Renesas X9116WM8Z-2.7T1

Overview

X9116WM8Z-2.7T1 from Intersil is a solid-state, nonvolatile digitally controlled potentiometer (XDCP™) designed for precision trimmer replacement in analog signal conditioning and power supply feedback loops. It features 16 wiper taps, 10kΩ end-to-end resistance, 2.7V to 5.5V supply operation, <1µA standby current, and 3-wire up/down serial interface - enabling stable, temperature-invariant resistance adjustment in embedded sensor calibration and DC-DC converter trimming.

For engineers reviewing the X9116WM8Z-2.7T1 datasheet, X9116WM8Z-2.7T1 pinout, X9116WM8Z-2.7T1 application, or X9116WM8Z-2.7T1 equivalent, this device delivers verified nonvolatile wiper position retention, low-power operation down to 2.7V, and MSOP-8 packaging suitable for space-constrained industrial control and instrumentation designs requiring mechanical trimmer elimination.

Technical Context

The X9116WM8Z-2.7T1 implements a 15-segment linear resistor array with CMOS-switched wiper selection, controlled by a 3-wire up/down serial interface (U/D, INC, CS). Its 4-bit counter drives a decoder that activates one of 16 tap positions, with make-before-break switching ensuring continuity during transitions.

Wiper position is stored in nonvolatile EEPROM upon CS rising edge while INC is high, and automatically recalled at power-up. The device operates across 0°C to +70°C, supports ±1mA wiper current, and maintains ±1 MI absolute linearity and ±0.2 MI relative linearity over its full range.

FAQ

What is the minimum supply voltage required for reliable operation of the X9116WM8Z-2.7T1?

The X9116WM8Z-2.7T1 is specified for operation from 2.7V to 5.5V. At 2.7V, it maintains full functionality including wiper movement, nonvolatile store, and 16-tap resolution. Wiper resistance increases to 400–1000Ω at this voltage, which must be accounted for in low-impedance feedback paths. The device meets all timing and electrical specifications across this range per the FN8160.2 datasheet.

Does the X9116WM8Z-2.7T1 retain its wiper position after power cycling?

Yes, the X9116WM8Z-2.7T1 stores the last wiper position in nonvolatile EEPROM memory. Upon power-up, the device automatically recalls and applies that stored position to the wiper terminal. This behavior is guaranteed across 100,000 store cycles and 100 years of data retention under recommended operating conditions.

Can the X9116WM8Z-2.7T1 be used in a two-terminal variable resistor configuration?

Yes, the X9116WM8Z-2.7T1 supports two-terminal operation by connecting either VH/RH or VL/RL to a fixed potential and using VW/RW with the other terminal. In this mode, resistance between VW/RW and the grounded terminal varies from near-zero (at endpoint) to R_TOTAL. The datasheet confirms this use case in "Basic Configurations" (page 7) and specifies ±1mA wiper current limits.

What is the absolute linearity specification for the X9116WM8Z-2.7T1, and how is it defined?

The X9116WM8Z-2.7T1 has ±1 MI (Minimum Increment) absolute linearity, where 1 MI = R_TOTAL/15 ≈ 667Ω for the 10kΩ version. This means the actual wiper voltage deviates no more than ±1 MI from the ideal linear step at any tap position. Verified per test condition in the datasheet (page 4, Note 1), this ensures predictable voltage division in precision trimming applications.

Is the X9116WM8Z-2.7T1 RoHS compliant, and what does the 'Z' suffix indicate?

Yes, the 'Z' suffix in X9116WM8Z-2.7T1 denotes Pb-free plus anneal construction per Intersil's specification: 100% matte tin plate termination, RoHS-compliant molding compounds and die attach, and MSL2 moisture sensitivity rating. This ensures compatibility with both SnPb and lead-free reflow processes without compromising reliability or solder joint integrity.
