ADC / DAC Audio IP serving voice-enabled devices
We provide high-performance, compact, low power and customizable audio analog mixed-signal IP in leading foundry processes, including a wide range of ADC, DAC, CODEC and Voice Activity Detectors.
By embedding our IP, designers can meet the demanding audio requirements of voice-controlled devices, keeping BOM and integration costs under control.
Our IP portfolio serves leading-edge audio applications
The emergence of powerful voice recognition algorithms drives the growth of connected devices controlled by voice, where voice recognition and ultra-low power technologies are key to delivering the optimal user experience. The complete set of Foundation, Feature and Fabric IPs of Dolphin Integration will allow us to demonstrate fast and safely a human-machine interaction system relying on a C-Sky microcontroller-based SoC platform.
Our experience of using Dolphin Integration’s ultra-dense audio DAC has been very positive. A pure logic DAC is extremely compact at 28nm and enables to drastically reduce the industrial test duration, as structural testing such as SCAN can efficiently be applied, which is pivotal for our SoC competitiveness on the aggressive market of Set-Top Boxes.
Meeting the right balance between silicon costs, audio quality and low power consumption is a challenging task. The YANZI-A-hexADC-VD.01, a feature-rich audio ADC from Dolphin Integration, packs all these advantages into our smart speaker offering.
Remove distractions. Augment your sound experience.
Ultra low latency audio converters down to 3µs
Active Noise Cancellation allows for listening to audio content without raising the volume excessively. We provide a powerful set of converters to make high-fidelity ANC possible.
- ADC with Dynamic Range higher than 104 dB maintaining audio performance in analog mic-in mode
- Pop-up noise level as low as – 60 dBV
Ultra efficient and accurate voice command detection. Wake up when effectively required.
Audio CODEC with embedded Voice Detection
The built-in microphones in smart speakers are continuously listening for “hot keywords” followed by a command. In order to maximize the sleep state mode timeshare to limit the system power consumption, we designed audio CODEC solutions with voice activity detection capability, the Whisper Trigger IP.
- Enables ultra low power keyword spotting mode
- High Dynamic Range – up to 100 dB – to perform far-field voice recognition
Accurate sound processing. Reliable voice interaction.
Audio CODEC with high Noise Resilience
Engage seamless in-vehicle voice command and response interactions with robust noise tolerance in high temperature environment.
- High CMRR enabling in-vehicle distributed mic positioning
- Low crosstalk multi-channel CODEC
- Embedded low noise voltage regulator for enhanced resilience to power supply related noise
