Description

Premium ADCs
VELVET SOUNDVERITA The AK5397EQ is a 32bit, 768kHz sampling 2ch A/D Converter for professional digital audio systems. The modulator in the AK5397EQ uses the advanced multi bit architecture. This architecture achieves the wide dynamic range and wide bandwidth, while keeping superior distortion characteristics. The AK5397 performs 127dB dynamic range, and the device is suitable for professional studio equipment such as digital mixer and digital VTR. The operating voltages support analog 5V and digital 3.3V, so it is easy to I/F with 3.3V logic IC.
