Product details
Overview
ISL90461WIH627Z-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, draws ≤25µA active current, and is used for precision bias and gain adjustment in sensor interfaces and laser diode drivers.
For engineers reviewing the ISL90461WIH627Z-TK datasheet, ISL90461WIH627Z-TK pinout, ISL90461WIH627Z-TK application, or ISL90461WIH627Z-TK equivalent, key selection criteria include end-to-end resistance tolerance, wiper settling time (1µs), volatile memory behavior, and SOT-23-6 Pb-free package compatibility with industrial temperature range (-40°C to +85°C).
Technical Context
The ISL90461WIH627Z-TK implements a 31-element resistor array with electronic wiper switching controlled by CS and U/D signals. Its volatile counter architecture stores wiper position only while powered, requiring reinitialization at power-up.
It uses CMOS logic with TTL-compatible inputs (VIH = 0.7×VCC, VIL = 0.3×VCC), supports up/down toggle rates up to 1MHz, and exhibits low parasitic capacitance (CH/CL/CW = 10/10/25pF) critical for stable analog signal paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RTOTAL | 10kΩ ±20% - defines full-scale resistance range for bias/gain scaling |
| Resolution | 32 taps - provides 31 discrete resistance steps between RH and RL |
| Tempco | ±35 ppm/°C typical - ensures <0.3% resistance drift over -40°C to +85°C |
| Supply Range | 2.7V to 5.5V - compatible with 3.3V and 5V logic/system rails |
| Active Current | ≤25µA at 3V - enables ultra-low-power operation in battery-sensitive designs |
| Settling Time | 1µs - guarantees fast wiper response for dynamic calibration loops |
| Wiper Resistance | 600Ω max - limits insertion error in precision voltage divider configurations |
Pinout & Package
ISL90461WIH627Z-TK is housed in a 6-lead SOT-23 package (JEDEC MO178AB, pkg drawing P6.064), RoHS-compliant with 100% matte tin termination and MSL3 rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Power supply input | Accepts 2.7V–5.5V; powers internal logic and resistor array |
| GND | Ground reference | Common return path for all analog and digital functions |
| U/D | Direction control input | High = increment wiper toward RH; Low = decrement toward RL |
| CS | Chip select input | Active-low enable; latches wiper position on rising edge |
| RL | Potentiometer low terminal | Fixed end of resistor array; forms 2-terminal variable resistance with RH |
| RH | Potentiometer high/wiper terminal | Wiper output tied internally to high end; resistance RH–RL varies with tap position |
Key Features
| Feature | Design Value |
|---|---|
| Volatile wiper control | Eliminates nonvolatile memory wear-out; requires external initialization on power-up |
| 2-pin serial interface | Reduces PCB routing complexity vs SPI/I²C; needs only CS and U/D signals |
| Low power standby | 0.3µA supply current when CS = VDD - ideal for always-on sensor conditioning |
| Industrial temperature range | -40°C to +85°C operation - validated for automotive cabin and industrial control environments |
| Pb-free SOT-23 package | RoHS-compliant with annealed matte tin finish - compatible with SnPb and Pb-free reflow |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digitally controlled potentiometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD5170BRJZ-10-R7 | Nonvolatile EEPROM storage; I²C interface; 10kΩ RTOTAL; same SOT-23-6 package | Retains wiper position after power cycle; requires I²C bus resources | Select when persistent settings are required and I²C is available |
| MCP4017T-103E/OT | Volatile operation; U/D interface; 10kΩ RTOTAL; SC-70-6 package (smaller footprint) | Same control protocol but different package dimensions and thermal characteristics | Select when board space is constrained and SC-70-6 is preferred |
Compared with AD5170BRJZ-10-R7 and MCP4017T-103E/OT, the ISL90461WIH627Z-TK offers identical 10kΩ resistance and U/D control but prioritizes low active current (25µA) and industrial-grade tempco in a Pb-free SOT-23-6 package optimized for cost-sensitive analog trimming.

FAQ
What is the resistance tolerance and temperature coefficient of the ISL90461WIH627Z-TK?
The ISL90461WIH627Z-TK has an end-to-end resistance (RTOTAL) of 10kΩ with ±20% tolerance and a typical temperature coefficient of ±35 ppm/°C. This ensures predictable resistance drift across the full industrial temperature range (-40°C to +85°C), making it suitable for precision analog trimming where stability matters more than absolute initial accuracy.
Does the ISL90461WIH627Z-TK retain its wiper position after power loss?
No, the ISL90461WIH627Z-TK uses volatile memory only. Wiper position is lost when VDD is removed and must be reinitialized by the host controller upon power-up. This design avoids EEPROM wear-out and simplifies firmware, but requires external logic to restore the desired tap setting at startup.
What are the voltage and timing requirements for the U/D and CS pins of the ISL90461WIH627Z-TK?
The U/D and CS inputs accept TTL-compatible logic levels: VIH ≥ 0.7×VDD and VIL ≤ 0.3×VDD. Timing requires tCU ≥ 25ns (U/D setup before CS low), tCI ≥ 50ns (CS setup before U/D change), and tSETTLE = 1µs for wiper output stabilization after each step - all verified at 1MHz toggle rate.
Can the ISL90461WIH627Z-TK be used in a 3-terminal potentiometer configuration?
No - the ISL90461WIH627Z-TK is internally wired as a 2-terminal variable resistor: RH is permanently connected to the wiper, and RL is the opposite fixed terminal. The device does not expose a separate wiper output; therefore, it cannot function as a traditional 3-terminal potentiometer with independent wiper access.
Is the ISL90461WIH627Z-TK RoHS compliant and what is its moisture sensitivity level?
Yes, the ISL90461WIH627Z-TK is RoHS compliant with Pb-free plus anneal construction (100% matte tin plating). It meets MSL Level 3 per J-STD-020, with a floor life of 168 hours at ≤30°C/60% RH, and is qualified for peak reflow temperatures up to 260°C.
