AS1108WL-T

Overview

The AS1108WL-T is a LED driver integrated circuit manufactured by ams OSRAM AG, designed for driving seven-segment displays with decimal points. It supports four-digit configurations and operates within a supply voltage range of 2.7V to 5.5V. The device draws a supply current of 330 mA and functions reliably across an operating temperature range of 0°C to 70°C. It utilizes a 20-SOIC surface-mount package with a width of 7.50mm. Communication is facilitated through standard digital interfaces including 4-wire serial, Microwire, QSPI, and SPI protocols.

Feature Summary

• Supports direct driving of 7-segment LED displays with decimal point configuration
• Compatible with multiple digital serial communication interfaces for flexible system integration
• Operates on a single power supply voltage ranging from 2.7V to 5.5V

Applications

• Seven-segment display drivers in consumer electronics
• Digital readout systems requiring serial interface control
• Industrial instrumentation panels

Procurement Notes

Verify the specific suffix 'T' against the official datasheet to confirm tape-and-reel packaging requirements. Confirm RoHS compliance status and MSL rating prior to assembly. Check for End-of-Life notices as the base part number may have discontinuation alerts. Ensure the 20-SOIC footprint matches the PCB design guidelines provided in the manufacturer's documentation.

Selection Notes

Select this component when a dedicated driver for 4-digit 7-segment displays is required with serial interface compatibility. Consider the 2.7V to 5.5V input range for low-voltage applications. Verify that the 330 mA supply current meets the system power budget. The 20-SOIC package is suitable for surface-mount assembly processes.

Part Context

The AS1108WL belongs to the AS1108 family of LED display drivers from ams OSRAM. This series provides solutions for managing multi-digit 7-segment displays without requiring complex external logic. The WL variant specifically denotes the 20-SOIC package option. These components are typically used in applications where space efficiency and simplified interfacing are prioritized over high-current channel capabilities.
