AS1108WL-Z

Overview

The AS1108WL-Z is a discontinued LED driver IC manufactured by ams OSRAM AG. It features a 20-SOIC surface-mount package and supports 4-digit, 7-segment plus decimal point displays. The device operates on a supply voltage range of 2.7V to 5.5V with a typical supply current of 330 mA. It utilizes digital interfaces including 4-wire serial, Microwire, QSPI, and SPI for control. The component functions within an operating temperature range of 0°C to 70°C and holds RoHS compliance status.

Feature Summary

Supports 4-digit, 7-segment LED displays with decimal point configuration
Compatible with multiple digital interface protocols including SPI and Microwire
Designed for surface-mount installation in compact electronic assemblies

Applications

Digital display drivers for consumer electronics
Instrumentation panel readouts
Industrial control system indicators

Procurement Notes

Verify availability carefully as the AS1108WL series has been officially declared obsolete by the manufacturer. Confirm specific suffix requirements with suppliers, noting that ordering suffixes do not inherently alter functional specifications unless explicitly stated in official documentation. Source only from authorized channels to ensure authenticity and traceability.

Selection Notes

Select this component only if legacy compatibility with existing 20-SOIC footprints and SPI/Microwire interfaces is required. Evaluate alternative modern drivers if new designs are permitted, considering updated manufacturing processes and longer-term supply stability. Ensure power supply constraints align with the specified 2.7V to 5.5V operational range.

Part Context

This part belongs to the AS1108 family of LED drivers designed for segment-based display applications. The WL variant specifically denotes the 20-SOIC package configuration. The broader product line focuses on providing efficient drive solutions for multi-digit numeric displays in various electronic devices requiring reliable segment illumination control.
