ISL90462UIE627Z-TK

Digital Potentiometers Overview

The ISL90462UIE627Z-TK is a dual-channel digital potentiometer manufactured by Renesas Electronics Corporation. It features two independent wiper controls, each with 32 tap positions and a nominal resistance of 50 kΩ. The device operates on a supply voltage range of 2.7V to 5.5V and utilizes an Up/Down (U/D) and Chip Select (CS) interface for position adjustment. It employs volatile memory to retain settings during operation and is housed in a 6-lead SOT-23 package.

Digital Potentiometers Feature Summary

• Dual-channel configuration with independent 32-tap control per channel
• Nominal resistance of 50 kΩ with ±20% tolerance
• Operates within a 2.7V to 5.5V supply voltage range
• Uses volatile memory for wiper position storage

Digital Potentiometers Applications

• Audio volume control circuits requiring dual-channel adjustment
• Variable gain amplifier configurations
• Programmable biasing networks in sensor interfaces
• Voltage reference trimming in measurement systems

Digital Potentiometers Procurement Notes

Verify the specific suffix 'Z' for RoHS compliance status and '-TK' for tape-and-reel packaging quantity directly with the manufacturer or authorized distributors. Confirm lead times and availability as this component may be subject to discontinuation or lifecycle changes. Ensure the volatile memory requirement aligns with system power management strategies.

Digital Potentiometers Selection Notes

Select this model when dual-channel resistive adjustment is required within a compact SOT-23 footprint. The 50 kΩ resistance value suits applications needing higher impedance than standard 10 kΩ variants. Verify that the system can tolerate loss of calibration data upon power cycling due to volatile memory. Ensure the U/D interface logic levels are compatible with the controlling microcontroller.

Digital Potentiometers Part Context

This part belongs to the ISL9046x family of digital potentiometers, which offers multiple resistance values and interface options. The 'ISL90462' designation specifically indicates the dual-channel variant, distinguishing it from single-channel models like the ISL90461. The 'UIE' code typically denotes the 50 kΩ resistance value and SC-70/SOT-363 compatible packaging style within the Intersil/Renesas nomenclature.

Digital Potentiometers Replacement Considerations

Direct pin-compatible substitutes include other dual-channel digital potentiometers from the same family, such as the ISL90462WIH627Z-TK if a different resistance value (e.g., 10 kΩ) is acceptable. Cross-vendor replacements require careful verification of interface protocols, voltage ranges, and package dimensions.
