Product details
Overview
ISL90462WIH627-TK from Intersil is a volatile digitally controlled potentiometer (XDCP™) configured as a 10kΩ variable resistor with 32-tap resolution, 2-pin Up/Down interface, and ±35ppm/°C tempco, used for precision analog biasing and gain control in sensor signal conditioning circuits.
For engineers reviewing the ISL90462WIH627-TK datasheet, ISL90462WIH627-TK pinout, ISL90462WIH627-TK application, or ISL90462WIH627-TK equivalent, key selection criteria include wiper settling time (1µs), active current (25µA max), supply voltage range (2.7V–5.5V), and SOT-23-6 package compatibility with space-constrained industrial sensor modules.
Technical Context
The ISL90462WIH627-TK implements a 31-element resistor array with electronic wiper switching controlled by CS and U/D inputs; wiper position is stored in volatile memory only upon CS high transition, requiring reinitialization at power-up.
It operates as a 2-terminal variable resistor or 3-terminal voltage divider depending on RH connection; wiper movement is monotonic with no wraparound, and absolute linearity error is limited to ±1 MI (minimum increment = RTOT/31).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RTOTAL | 10kΩ ±20% - defines full-scale resistance range for analog tuning accuracy and voltage divider ratio stability |
| Wiper taps | 32 discrete positions - enables 31-step resolution for fine-grained analog parameter adjustment |
| Tempco | ±35ppm/°C typical - ensures resistance drift remains under ±0.3% over -40°C to +85°C operating range |
| VDD range | 2.7V to 5.5V - supports direct integration with 3.3V and 5V microcontroller I/O without level shifting |
| Active current | 25µA max at 3V - minimizes quiescent power in battery-powered sensor front-ends |
| Settling time | 1µs - guarantees fast wiper response for dynamic calibration sequences |
| Wiper resistance | 600Ω - contributes predictable series impedance in precision current-sense or bias networks |
Pinout & Package
ISL90462WIH627-TK is housed in a 6-lead SOT-23 plastic package (JEDEC MO-178AB, pkg drawing P6.064), measuring 2.80mm × 2.60mm × 1.30mm (max height), RoHS-compliant with matte tin termination.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Supply voltage input | Power rail for internal logic and resistor array; must be decoupled locally for noise-sensitive analog use |
| GND | Ground reference | Low-side terminal of potentiometer; serves as common return for wiper and RH paths |
| U/D | Direction control | High = wiper moves toward RH; Low = wiper moves toward GND; edge-triggered on rising edge when CS active |
| CS | Chip select | Active-low enable; wiper position latched into volatile memory on CS rising edge; high state places device in 0.3µA standby |
| RW | Wiper output | Variable node connecting to one of 32 tap points; presents 600Ω series resistance and 25pF capacitance to load |
| RH | High terminal | Uncommitted end of resistor array; tied to VDD or external voltage source to form adjustable voltage divider |
Key Features
| Feature | Design Value |
|---|---|
| Volatile XDCP architecture | Eliminates nonvolatile memory wear-out and write-cycle limitations; ideal for frequent recalibration in field-deployed instruments |
| 2-pin serial interface | Reduces PCB routing complexity vs SPI/I²C; requires only two GPIOs and no clock generation logic |
| Low-power standby mode | 0.3µA supply current when CS high enables always-on calibration capability in energy-harvesting sensor nodes |
| Monotonic wiper movement | Guarantees no overshoot or wraparound at extremes-critical for closed-loop bias control where endpoint stability is required |
| Industrial temperature range | -40°C to +85°C operation validated per JEDEC JESD22-A104, supporting deployment in automotive cabin and factory-floor environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digitally controlled potentiometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD5160BRJZ-10-R7 | 32-tap, 10kΩ, SPI interface, 50ppm/°C tempco, SC-70-6 package | Requires 3-wire SPI control instead of 2-pin UP/DN; higher tempco increases drift in wide-temp industrial use | Choose when existing design uses SPI peripherals and board layout already accommodates SC-70 footprint |
| MCP4017T-103E/CH | 64-tap, 10kΩ, I²C interface, 100ppm/°C tempco, SOT-23-6 package | I²C bus contention risk in noisy environments; higher tempco degrades long-term calibration holdability | Prefer when system-level I²C infrastructure exists and precision tempco is secondary to tap count |
Compared with AD5160BRJZ-10-R7 and MCP4017T-103E/CH, the ISL90462WIH627-TK offers superior thermal stability (±35ppm/°C vs ≥50ppm/°C) and minimal GPIO overhead (2 pins vs ≥3), making it optimal for compact, thermally demanding sensor calibration systems where deterministic wiper behavior is critical.

FAQ
What is the maximum supply voltage rating for the ISL90462WIH627-TK?
The ISL90462WIH627-TK has an absolute maximum VDD rating of +7V, but its recommended operating range is 2.7V to 5.5V. Operating above 5.5V risks violating the specified DCP terminal voltage limit and may cause irreversible damage to the internal CMOS switches or resistor array. Always ensure VDD stays within the 2.7V–5.5V window for reliable operation of the ISL90462WIH627-TK.
Does the ISL90462WIH627-TK retain wiper position after power cycling?
No, the ISL90462WIH627-TK uses volatile memory only; wiper position resets to default (typically mid-scale or last-latched value depending on initialization sequence) upon power loss. It does not contain EEPROM or flash storage. System firmware must reprogram the desired tap position each time power is applied to ensure correct analog settings for the ISL90462WIH627-TK.
Can the ISL90462WIH627-TK be used as a 3-terminal voltage divider?
Yes, the ISL90462WIH627-TK supports 3-terminal operation: connect RH to a voltage source (e.g., VDD), GND to ground, and RW as the adjustable output node. This configuration forms a programmable voltage divider where the output voltage scales linearly with wiper position. The ISL90462WIH627-TK's 600Ω wiper resistance and 25pF capacitance must be accounted for in high-impedance or high-frequency load designs.
What is the wiper settling time specification for the ISL90462WIH627-TK?
The ISL90462WIH627-TK specifies a maximum output settling time of 1µs after a wiper step change, measured from U/D edge to RW voltage stabilization within final value ±0.1%. This timing applies across the full -40°C to +85°C temperature range and ensures rapid calibration updates in real-time sensor compensation loops using the ISL90462WIH627-TK.
Is the ISL90462WIH627-TK RoHS compliant and lead-free?
Yes, the ISL90462WIH627-TK is RoHS compliant and features 100% matte tin plate termination finish. It meets IPC/JEDEC J-STD-020 moisture sensitivity level requirements for Pb-free reflow profiles and is compatible with both SnPb and Pb-free soldering processes. The "TK" suffix denotes tape-and-reel packaging, and the device carries Intersil's Pb-Free Plus Anneal qualification for reliability-critical applications.
