AS1108WL-T-Z

Overview

The AS1108WL-T-Z is a seven-segment LED display driver manufactured by ams OSRAM AG. It supports four-digit displays with decimal points and operates on a supply voltage range of 2.7V to 5.5V. The device draws 330 mA of supply current and features a 20-SOIC surface-mount package. It communicates via 4-wire serial, Microwire, QSPI, or SPI interfaces. The component is rated for an operating temperature between 0°C and 70°C. This specific part number variant is marked as obsolete.

Feature Summary

• Supports 7-segment plus decimal point display configurations
• Compatible with multiple serial communication protocols including SPI and Microwire
• Designed for surface-mount installation in compact electronic assemblies

Applications

• Seven-segment LED display systems
• Digital readout instrumentation
• Consumer electronics control panels

Procurement Notes

Verify the obsolete status of this component before integration into new designs. Confirm that the -T-Z suffix denotes the specific tape-and-reel packaging variant rather than a functional change. Ensure compatibility with existing PCB footprints for the 20-SOIC package. Check for available replacement components from the manufacturer's portfolio if long-term supply is required.

Selection Notes

Select this driver for applications requiring direct interface with 4-digit 7-segment displays. Verify that the system logic levels match the supported serial interfaces. Consider the thermal characteristics of the SOIC package relative to the ambient operating environment. Evaluate the power consumption against the available supply voltage headroom within the specified 2.7V to 5.5V range.

Part Context
