Product details
Overview
ISL90462UIE627Z-TK from Intersil is a volatile, single-channel, 32-tap digitally controlled potentiometer (XDCP™) with 50kΩ end-to-end resistance, 2.7V–5.5V supply range, ±35ppm/°C tempco, and SC-70-6 package. It functions as a programmable resistor for analog biasing and gain control in space-constrained industrial sensor interfaces.
For engineers reviewing the ISL90462UIE627Z-TK datasheet, ISL90462UIE627Z-TK pinout, ISL90462UIE627Z-TK application, or ISL90462UIE627Z-TK equivalent, key selection criteria include wiper resolution (1/31 RTOT), low standby current (0.3µA), Up/Down interface simplicity, and compatibility with 3V/5V logic-level control signals.
Technical Context
The ISL90462UIE627Z-TK implements a 31-element resistor ladder with electronically switched wiper access at 32 discrete tap points. Wiper position is updated synchronously on rising edges of the U/D signal while CS is asserted low, with volatile storage retaining position only during active operation.
Its architecture supports direct replacement of mechanical potentiometers in closed-loop analog circuits where digital adjustment, repeatability, and immunity to vibration or contamination are required. The device operates without external clock or serial protocol overhead-only two GPIOs (U/D and CS) are needed for full control.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RTOTAL | 50kΩ - sets full-scale resistance range for voltage divider or bias network design |
| Wiper Resolution | 32 taps - provides 31 equal steps (1/31 × RTOTAL ≈ 1.61kΩ per step) |
| VDD Range | 2.7V to 5.5V - enables direct interface with 3.3V and 5V microcontroller I/O |
| Tempco | ±35ppm/°C typical - ensures stable resistance ratio over -40°C to +85°C operating range |
| Standby Current | 0.3µA max - minimizes system power draw when potentiometer is idle |
| Wiper Resistance | 600Ω max - limits insertion error and nonlinearity in precision divider configurations |
| Settling Time | 1µs - guarantees fast analog output stabilization after wiper movement |
Pinout & Package
ISL90462UIE627Z-TK is housed in a Pb-free 6-lead SC-70 package (JEDEC MO-203AB, Intersil P6.049), measuring 2.15mm × 1.35mm × 0.95mm with gull-wing leads and pin 1 index area.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 VDD | Positive supply input | Must be decoupled locally; powers internal logic and resistor array |
| 2 GND | Ground reference | Serves as low-side terminal (RL) of potentiometer; return path for all currents |
| 3 U/D | Direction control input | Rising edge increments/decrements wiper position when CS is low |
| 4 CS | Chip select enable | Active-low signal that enables counter updates and enters standby when high |
| 5 RW | Wiper output | Provides variable resistance node between RH and GND; connects to load or feedback path |
| 6 RH | High terminal | Fixed end of resistor array; tied to external voltage source in divider configuration |
Key Features

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; 64-tap resolution; 50kΩ RTOT | Retains wiper position after power loss; requires SPI controller and additional firmware overhead | Choose when persistent settings are mandatory and SPI resources are available |
| MCP4017T-503E/CH | Volatile design; I²C interface; 32-tap; 50kΩ RTOT; higher wiper resistance (1000Ω) | Requires I²C bus and address management; less suitable for ultra-low-power or GPIO-limited designs | Prefer when existing system uses I²C and board layout accommodates larger SOT-23-6 footprint |
Compared with AD5160BRJZ-50-R7 and MCP4017T-503E/CH, the ISL90462UIE627Z-TK offers lowest pin count, minimal MCU resource usage (2 GPIOs), and smallest SC-70 footprint-making it optimal for cost-sensitive, space-constrained, and ultra-low-power analog trimming tasks where volatile operation is acceptable.

FAQ
What is the function of the CS pin on the ISL90462UIE627Z-TK?
The CS (Chip Select) pin on the ISL90462UIE627Z-TK is an active-low enable signal. When CS is low, the device accepts U/D input transitions to move the wiper. When CS returns high, the current wiper position is latched into volatile memory and the device enters standby mode, drawing only 0.3µA. This dual-role pin simplifies control timing and reduces power consumption in static configurations.
Does the ISL90462UIE627Z-TK retain its wiper position after power cycling?
No, the ISL90462UIE627Z-TK is a volatile digitally controlled potentiometer. Its wiper position resets to a default state (typically mid-scale or last-set value depending on internal reset behavior) upon power-up. System firmware must reinitialize the wiper position via U/D/CS commands after each power cycle-this is inherent to its architecture and confirmed in the FN8230 datasheet.
What is the maximum voltage that can be applied across RH and RW terminals of the ISL90462UIE627Z-TK?
The ISL90462UIE627Z-TK specifies RH and RW terminal voltages from 0V to VDD (2.7V–5.5V). Applying voltage beyond this range violates the Absolute Maximum Rating for "Voltage on RH, RL terminals" and risks latch-up or permanent damage. For use as a voltage divider, ensure both RH and RW remain within the VDD–GND window at all times.
Can the ISL90462UIE627Z-TK be used in a rheostat (two-terminal) configuration?
Yes, the ISL90462UIE627Z-TK supports rheostat operation by connecting GND and RW together (or RH and RW) and using the remaining two pins as variable resistance terminals. However, wiper current must stay within ±0.6mA, and total power dissipation must not exceed 1mW-designs must verify compliance under worst-case voltage and resistance conditions.
Is the ISL90462UIE627Z-TK RoHS compliant and lead-free?
Yes, the ISL90462UIE627Z-TK is marked "Pb-Free Plus Anneal" and fully RoHS compliant per the datasheet note. It uses 100% matte tin plating and RoHS-compliant molding compounds, qualified for both SnPb and Pb-free reflow profiles (MSL level per IPC/JEDEC J-STD-020), and carries the "Z" suffix denoting Pb-free packaging.
