Product details
Overview
ISL90461WIE627Z-TK from Intersil is a volatile digitally controlled potentiometer (XDCP™) configured as a 10kΩ variable resistor with 32-tap resolution, ±35 ppm/°C tempco, and 2-pin Up/Down interface. It operates from 2.7V to 5.5V and delivers <25µA active current, serving in LCD contrast control and sensor bias adjustment circuits.
For engineers reviewing the ISL90461WIE627Z-TK datasheet, ISL90461WIE627Z-TK pinout, ISL90461WIE627Z-TK application, or ISL90461WIE627Z-TK equivalent, key selection criteria include RTOTAL tolerance (±20%), wiper resistance (600Ω), settling time (1µs), and SC-70 package compatibility with space-constrained analog trimming designs.
Technical Context
The ISL90461WIE627Z-TK implements a 31-element resistor array with electronic wiper switching controlled by CS and U/D inputs, enabling nonvolatile-free, cycle-limited digital trimming. Its CMOS architecture supports 1MHz up/down toggle rate and achieves ±1 MI absolute linearity over -40°C to +85°C.
Wiper position is latched on CS high transition, placing the device in 0.3µA standby mode. RH is internally tied to the wiper; RL serves as the low terminal-forming a two-terminal variable resistor without internal voltage divider configuration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RTOTAL | 10kΩ ±20% - defines full-scale resistance range for analog gain/offset tuning |
| Resolution | 32 taps - provides 3.23% step resolution per increment for fine parameter control |
| Tempco | ±35 ppm/°C typical - ensures stable resistance drift across industrial temperature range |
| Wiper Resistance | 600Ω max - limits signal path error in low-voltage sensor bias applications |
| Settling Time | 1µs - enables rapid reconfiguration during dynamic calibration sequences |
| Supply Current | 0.3µA standby - supports always-on trimming in battery-powered instrumentation |
| Interface | 2-pin UP/DN with CS - eliminates I²C/SPI overhead for minimal GPIO usage |
Pinout & Package
ISL90461WIE627Z-TK uses a Pb-free 6-lead SC-70 package (JEDEC MO203AB, pkg drawing P6.049), measuring 2.15mm × 1.35mm × 1.10mm with 0.65mm lead pitch. This ultra-compact outline suits high-density PCB layouts in portable electronics.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Positive supply input | Accepts 2.7V–5.5V; powers internal logic and resistor array |
| GND | Ground reference | Common return for supply, logic, and potentiometer terminals |
| U/D | Direction control | LOW = decrement wiper; HIGH = increment wiper on rising edge |
| CS | Chip select | LOW = enable counter; HIGH = latch position and enter standby |
| RL | Potentiometer low terminal | Fixed end of resistor array; forms two-terminal variable resistance with RH |
| RH | Wiper / high terminal | Internally connected wiper output; not a separate voltage tap |
Key Features
| Feature | Design Value |
|---|---|
| Volatile 32-tap XDCP | Enables fast, low-overhead digital trimming without EEPROM wear-out limitations |
| 2-pin UP/DN interface | Reduces MCU GPIO count vs. serial protocols-ideal for resource-constrained microcontrollers |
| 600Ω wiper resistance | Minimizes insertion error in precision current-sense or laser diode bias paths |
| 1µs output settling | Supports real-time recalibration in closed-loop sensor systems |
| 0.3µA standby current | Extends battery life in always-connected IoT sensor nodes requiring periodic trim updates |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digitally controlled potentiometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD5160BRJZ10-RL7 | 32-tap, 10kΩ, SPI interface, 5ppm/°C tempco, 125Ω wiper resistance | Requires dedicated SPI lines; lower tempco but higher cost and larger SOT-23-8 footprint | Preferred when higher precision and nonvolatile storage are required despite added interface complexity |
| MCP4017T-103E/CH | 64-tap, 10kΩ, I²C interface, ±100 ppm/°C tempco, 120Ω wiper resistance | Needs I²C bus and pull-up resistors; wider tempco reduces thermal stability in unregulated environments | Chosen when system already uses I²C and higher resolution outweighs tempco trade-off |
Compared with AD5160BRJZ10-RL7 and MCP4017T-103E/CH, the ISL90461WIE627Z-TK offers lowest GPIO overhead and best thermal stability for space-constrained analog trimming-though it lacks nonvolatile storage and requires external state retention.

FAQ
What is the total end-to-end resistance tolerance for ISL90461WIE627Z-TK?
The ISL90461WIE627Z-TK has a nominal RTOTAL of 10kΩ with a tolerance of ±20%, meaning the actual measured resistance between RH and RL pins falls within 8kΩ to 12kΩ across all wiper positions and operating conditions.
Does ISL90461WIE627Z-TK retain wiper position after power loss?
No, the ISL90461WIE627Z-TK is a volatile digital potentiometer. Wiper position resets to default (minimum resistance) upon power cycling. System-level firmware must reinitialize the desired tap setting after each power-up sequence.
What is the maximum allowable voltage across RH and RL terminals of ISL90461WIE627Z-TK?
The ISL90461WIE627Z-TK specifies RH and RL terminal voltages from 0V to VDD. With VDD rated 2.7V–5.5V, the maximum differential voltage across RH–RL is limited to the supply rail-exceeding this risks exceeding absolute maximum ratings and damaging the internal switch matrix.
Can ISL90461WIE627Z-TK be used in a three-terminal potentiometer configuration?
No. The ISL90461WIE627Z-TK is internally wired as a two-terminal variable resistor: RH is permanently connected to the wiper, and RL is the fixed low terminal. There is no independent wiper output pin-only RH and RL form the adjustable resistance path.
What is the minimum pulse width required on the U/D pin for reliable tap increment/decrement in ISL90461WIE627Z-TK?
The ISL90461WIE627Z-TK requires a minimum U/D LOW period (tIL) and HIGH period (tIH) of 300ns each. Pulse widths below this threshold may result in missed or double-counted steps due to insufficient internal clock sampling window.
