Advanced series of DAC chips enable expressive playback of classical music


Advanced series of DAC chips enable expressive playback of classical music
ROHM has released the new BD34301EKV, a 32bit D/A converter IC created for high fidelity audio equipment – capable of high-resolution playback of audio sources. At the same time, the company also offers BD34301EKV-EVK-001 evaluation boards to test the performance of its new IC.
The DAC chip, developed as part of the company s high-grade MUS-IC series, presents the pinnacle of audio ICs, emphasises ‘spatial resonance’, ‘sense of scale’ and ‘quietness’, which are qualities essential for reproducing classical music. Original sound quality design technology makes it feasible to successfully reproduce the target sound quality by including a circuit in the signal processing block to check audio quality. Concurrently, class-leading low noise and distortion (130dB SN ratio, -115dB THD+N) give the high performance demanded by high fidelity audio equipment. Finally, the customisable digital filt ....

32bit DAC for Hi-Fi


32bit DAC for Hi-Fi
Rohm has announced a 32bit mono/stereo Hi-Fi DAC, claiming for it a typical signal to noise ratio of 130dB and -115dB THD+noise.
Called BD34301EKV, it can accept PCIM inputs from 32 to 768kHz and DSD at 2.8, 5.6, 11.2 or 22.4MHz. FIR filters are provided for: PCIM sharp roll-off, PCIM slow roll-off and DSD.
The two outputs each provide differential currents, which can be converted to voltages through a pair of circuits suggested by the company (
below left). In mono mode, only one output circuit is used, fed by the DAC outputs connected in parallel to double current. ....
