AS3412-EWLT

Overview

The AS3412-EWLT is a Class AB audio amplifier IC featuring integrated active noise cancellation for headset applications. It operates on a 1.6V to 1.8V supply and delivers 50mW per channel into a 16-ohm load. The device utilizes a fully analog implementation to minimize power consumption and system BOM cost while enhancing received voice quality. It is housed in a compact 25-WLCSP package measuring 2.5x2.5 mm, suitable for surface mount installation within a -20°C to 85°C operating temperature range.

Feature Summary

Integrates ambient noise cancelling function to reduce background noise for improved audio clarity
Utilizes fully analog implementation for lowest power consumption and natural voice enhancement
Includes internal OTP-ROM for optional storage of microphone gain calibration settings

Applications

Headsets
Headphones
Ear pieces

Procurement Notes

Verify component authenticity through authorized channels as the AS3412-EWLT is listed as obsolete by the manufacturer. Confirm specific revision levels and packaging details against current distributor listings. Ensure compatibility with existing headset architectures before procurement. Check for alternative sourcing options if original manufacturing lines are closed.

Selection Notes

Select this component for designs requiring low-power, fully analog active noise cancellation in small form factors. It targets feed-forward topologies effective up to 2-3 kHz. Consider the 25-WLCSP package constraints and verify that the 1.6V to 1.8V supply voltage aligns with the target battery or power management system requirements.

Part Context

The AS3412 belongs to the AS3412 series of ultra-small speaker drivers developed by ams OSRAM. This series focuses on improving listening quality in portable audio devices by reducing ambient noise without complex digital signal processing. The EWLT suffix denotes the specific WLCSP package variant optimized for space-constrained mobile and wearable audio applications.
