ams' AS3435 are speaker drivers with ambient noise cancelling function for headsets, headphones, or ear pieces. They are intended to improve the quality of listening to music, phone conversations, and other similar activities by reducing background ambient noise. The full analog implementation will allow a low power consumption, lowest system BOM cost, and a natural received voice enhancement. This can be difficult to achieve with DSP implementations, but is designed to be easily applied to existing architectures.

The AS3435 can be used in different configurations for the best trade-off of required filtering functions, mechanical designs, and noise cancellation. There is an operating temperature range of -20°C to +85°C and it comes in a small 5x5 36-QFN package. The AS3435 is ideal for noise cancellation for consumer, automotive, and industrial audio applications.
