New 32-bit stereo DAC chip for audio applications

Mouser Electronics, Inc. now offers the new BD34302EKV MUS-IC series 32-bit stereo audio DAC chip from ROHM Semiconductor. The DAC chip provides high-quality spatial audio for smart speakers, digital audio players and high-resolution audio applications.

The DAC chip integrates ROHM's exceptional sound quality design technology, including high sampling data weighted averaging (DWA), that improves THD performance (SNR 130dB) while providing higher resolution and enhanced natural sound quality with an exclusive HD monaural mode. The chip also provides an automatic mode-switching function that enables users to easily switch between PCM and direct stream digital (DSD), sampling frequencies (32khz to 1536khz), two channels of finite impulse-response (FIR) filters, and two different DWA algorithms.

This DAC chip produces spatial reverberation, quietness, and dynamic range while preserving the natural 'texture' of musical instruments with direct stream digital frequencies (2.8MHz, 5.6MHz, 11.2MHz or 22.5MHz) in two-channel stereo, single-channel mono or HD mono. Multi-bit data input and high sampling frequency make the chip the most versatile converter in its class.

The ROHM Semiconductor BD34302EKV evaluation board, also available from Mouser, provides a complete platform for easy demonstration and prototyping with the BD34302EKV MUS-IC DAC chip. The evaluation board includes a USB 2-wire conversion board, allowing simple connection to a PC running the included HDAC Control software.
