ISL90462UIH627Z-TK

Digital Potentiometers Overview

The ISL90462UIH627Z-TK is a digital potentiometer IC manufactured by Renesas Electronics Corporation, formerly Intersil. It features a 32-tap resistive element with a nominal resistance of 50 kOhms. The device utilizes an I²C-compatible serial interface for setting the wiper position. It operates within a supply voltage range typically associated with its family and includes non-volatile memory to retain the wiper setting upon power cycle. The component is housed in a compact SOT-23-6 surface-mount package, designed for applications requiring precise, software-adjustable resistance values.

Digital Potentiometers Feature Summary

• 32-tap digital potentiometer with 50 kOhm total resistance
• I²C serial interface for wiper control
• Non-volatile memory retains settings after power loss
• SOT-23-6 surface-mount package

Digital Potentiometers Applications

• Audio volume control and tone adjustment
• Programmable gain amplifier offset calibration
• Voltage reference trimming
• LCD bias voltage adjustment

Digital Potentiometers Procurement Notes

Verify the specific suffix 'UIH627Z-TK' against official Renesas documentation to confirm tape-and-reel packaging and temperature grade. Ensure the 50 kOhm resistance value matches the circuit design requirements, as other variants in the ISL9046 series offer different resistance values such as 10 kOhm or 100 kOhm.

Digital Potentiometers Selection Notes

Select this part when a 50 kOhm digital potentiometer with I²C control is required. Compare pinout compatibility with legacy analog potentiometers if replacing mechanical components. Confirm that the operating voltage range of the digital potentiometer aligns with the system's logic levels and supply rails.

Digital Potentiometers Part Context

The ISL9046 series comprises volatile and non-volatile digital potentiometers. The ISL90462 variant specifically denotes the 50 kOhm resistance value. The 'TK' suffix typically indicates tape-and-reel packaging for automated assembly. This component belongs to the broader portfolio of programmable resistor solutions used for calibration and adjustment in embedded systems.

Digital Potentiometers Replacement Considerations

Direct replacements must match the 50 kOhm resistance, I²C interface, and SOT-23-6 package. Verify if the replacement supports non-volatile storage if power-down retention is critical. Check for pin-to-pin compatibility with existing PCB layouts.
