Wolfson Microelectronics has an audio hub and Class-D digital input speaker amplifier chipset for smartphones and tablet PCs.
The Scotland-based firm said it tackles the audio quality issues caused by routing analogue signals over longer distances.
The WM8996 audio hub incorporates an audio mixing methodology which handles multiple audio routings and concurrent use cases.
The chip includes a digital audio interface employing Pulse Density Modulation (PDM) protocol to connect digital microphones such as the WM7210 and WM7220 in addition to digital speaker amplifiers like the new WM9082.
The WM9082 Class-D speaker amplifier has PDM input capability and provides 92dB SNR performance.
The 2.3mm sq chip can drive up to 2.5W into a 4ohm speaker.
According to the supplier, the PDM interface format eases the complexity of form-factor end product design without compromising audio quality as it provides the option to transfer data digitally.
"This avoids the loss of fidelity when routing analogue signals over longer distances," said Wolfson.
