ROHM Semiconductor BD34301EKV MUS-IC™ Series 32-Bit Stereo Audio DAC
ROHM Semiconductor BD34301EKV MUS-IC™ Series 32-Bit Stereo Audio DAC (Digital-to-Analog Converter) is a two-channel ΣΔ converter IC optimized for high-performance audio applications. The BD34301EKV features a 130dB SNR (Signal-to-Noise Ratio) and an extremely low -115dB THD+N (Total Harmonic Distortion plus Noise). The device can accept PCM (Pulse-Code Modulation) inputs up to 768kHZ and DSD (Direct Stream Digital) inputs up to 22.4MHz. The BD34301EKV also offers two separate Digital FIR (Finite Impulse Response) filters, enabling sound customization.
The ROHM Semiconductor BD34301EKV MUS-IC™ Series Audio DAC is offered in an HTQFP64BV package with an exposed pad for enhanced thermal performance.
