Product details
Overview
ISL90462UIE627-TK from Intersil is a volatile digitally controlled potentiometer (XDCP™) configured as a 50kΩ end-to-end variable resistor with 32 wiper tap points, 2-pin UP/DN interface, and operation from 2.7V to 5.5V supply. It serves as an electronic replacement for mechanical trimmers in precision bias and gain adjustment circuits.
For engineers reviewing the ISL90462UIE627-TK datasheet, ISL90462UIE627-TK pinout, ISL90462UIE627-TK application, or ISL90462UIE627-TK equivalent, key selection considerations include its SC-70-6 package, ±35ppm/°C tempco, 25µA max active current, volatile memory architecture, and compatibility with low-power industrial sensor calibration and LCD contrast control systems.
Technical Context
The ISL90462UIE627-TK implements a 31-element resistor array with electronically switched wiper access at 32 discrete tap points. Wiper position is updated via edge-triggered UP/DN signals under active CS control, with no internal clock or serial protocol required.
It operates as a 2-terminal variable resistor or 3-terminal voltage divider depending on external connections: RH connects to reference voltage, GND serves as low terminal, and RW delivers the wiper output. The device enters 0.3µA standby mode when CS is high, and settling time after wiper movement is 1µs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RTOTAL | 50kΩ ±20% - defines full-scale resistance range for gain/bias scaling accuracy |
| Wiper taps | 32 discrete positions - enables 31-step resolution for fine analog tuning |
| VDD range | 2.7V to 5.5V - supports direct interface with 3.3V and 5V logic/system rails |
| Tempco | ±35ppm/°C typical - ensures stable resistance ratio over -40°C to +85°C industrial range |
| Active current | 25µA max - enables battery-powered or ultra-low-power sensor front-end use |
| Standby current | 0.3µA - allows persistent low-power state during system sleep modes |
| Wiper resistance | 600Ω max - limits voltage error and signal attenuation in precision divider configurations |
Pinout & Package
ISL90462UIE627-TK is housed in a 6-lead SC-70 package (JEDEC MO203AB, pkg drawing P6.049), measuring 2.15mm × 1.35mm × 0.95mm, with gull-wing leads and RoHS-compliant matte tin plating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 VDD | Positive supply input | Accepts 2.7V–5.5V; powers internal CMOS logic and switching network |
| 2 GND | Ground reference | Serves as low-side terminal of potentiometer; must be connected to system ground |
| 3 U/D | Direction control input | High = increment wiper toward RH; Low = decrement toward GND; edge-triggered |
| 4 CS | Chip select | Low = enable wiper update; High = latch current position and enter 0.3µA standby |
| 5 RW | Wiper output | Delivers analog voltage proportional to wiper position; connects to feedback or bias node |
| 6 RH | High terminal | Connects to reference voltage source; forms upper leg of voltage divider with GND/RW |
Key Features
| Feature | Design Value |
|---|---|
| Volatile XDCP architecture | Wiper resets to default (mid-scale or last-latched) on power-up; eliminates nonvolatile write endurance concerns |
| 2-pin UP/DN interface | Requires only two GPIOs-no I²C/SPI controller needed-reducing MCU pin count and firmware overhead |
| Low 25µA active current | Enables continuous real-time trimming in portable instrumentation without significant battery drain |
| 600Ω max wiper resistance | Maintains <0.1% gain error in 50kΩ-divider applications where wiper loading affects accuracy |
| SC-70-6 footprint | Provides same board area as SOT-23-6 but with tighter pitch (0.65mm vs 0.95mm), supporting higher-density layouts |

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-50-R7 | Nonvolatile EEPROM memory; SPI interface; 50kΩ; SOT-23-8 | Retains wiper setting across power cycles; requires SPI master and additional PCB routing | Choose for systems requiring power-loss immunity and infrequent reconfiguration |
| MCP4017T-503E/CH | Volatile design; I²C interface; 50kΩ; SOT-23-8; 64-tap resolution | Higher resolution but larger footprint and I²C bus dependency; lacks SC-70 option | Choose when I²C infrastructure exists and finer 64-step granularity is needed |
Compared with AD5160BRJZ-50-R7 and MCP4017T-503E/CH, the ISL90462UIE627-TK offers the smallest board footprint (SC-70-6), lowest active current (25µA), and simplest 2-pin control-ideal for space-constrained, low-power, GPIO-limited designs where power-cycle persistence is not required.

FAQ
What is the resistance tolerance and temperature coefficient of the ISL90462UIE627-TK?
The ISL90462UIE627-TK has a nominal end-to-end resistance of 50kΩ with ±20% initial tolerance and a typical temperature coefficient of ±35ppm/°C over -40°C to +85°C. This ensures predictable resistance drift in industrial environments and supports accurate gain/offset calibration without frequent recalibration.
Does the ISL90462UIE627-TK retain its wiper position after power cycling?
No, the ISL90462UIE627-TK uses volatile memory and resets its wiper position on power-up. It latches the current wiper setting only while CS is high, and loses that state when VDD is removed. For nonvolatile retention, consider alternatives like the AD5160BRJZ-50-R7.
What is the maximum voltage that can be applied across RH and RW terminals of the ISL90462UIE627-TK?
The ISL90462UIE627-TK specifies RH and RW terminal voltages from 0V to VDD (2.7V–5.5V). Applying voltage beyond this range risks exceeding absolute maximum ratings and may damage the internal switches. The device is not rated for bipolar or AC-coupled operation.
Can the ISL90462UIE627-TK be used as a 3-terminal voltage divider?
Yes-the ISL90462UIE627-TK supports 3-terminal operation: connect RH to a reference voltage, GND to system ground, and use RW as the adjustable output. This configuration enables precise voltage division for biasing, level-shifting, or feedback networks in analog signal chains.
What is the settling time and wiper resistance specification for the ISL90462UIE627-TK?
The ISL90462UIE627-TK has a 1µs output settling time after wiper movement and a maximum wiper resistance of 600Ω. These values ensure fast, low-error analog updates in closed-loop systems-critical for maintaining stability in laser driver or sensor amplifier feedback paths.
