AK5394A Datasheet | Asahi Kasei Microdevices

DESCRIPTION The AK5394A is a 24bit, 192k Hz sampling 2ch A/D Converter for professional digital audio systems. The modulator in the AK5394A uses the new developed advanced multi bit architecture. This new architecture achieves the wide dynamic range and wide bandwidth, while keeping superior distortion characteristics. The AK5394A performs 123d B dynamic range, so the device is suitable for professional studio equipment such as digital mixer, digital VTR etc. The operating voltages support analog 5V and digital 3.3V, so it is easy to I/F with 3.3V logic IC.
