Product details
Overview
X9015US8Z-2.7T1 from Intersil is a volatile, digitally controlled potentiometer (XDCP™) with 32-tap resolution, 10kΩ end-to-end resistance, and 2.7V–5.5V supply operation. It functions as a solid-state replacement for mechanical potentiometers in analog trimming circuits, featuring three-wire up/down serial interface, wiper position reset to Tap #15 at power-up, and low standby current of 1µA max.
For engineers reviewing the X9015US8Z-2.7T1 datasheet, X9015US8Z-2.7T1 pinout, X9015US8Z-2.7T1 application, or X9015US8Z-2.7T1 equivalent, key selection criteria include its volatile memory behavior, 200Ω typical wiper resistance at 5V, ±1 MI absolute linearity, 3% resolution, and compatibility with 8-lead SOIC layout constraints.
Technical Context
The X9015US8Z-2.7T1 implements a 5-bit up/down counter driving a 31-resistor ladder array with make-before-break electronic switches. Wiper movement is edge-triggered on INC with direction controlled by U/D logic level, and device selection is managed via active-low CS.
It operates in volatile mode only-no EEPROM storage-so wiper position is lost on power-down and reinitialized to Tap #15. The resistor array delivers ratiometric temperature coefficient of ±20 ppm/°C and total resistance TC of ±300 ppm/°C, supporting stable analog voltage division across 0°C to +70°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Total Resistance | 10kΩ ±20% - defines full-scale analog range for voltage divider or current-setting applications |
| Supply Voltage Range | 2.7V–5.5V - enables direct interface with 3.3V and 5V logic systems without level shifting |
| Wiper Resistance | 200Ω typ. at VCC=5V - limits loading error in high-impedance feedback paths |
| Active Current | 50µA max. - supports ultra-low-power battery-operated trim circuits |
| Standby Current | 1µA max. - allows extended sleep-mode operation between adjustments |
| Absolute Linearity | ±1 MI (Minimum Increment) - ensures ≤3.2% full-scale error across all taps |
| Resolution | 3% - corresponds to 1/31 step size of RTOTAL, enabling fine analog control granularity |
Pinout & Package
Package: 8-lead narrow-body SOIC (JEDEC MS-012-AA, pkg drawing M8.15), RoHS-compliant, matte tin finish.

| VSS | Ground reference | Common return for supply, signals, and wiper path |
| CS | Chip select | Active-low enable; HIGH places device in standby (1µA) |
| INC | Increment clock | Negative-edge triggered; advances or retreats wiper per U/D state |

| Three-wire serial interface | Requires only CS, INC, and U/D signals-no clock or data lines-simplifying MCU GPIO usage |
| Make-before-break switching | Prevents open-circuit glitches during wiper transitions, critical for stable feedback loops |
| Low 1µA standby current | Permits integration into always-on systems where power budget is constrained to µA levels |
| ±20 ppm/°C ratiometric TC | Maintains consistent voltage division ratio over temperature, reducing calibration drift |

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, 10kΩ, 64-tap, 2.7–5.5V | Retains wiper position through power cycles; requires I²C bus and pull-ups | Select when persistent settings are required and I²C infrastructure exists |
| MCP41010-I/P | SPI interface, volatile, 10kΩ, 257-tap, 2.7–5.5V, higher ICC (120µA active) | Higher resolution and SPI compatibility but consumes >2× active current | Select when finer 0.4% step resolution is needed and SPI is preferred over 3-wire |
Compared with AD5170BRMZ-10 and MCP41010-I/P, the X9015US8Z-2.7T1 offers lowest active and standby current, simplest 3-wire control, and fastest wiper update (1–5µs), making it optimal for low-power, cost-sensitive trimming where volatility is acceptable.

FAQ
What is the default wiper position of the X9015US8Z-2.7T1 at power-up?
The X9015US8Z-2.7T1 initializes its wiper to Tap #15 (midpoint) on every power-up cycle. This behavior is fixed and non-programmable because the device is volatile-no memory retention is provided. The wiper remains at Tap #15 until modified via the INC and U/D pins, and resets to this position each time VCC is applied.
Does the X9015US8Z-2.7T1 support nonvolatile wiper storage?
No, the X9015US8Z-2.7T1 does not support nonvolatile storage. It is a volatile digitally controlled potentiometer: wiper position is lost when power is removed and always returns to Tap #15 at next power-up. For nonvolatile alternatives, consider devices like the AD5170BRMZ-10, which uses EEPROM to retain settings across power cycles.
What is the maximum wiper current rating for the X9015US8Z-2.7T1?
The X9015US8Z-2.7T1 specifies a maximum wiper current (IW) of ±3.75mA under recommended operating conditions. Exceeding this limit risks irreversible damage to the internal transfer gates. This rating applies across the full 2.7V–5.5V supply range and must be respected in both sourcing and sinking configurations of the RW/VW terminal.
Can the X9015US8Z-2.7T1 be used with a 3.3V microcontroller GPIO interface?
Yes, the X9015US8Z-2.7T1 is fully compatible with 3.3V microcontrollers. Its input thresholds (VIH = 0.7×VCC, VIL = 0.1×VCC) and 2.7V–5.5V supply range ensure reliable logic-level recognition at 3.3V. No level-shifting circuitry is required, and the device draws only 50µA active current-well within typical GPIO drive capability.
What is the meaning of "make-before-break" operation in the X9015US8Z-2.7T1?
"Make-before-break" means that during wiper movement between taps, the new connection is established before the old one is disconnected. This prevents momentary open-circuit conditions at the RW/VW terminal, eliminating voltage glitches in sensitive analog feedback paths. In the X9015US8Z-2.7T1, this behavior is inherent to its internal transfer gate architecture and occurs within tIW (1–5µs).
