AS3415 analog ANC speaker driver features ultra-low power
consumption and industry-best noise attenuation
ams AG (SIX:AMS), a leading provider of high performance sensors
and analog ICs, today announced that the earphones supplied with
the new Z1 smartphone from ZUK use the AS3415, an analog speaker
driver from ams offering outstanding noise cancellation and very
low power consumption.
Benefiting from advanced analog semiconductor technology
proprietary to ams, the AS3415 Active Noise Cancellation (ANC)
speaker driver provides impressive noise reduction of up to 30 dB
over a wide audio frequency bandwidth of 3.5kHz. The device’s
typical power consumption in normal operation is just 10mW with a
1.5V supply. In addition, the speaker driver offers an internal
bypass mode with zero power consumption, disabling the
noise-cancellation function while maintaining the audio output to
the speakers.
In the Z100 in-ear headset, an accessory supplied with the Z1
smartphone launched by ZUK on 11 August 2015, the AS3415 helps to
produce a high-fidelity audio output undisturbed by ambient noise.
This provides a more pleasing and comfortable listening experience,
whether the user is enjoying music, video or other content, or
taking part in a voice call.
The Android™-based Z1 is ZUK’s flagship product, and the Z100
headset is expected to enhance the phone’s consumer appeal because
of its combination of audio quality, sleek design and new
technology: it is the first ANC headset in the world to feature the
new USB Type-C connector rather than the traditional 3.5mm audio
jack.
Since power is supplied to the noise-cancellation circuit from
the phone’s battery via this USB connection, there is no need for a
separate battery in the headset itself, enabling ZUK to realize an
extremely small and light design that is comfortable for the user
to wear.
In addition, the Z100 has a configurable noise-cancellation
feature, giving the user a choice of noise-cancellation profiles
selectable on the phone’s touchscreen. This enables the user to
adjust the bandwidth and amplitude of the noise attenuation
provided by the AS3415 depending on the way they are using the
phone and the environment in which they are using it.
‘The Z100 headset offers an attractive and must-have accessory
for ZUK Z1 smartphone users as it combines sleek design with
near-zero background noise, thanks to ams’ AS3415’s active
noise-cancelation technology. We are delighted to have partnered
with ams on the Z100 development - the company offers comprehensive
support, outstanding ANC performance along with unparalleled
expertise in mechanical and filter design,’ said Mr Icer Liu,
Director of the Accessory Business of ZUK.
‘The AS34x5 is a fully integrated, analog ANC solution for
headsets, headphones and ear pieces. Thanks to its ultra-low power
consumption, cost-saving bill of materials and superior audio
quality, the ams ANC portfolio provides a benchmark for integrated
solutions targeting the ANC market,’ said Oliver Jones, Director of
the Audio Sensors business line at ams.
The AS3415 is available immediately in production volumes. An
evaluation kit for the AS3415 ANC speaker driver is available
online from ams. For further information on the AS3415 and to
