Product details
Overview
ISL90461UIE627-TK from Intersil is a digitally controlled potentiometer (XDCP) configured as a volatile 32-tap variable resistor with 50kΩ end-to-end resistance, 2.7V–5.5V supply range, and ±35 ppm/°C tempco. It implements precision bias and gain adjustment in analog signal paths using a 2-pin Up/Down interface and SC-70-6 package.
For engineers reviewing the ISL90461UIE627-TK datasheet, ISL90461UIE627-TK pinout, ISL90461UIE627-TK application, or ISL90461UIE627-TK equivalent, key selection criteria include wiper resolution (32 taps), volatile memory behavior, RH/RL terminal configuration, low standby current (0.3µA), and compatibility with industrial temperature range (-40°C to +85°C).
Technical Context
The ISL90461UIE627-TK integrates a 31-element resistor array with electronic wiper switching controlled by CS and U/D inputs. Wiper position is stored in volatile memory only while CS is active low; counter state resets on power-up.
It operates as a 2-terminal variable resistor with RH tied internally to the wiper and RL as the low terminal. The device supports up/down incrementing at ≤1 MHz toggle rate, with 1 µs output settling time and no wraparound at tap extremes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RTOTAL | 50 kΩ - fixed end-to-end resistance defining full-scale analog adjustment range |
| Wiper Resolution | 32 taps - provides 31 discrete resistance steps between RH and RL terminals |
| Supply Voltage | 2.7 V to 5.5 V - compatible with 3.3 V and 5 V logic/system rails without level shifting |
| Tempco | ±35 ppm/°C typical - ensures stable resistance over -40°C to +85°C operating range |
| Standby Current | 0.3 µA - enables ultra-low-power operation when CS is high |
| Active Current | 25 µA max - minimal supply draw during wiper adjustment |
| Wiper Resistance | 600 Ω max - limits error contribution in precision voltage divider configurations |
Pinout & Package
ISL90461UIE627-TK uses a 6-lead SC-70 plastic package (JEDEC MO-203AB, Intersil P6.049), measuring 2.15 mm × 1.35 mm × 1.10 mm, with gull-wing leads and RoHS-compliant matte tin plating.
| 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, control signals, and RH/RL terminals |
| U/D | Direction control input | High = increment wiper toward RH; Low = decrement toward RL |
| CS | Chip select / enable | Low = active mode (wiper moves on U/D edges); High = standby (0.3 µA) |
| RL | Potentiometer low terminal | Fixed end of resistor array; forms 2-terminal variable resistance with RH |
| RH | High terminal / wiper output | Internally connected to wiper; resistance RH-to-RL varies with tap position |
Key Features
| Feature | Design Value |
|---|---|
| Volatile XDCP architecture | Wiper position resets on power cycle-ideal for applications requiring known startup state |
| 2-pin serial interface | Eliminates need for clock or data lines-reduces PCB routing complexity vs SPI/I²C pots |
| Low power standby | 0.3 µA supply current when CS is high-extends battery life in portable sensor systems |
| Industrial temperature range | -40°C to +85°C operation-supports deployment in automotive cabin, industrial PLC, and outdoor equipment |
| SC-70-6 footprint | Small 2.15 × 1.35 mm outline-enables high-density analog tuning in space-constrained designs |

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 | 10 kΩ RTOTAL, SPI interface, non-volatile EEPROM memory | Retains last wiper setting after power loss-suited for "set-and-forget" systems | Select when persistent wiper position is required; not drop-in due to different interface and memory type |
| MCP4017T-503E/CH | 50 kΩ RTOTAL, I²C interface, volatile memory, SOT-23-6 package | Requires I²C bus and address configuration-adds firmware overhead vs Up/Down simplicity | Select when existing design already uses I²C peripherals; same RTOTAL but different pinout and protocol |
Compared with AD5160BRJZ10-RL7 and MCP4017T-503E/CH, the ISL90461UIE627-TK offers lowest system-level integration effort for simple up/down adjustment, smallest SC-70 footprint among 50kΩ options, and lowest standby current-making it optimal for cost-sensitive, space-constrained, battery-aware analog tuning.

FAQ
What is the resistance tolerance and temperature coefficient of the ISL90461UIE627-TK?
The ISL90461UIE627-TK has a nominal end-to-end resistance of 50 kΩ with ±20% tolerance (40 kΩ to 60 kΩ per datasheet Table "Potentiometer Specifications"). Its typical temperature coefficient is ±35 ppm/°C, measured over the full -40°C to +85°C operating range, ensuring predictable resistance drift in thermally varying environments.
Does the ISL90461UIE627-TK retain its wiper position after power cycling?
No, the ISL90461UIE627-TK uses volatile memory only. Wiper position resets to default (typically mid-scale or last-set value depending on control sequence) upon power removal. It does not include EEPROM or non-volatile storage-this behavior is inherent to its XDCP architecture and confirmed in the "Principles of Operation" section of the FN8229.3 datasheet.
Can the ISL90461UIE627-TK be used as a 3-terminal potentiometer?
No-the ISL90461UIE627-TK is configured exclusively as a 2-terminal variable resistor. RH is internally tied to the wiper; RL is the fixed low terminal. There is no independent wiper output pin. This architecture is explicitly defined in the "Pin Descriptions" and "Principles of Operation" sections of the datasheet.
What is the maximum allowable voltage across RH and RL terminals of the ISL90461UIE627-TK?
The absolute maximum voltage across RH and RL is limited by the supply voltage: VR = RH–RL must remain within 0 V to VDD (2.7 V to 5.5 V). Exceeding VDD risks violating the "Voltage on CS, U/D and VCC with respect to GND" rating of –1 V to +7 V, and may damage the internal switches. No separate RH–RL breakdown rating is specified.
Is the ISL90461UIE627-TK RoHS compliant and lead-free?
Yes-the ISL90461UIE627-TK is Pb-Free Plus Anneal (RoHS compliant), featuring 100% matte tin plate termination finish and RoHS-compliant molding compounds. This is confirmed in the "Ordering Information" table footnote and "Pb-Free Plus Anneal Available" feature bullet of the FN8229.3 datasheet.
