Product details
Overview
X9015UM8-2.7 from Intersil is a volatile, digitally controlled potentiometer with 32-tap resolution, 50 kΩ end-to-end resistance, and 2.7 V to 5.5 V supply operation. It functions as a solid-state replacement for mechanical trimmers in analog voltage division and current-setting circuits, delivering ±1 MI absolute linearity and 1 µA standby current for low-power embedded biasing applications.
For engineers reviewing the X9015UM8-2.7 datasheet, X9015UM8-2.7 pinout, X9015UM8-2.7 application, or X9015UM8-2.7 equivalent, this device supports precise analog trimming in battery-powered instrumentation, sensor signal conditioning, and programmable gain stages where non-volatile storage is unnecessary and power efficiency is critical.
Technical Context
The X9015UM8-2.7 implements a 31-resistor string with a 5-bit up/down counter driving a decoder to select one of 32 wiper positions. Its three-wire serial interface (CS, INC, U/D) uses edge-triggered increment control and direction-select logic - no clock or data register required.
Wiper movement follows make-before-break switching, ensuring continuity during tap transitions, while power-up defaults to Tap #15. The device lacks EEPROM; wiper position is lost on power cycle and must be reinitialized by host firmware.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| End-to-End Resistance | 50 kΩ ±20% - sets full-scale analog range and load impedance in voltage divider configurations |
| Supply Voltage Range | 2.7 V to 5.5 V - enables direct interface with 3.3 V and 5 V microcontrollers without level shifting |
| Active Supply Current | 50 µA max - allows continuous real-time trimming in always-on sensor front-ends |
| Standby Current | 1 µA max - supports ultra-low-power sleep modes in portable devices |
| Absolute Linearity Error | ±1 MI (minimum increment = RTOTAL/31 ≈ 1.61 kΩ) - ensures ≤1.61 kΩ step error across full range |
| Wiper Resistance | 400–1000 Ω at 2.7 V - impacts output impedance and loading in high-gain amplifier feedback paths |
| Operating Temperature | 0°C to +70°C - validated for commercial-grade industrial control and test equipment environments |
Pinout & Package
Package: 8-lead MSOP (M8.118), 3.0 mm × 3.0 mm body, 0.65 mm 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 |
| VSS | Ground reference | Common return for supply, logic inputs, and pot terminals |
| RH/VH | High terminal | Fixed end of resistor string; voltage range = 0 V to VCC |
| RL/VL | Low terminal | Fixed end opposite RH/VH; defines bottom of voltage divider |
| RW/VW | Wiper output | Movable tap point; series resistance 400–1000 Ω at 2.7 V affects signal fidelity |
| U/D | Direction control input | Logic level determines wiper increment/decrement on next INC edge |
| INC | Increment trigger | Negative-edge sensitive; moves wiper one tap per valid transition |
| CS | Chip select | Active-low enable; HIGH places device in 1 µA standby mode |

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 8-lead SOIC (M8.15) package - 6.2 mm × 5.0 mm vs. MSOP's 3.0 mm × 3.0 mm | Preferred where board space permits larger footprint and hand-soldering or legacy layout reuse is needed | Select when thermal mass or PCB assembly compatibility outweighs size constraints |
| AD5175BRMZ-50 | I²C interface, 256-tap resolution, non-volatile EEPROM, 50 kΩ, 2.7–5.5 V - higher complexity and cost | Required where power-loss retention or fine-grained adjustment (0.2 kΩ steps) is mandatory | Choose only if volatile operation is unacceptable and I²C infrastructure exists |
Compared with X9015UM8-2.7, the SOIC variant offers identical performance in a larger, more manufacturable package, while the AD5175 adds EEPROM and I²C at the cost of increased firmware overhead and unit price - making X9015UM8-2.7 optimal for cost-sensitive, space-constrained, volatile-trimming applications.

FAQ
What is the default wiper position of the X9015UM8-2.7 at power-up?
The X9015UM8-2.7 initializes its wiper to Tap #15 (midpoint) on every power-up cycle. This behavior is hardwired and independent of prior state, as the device is volatile and retains no memory of previous settings. Firmware must reprogram the wiper position after each power application to restore desired analog values in the X9015UM8-2.7 circuit.
Does the X9015UM8-2.7 support I²C or SPI communication?
No, the X9015UM8-2.7 does not support I²C or SPI. It uses a dedicated three-wire up/down serial interface (CS, INC, U/D) with edge-triggered control - no clock, address, or data bytes required. This simplifies host interface design to basic GPIO toggling, distinguishing the X9015UM8-2.7 from protocol-based digital potentiometers.
Can the X9015UM8-2.7 be used in a two-terminal variable resistor configuration?
Yes, the X9015UM8-2.7 supports two-terminal operation by connecting either RH/VH or RL/VL to circuit ground or supply and using RW/VW with the remaining fixed terminal. In this mode, it functions as a digitally adjustable resistor with 50 kΩ total range and 400–1000 Ω wiper resistance at 2.7 V - verified in the X9015UM8-2.7 datasheet Figure 9 applications.
What is the maximum wiper current rating for the X9015UM8-2.7?
The X9015UM8-2.7 specifies a maximum wiper current (IW) of ±3.75 mA under all operating conditions. Exceeding this limit risks irreversible damage to internal transfer gates. This rating applies regardless of tap position or supply voltage, and must be enforced in both voltage-divider and variable-resistor configurations using the X9015UM8-2.7.
Is the X9015UM8-2.7 RoHS compliant and lead-free?
Yes, the X9015UM8-2.7 is RoHS compliant and features Pb-free plus anneal construction: 100% matte tin termination finish, lead-free molding compound, and die attach materials. It meets IPC/JEDEC J-STD-020 reflow requirements for both SnPb and Pb-free soldering processes - confirmed in the X9015UM8-2.7 ordering information table and packaging notes.
