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.
