include its volatile wiper positioning, ±1 MI absolute linearity, 200–400Ω wiper resistance at 5V, -40°C to +85°C industrial temperature range, and SOIC-8 RoHS-compliant packaging.
Technical Context
The X9015US8IZ-2.7T1 integrates a 5-bit up/down counter, decoder logic, and a 31-resistor ladder array to position the RW/VW wiper terminal across discrete taps. Its "make-before-break" switching ensures continuity during tap transitions, while wiper movement is edge-triggered on INC and direction-controlled by U/D state.
Operation requires CS low to enable control; returning CS high while INC is high places the device in 1µA standby mode. The wiper position is not retained after power loss-resetting to Tap #15 at each power-up-and RTOTAL exhibits ±300 ppm/°C temperature coefficient with ratiometric stability of ±20 ppm/°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| End-to-End Resistance | 10kΩ ±20% - defines full-scale analog voltage division range and load interaction in bias networks. |
| Supply Voltage Range | 2.7V–5.5V - enables direct compatibility with 3.3V and 5V logic systems without level-shifting. |
| Active Supply Current | ≤50µA - supports battery-powered or energy-harvesting applications requiring ultra-low quiescent power. |
| Standby Current | ≤1µA - allows extended sleep-mode operation between trim adjustments without significant leakage drain. |
| Absolute Linearity Error | ±1 MI (Minimum Increment) - guarantees ≤±3.23% full-scale error across all 32 taps for accurate gain/offset calibration. |
| Wiper Resistance | 200–400Ω at VCC = 5V - limits loading effect on downstream op-amp inputs or reference nodes when used as variable feedback element. |
| Operating Temperature | -40°C to +85°C - qualifies for industrial-grade embedded control, motor drive feedback, and automotive cabin electronics. |
Pinout & Package
Package: 8-lead narrow-body SOIC (JEDEC MS-012-AA, POD M8.15), RoHS-compliant, matte tin termination, 5.20mm × 4.00mm body size, 1.27mm lead pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Positive supply input | Accepts 2.7V–5.5V; must be ≥ VH, VL, VW per absolute rating; powers internal logic and resistor array. |
| CS | Chip select control | Active-low enable: drives device into standby when high while INC is high; synchronizes wiper updates. |
| INC | Increment clock input | Negative-edge triggered; toggling moves wiper one tap up/down depending on U/D state. |
| U/D | Direction control input | High = increment (tap +1); Low = decrement (tap –1); sampled on each INC falling edge. |
| RH/VH | High-side fixed terminal | Connects to VCC or maximum analog rail; forms top node of voltage divider or current path. |
| VSS | Ground reference | Return path for supply and analog signals; must be common with system ground for noise immunity. |
| RL/VL | Low-side fixed terminal | Connects to VSS or minimum analog rail; completes resistive string; referenced as Tap #0. |
| RW/VW | Wiper output terminal | Provides analog output at selected tap; series resistance ≤400Ω affects driving capability and settling time. |
Key Features
| Feature | Design Value |
|---|---|
| 32-tap volatile digital potentiometer | Enables precise, repeatable analog trimming without nonvolatile memory wear-out or write latency. |
| Three-wire up/down serial interface | Eliminates need for SPI/I²C controllers; compatible with GPIO-driven microcontrollers using minimal pins. |
| Make-before-break wiper switching | Prevents open-circuit glitches during tap transitions-critical for stable biasing in amplifier feedback loops. |
| Industrial temperature range (-40°C to +85°C) | Ensures reliable operation in motor control enclosures, factory automation sensors, and outdoor instrumentation. |
| Low 1µA standby current | Permits integration into always-on subsystems where background calibration occurs infrequently. |

IC Role / Device Role / Timing Role: Serves as ratiometric divider between VCC and VSS; output at RW/VW feeds precision reference buffer. Use Value: ±20 ppm/°C ratiometric TC ensures stable reference over temperature; 10kΩ value minimizes loading on buffered sources. | Use Scenario: Setting constant-current threshold in linear LED drivers for architectural lighting control. IC Role / Device Role / Timing Role: Configures feedback resistor network in LM317-based current source or op-amp current mirror. Use Value: 200–400Ω wiper resistance introduces negligible error in high-side sensing; 2.7V min VCC supports single-cell Li-ion powered designs. |
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-10 | I²C interface, nonvolatile EEPROM storage, 10kΩ, 64-tap resolution, 2.7V–5.5V supply. | Retains wiper position after power cycle; suited for systems requiring persistent settings without host reinitialization. | Select when power-loss retention is mandatory and I²C infrastructure exists; avoid if GPIO-only control or ultra-low standby (<1µA) is required. |
| MCP4017T-103I/OT | Up/down interface like X9015, but nonvolatile, 10kΩ, 64-tap, SOT-23-6 package, 1.8V–5.5V supply. | Smaller footprint and lower voltage support; retains setting; higher resolution but no make-before-break switching. | Choose for space-constrained PCBs needing nonvolatility and 1.8V compatibility; not recommended where glitch-free transitions are critical. |
Compared with X9015US8IZ-2.7T1, AD5170BRMZ-10 offers EEPROM persistence and I²C flexibility but higher standby current and no make-before-break; MCP4017T-103I/OT provides smaller size and lower VCC support but lacks glitch-free switching and has different pinout-neither is pin-compatible.

FAQ
What is the power-up behavior of the X9015US8IZ-2.7T1?
The X9015US8IZ-2.7T1 initializes its wiper to Tap #15 (midpoint) upon every power-up event. Because it is a volatile device, no prior wiper position is retained-this deterministic reset simplifies system startup sequencing and eliminates dependency on stored state. The X9015US8IZ-2.7T1 achieves wiper stability within 5 µs after VCC reaches valid operating voltage, as specified in tPU timing parameter.
Does the X9015US8IZ-2.7T1 support true 3-wire serial communication?
Yes-the X9015US8IZ-2.7T1 uses a dedicated 3-wire up/down interface consisting of CS (chip select), INC (increment clock), and U/D (up/down direction) signals. It does not implement SPI or I²C protocols. Each falling edge on INC advances the wiper one tap in the direction indicated by the U/D pin state, enabling simple GPIO-based control without protocol overhead or address decoding.
What is the maximum allowable voltage across RH/VH and RL/VL terminals of the X9015US8IZ-2.7T1?
The X9015US8IZ-2.7T1 specifies ΔV = |VH – VL| ≤ 5V as an absolute maximum rating. This limit applies regardless of VCC level and must be respected to prevent damage to the internal resistor string or transfer gates. Exceeding this differential voltage-even with VCC within 2.7V–5.5V-may cause irreversible degradation of linearity or terminal integrity.
How does the "make-before-break" feature benefit circuit design with the X9015US8IZ-2.7T1?
The X9015US8IZ-2.7T1's make-before-break switching ensures that the wiper remains electrically connected to at least one tap during transitions-preventing momentary open-circuit conditions. This avoids voltage spikes or signal discontinuities in sensitive analog paths, such as op-amp feedback networks or reference dividers, where even nanosecond interruptions could trigger latch-up or comparator chatter.
Can the X9015US8IZ-2.7T1 be used in a two-terminal variable resistor configuration?
Yes-the X9015US8IZ-2.7T1 supports two-terminal operation by connecting either RH/VH or RL/VL to the same node as RW/VW, effectively using the wiper and one fixed terminal as a programmable resistor. In this mode, total resistance varies from near-zero (Tap #0 or #31) to RTOTAL (10kΩ), with wiper resistance contributing directly to minimum on-resistance-verified at 200–400Ω for VCC = 5V in the X9015US8IZ-2.7T1 datasheet.
