Product details
Overview
ISL90461TIE627Z-TK from Intersil is a volatile digitally controlled potentiometer (XDCP™) configured as a 100kΩ variable resistor with 32-tap resolution, ±35 ppm/°C tempco, and 2-pin UP/DN interface. It operates from 2.7V to 5.5V, draws ≤25µA active current, and targets precision bias and gain adjustment in analog signal paths.
For engineers reviewing the ISL90461TIE627Z-TK datasheet, ISL90461TIE627Z-TK pinout, ISL90461TIE627Z-TK application, or ISL90461TIE627Z-TK equivalent, key selection criteria include end-to-end resistance tolerance, wiper settling time (1µs), volatile memory behavior, SC-70 package footprint, and compatibility with low-power industrial sensor interfaces.
Technical Context
The ISL90461TIE627Z-TK implements a 31-element resistor array with electronic wiper switching controlled by a volatile up/down counter. Wiper position is set via CS-select and U/D edge-triggered increments, with no nonvolatile storage-settings reset on power cycle.
It functions exclusively as a 2-terminal variable resistor (RH–RL), not a 3-terminal potentiometer: RH serves as both wiper and high-side terminal, eliminating independent wiper output. Terminal voltage range is limited to VDD–GND, and absolute linearity is ±1 MI (minimum increment = RTOT/31).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RTOTAL | 100kΩ ±20% - defines full-scale resistance range for bias/gain tuning accuracy |
| Resolution | 32 taps - provides 31 discrete resistance steps between min and max values |
| Tempco | ±35 ppm/°C typical - ensures stable resistance over -40°C to +85°C industrial range |
| VDD Range | 2.7V to 5.5V - supports single-supply operation across 3.3V and 5V systems |
| Active Current | 25µA max - enables battery-sensitive applications without compromising update rate |
| Settling Time | 1µs - guarantees fast response after wiper movement for dynamic calibration loops |
| Wiper Resistance | 600Ω - contributes directly to total path resistance and affects low-end linearity |
Pinout & Package
ISL90461TIE627Z-TK is housed in a Pb-free 6-lead SC-70 package (JEDEC MO-203AB, Intersil P6.049), measuring 2.15mm × 1.35mm × 1.10mm (D × E1 × A), with gull-wing leads and 0.65mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Supply input | Power rail connection; must be decoupled locally due to CMOS switching noise sensitivity |
| GND | Ground reference | Return path for supply and signal; shared with RL terminal in 2-terminal configuration |
| U/D | Direction control | Edge-triggered input determining wiper increment/decrement on CS assertion |
| CS | Device select | Active-low enable; latches current wiper value on rising edge and enters standby (0.3µA) |
| RL | Low terminal | Fixed end of resistor array; forms 2-terminal variable resistance with RH |
| RH | High/wiper terminal | Wiper output tied to high end; no independent wiper node-only RH–RL resistance varies |
Key Features
| Feature | Design Value |
|---|---|
| Volatile 32-tap XDCP architecture | Enables rapid, repeatable calibration cycles without EEPROM wear-out or write latency |
| 2-pin UP/DN serial interface | Reduces PCB routing complexity versus I²C/SPI; requires only two GPIOs and no address logic |
| 100kΩ end-to-end resistance | Optimized for high-impedance bias networks in op-amp feedback, laser diode drivers, and sensor bridges |
| SC-70 package with 0.65mm pitch | Supports dense analog layouts while maintaining hand-solderability and thermal performance |
| ±35 ppm/°C tempco | Minimizes drift-induced error in temperature-varying environments such as automotive cabin sensors |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digitally controlled potentiometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD5171BRMZ-100 | I²C interface, nonvolatile EEPROM, 100kΩ, 64-tap resolution, 2.7–5.5V | Supports power-loss retention; higher resolution but slower interface and larger SOT-23-6 footprint | Choose when persistent settings across power cycles are required and I²C bus is available. |
| MCP4017T-103I/OT | UP/DN interface, volatile, 10kΩ nominal, SOT-23-6, 100kΩ not offered | Same 2-pin control simplicity but lower RTOTAL; requires external scaling for 100kΩ-equivalent ranges | Choose for cost-sensitive designs needing identical interface simplicity but accepting 10kΩ base value. |
Compared with AD5171BRMZ-100 and MCP4017T-103I/OT, the ISL90461TIE627Z-TK uniquely delivers 100kΩ resistance in SC-70 with 1µs settling and ±35 ppm/°C tempco-ideal for space-constrained, temperature-stable analog trimming where volatility is acceptable.

FAQ
What is the resistance tolerance of the ISL90461TIE627Z-TK?
The ISL90461TIE627Z-TK has an end-to-end resistance (RTOTAL) of 100kΩ with a tolerance of ±20%, as specified in the potentiometer specifications table of the FN8229 datasheet. This tolerance applies across the full operating temperature range (-40°C to +85°C) and defines the initial accuracy of the device before wiper positioning. The ISL90461TIE627Z-TK does not include factory calibration for tighter tolerance.
Does the ISL90461TIE627Z-TK retain wiper position after power loss?
No, the ISL90461TIE627Z-TK uses volatile memory only: wiper position resets to a default state (not guaranteed to be mid-scale) upon power removal or VDD dropout. Settings must be reinitialized by the host controller at startup. This behavior is inherent to the ISL90461TIE627Z-TK architecture and distinguishes it from nonvolatile alternatives like the AD5171.
Can the ISL90461TIE627Z-TK be used as a 3-terminal potentiometer?
No-the ISL90461TIE627Z-TK is internally configured as a 2-terminal variable resistor. RH is hardwired to the wiper and high end of the resistor array; there is no independent wiper output. Only RH–RL resistance varies. Using it as a traditional 3-terminal pot would require external circuitry and is not supported by the ISL90461TIE627Z-TK pinout or internal topology.
What is the maximum allowable voltage across RH and RL terminals of the ISL90461TIE627Z-TK?
The ISL90461TIE627Z-TK specifies RH and RL terminal voltages relative to GND: 0V to VDD. Therefore, the maximum voltage across RH–RL is limited to VDD (≤5.5V). Exceeding VDD or applying reverse polarity violates the absolute maximum rating and may damage the ISL90461TIE627Z-TK. No separate differential voltage rating is defined.
Is the ISL90461TIE627Z-TK compatible with lead-free reflow processes?
Yes-the "Z" suffix in ISL90461TIE627Z-TK denotes Pb-free plus anneal construction per RoHS, with 100% matte tin plating compatible with both SnPb and Pb-free soldering. Its SC-70 package is rated for peak reflow temperatures meeting or exceeding IPC/JEDEC J-STD-020 requirements for Pb-free processes.
