Product details
Overview
X9315TSIZ-2.7 from Intersil is a digitally controlled potentiometer (XDCP™) implementing a 31-element resistor array with 32 wiper tap positions, nonvolatile wiper position storage, and 2.7V–5.5V supply operation. It functions as a three-terminal voltage divider or two-terminal variable resistor in analog signal conditioning, precision biasing, and programmable gain control circuits.
For engineers reviewing the X9315TSIZ-2.7 datasheet, X9315TSIZ-2.7 pinout, X9315TSIZ-2.7 application, or X9315TSIZ-2.7 equivalent, this device delivers low-noise (–120 dBV), temperature-compensated resistance (±300 ppm/°C), and high reliability (100,000 endurance cycles, 100-year data retention) in industrial-grade –40°C to +85°C operation.
Technical Context
The X9315TSIZ-2.7 uses a 5-bit up/down counter driving a decoder that selects one of 32 wiper positions across a monolithic resistor ladder. Wiper movement is controlled via CS, U/D, and edge-triggered INC inputs using a make-before-break switching architecture.
Its nonvolatile memory stores wiper position on CS↑ with INC HIGH, enabling automatic recall at power-up. The device operates in 2.7V–5.5V supply range with active current ≤80 µA (increment mode) and standby current ≤5 µA, supporting low-power embedded trimming applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| End-to-end resistance | 10 kΩ ±20% - defines full-scale analog adjustment range and load interaction in voltage divider configurations |
| Wiper resistance | 400–1000 Ω at VCC = 2.7V - impacts signal integrity and loading error when used as variable resistor |
| Supply voltage range | 2.7V to 5.5V - enables direct interface with 3.3V and 5V logic systems without level-shifting |
| Active supply current | 80 µA max - supports battery-powered or energy-constrained trimming applications |
| Nonvolatile store time | 5–10 ms - determines minimum system wait time before safe deassertion of CS after wiper update |
| Temperature coefficient | ±300 ppm/°C - ensures stable resistance ratio over industrial temperature range (–40°C to +85°C) |
| Resolution | 3% - corresponds to 1/31 step size (minimum increment), defining smallest controllable analog change |
Pinout & Package
Package: 8-lead SOIC (Pb-free, RoHS-compliant), JEDEC MS-012-AA, body dimensions 4.90 mm × 3.90 mm × 1.75 mm max.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Positive supply input | Power source for internal logic and resistor array; must be ≥ VH, VL, VW per absolute ratings |
| VSS | Ground reference | Return path for all internal currents; establishes 0V reference for RH/VH, RL/VL, and RW/VW terminals |
| RH/VH | High terminal | Fixed end of resistor array; voltage ranges from VSS to VCC depending on wiper position and configuration |
| RL/VL | Low terminal | Fixed end of resistor array; serves as reference point in voltage divider or current-limiting resistor applications |
| RW/VW | Wiper terminal | Movable contact output; connects to one of 32 taps; series resistance varies with VCC (400–1000 Ω @ 2.7V) |
| CS | Chip select | Active-low enable; initiates wiper movement when LOW; triggers nonvolatile store on rising edge with INC HIGH |
| U/D | Up/down direction control | Logic level sets wiper increment/decrement direction during INC transitions; may be changed dynamically while CS is LOW |
| INC | Increment clock input | Negative-edge triggered; advances wiper position in U/D-defined direction; timing requires tCYC ≥ 4 µs |
Key Features
| Feature | Design Value |
|---|---|
| Nonvolatile wiper storage | Retains last set position across power cycles; eliminates need for external EEPROM or initialization firmware |
| 3-wire serial interface | Requires only CS, U/D, and INC signals - minimal GPIO usage and no clock/data bus overhead |
| Industrial temperature range | Rated for –40°C to +85°C operation - suitable for automotive cabin electronics and industrial control modules |
| Low power consumption | 5 µA standby current enables always-on trimming in battery-backed systems without significant drain |
| Make-before-break switching | Prevents open-circuit transients during wiper movement - critical for stable biasing in amplifier feedback networks |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digitally controlled potentiometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD5175BRMZ-10 | 256-tap I²C interface; 10 kΩ; 2.7–5.5V; 500 ppm/°C tempco; 20 µA typical active current | Higher resolution but lacks native 3-wire SPI-like simplicity; requires I²C address management | Preferred when finer granularity (0.4% vs 3%) and I²C bus integration outweigh interface complexity |
| MCP41HV51-103 | 256-tap SPI interface; 10 kΩ; 4.5–18V supply; 100 ppm/°C tempco; 1 mA active current | Wider voltage range and lower tempco, but higher power and no nonvolatile store on power-down | Chosen for high-voltage analog front-ends where 100 ppm/°C stability justifies 20× higher active current |

FAQ
What is the operating temperature range for the X9315TSIZ-2.7?
The X9315TSIZ-2.7 is rated for industrial operation from –40°C to +85°C. This range is confirmed in the Ordering Information table (Page 2) and Recommended Operating Conditions (Page 6) of the FN8179 datasheet, where "TSIZ" suffix explicitly denotes the –40°C to +85°C grade in Pb-free SOIC packaging.
Does the X9315TSIZ-2.7 retain its wiper position after power loss?
Yes, the X9315TSIZ-2.7 stores the wiper position in nonvolatile memory and automatically recalls it on power-up. This behavior is guaranteed by the device's EEPROM-based store function, activated by a CS↑ transition while INC is HIGH, and is documented in the Principles of Operation (Page 4) and Endurance/Data Retention specs (Page 7).
What is the maximum wiper current rating for the X9315TSIZ-2.7?
The maximum wiper current (IW) for the X9315TSIZ-2.7 is ±3.75 mA, as specified in the Recommended Operating Conditions table (Page 6). Exceeding this limit risks exceeding the 10 mW maximum power rating and may degrade wiper resistance stability or long-term reliability.
Can the X9315TSIZ-2.7 be used with a 3.3V microcontroller interface?
Yes, the X9315TSIZ-2.7 supports 2.7V–5.5V supply and has VIH = 0.7 × VCC and VIL = 0.1 × VCC, making it fully compatible with standard 3.3V CMOS logic levels. Its 3-wire interface requires no level shifting when driven by 3.3V GPIOs, as verified in the DC Electrical Specifications (Page 7).
What package type does the X9315TSIZ-2.7 use?
The X9315TSIZ-2.7 uses an 8-lead narrow-body SOIC package (JEDEC MS-012-AA), Pb-free and RoHS-compliant, with package drawing M8.15. This is explicitly stated in the Ordering Information table (Page 2) under the "PACKAGE" column for all X9315TSIZ-2.7 variants.
