Introduction

The AK4112B is a digital audio receiver (DIR) compatible with 96kHz, 24bits. The channel status decoding supports both consumer and professional modes. The AK4112B can automatically detect a Non-PCM bit stream. When combined with an AK4527B multi channel codec, the two chips provide a system solution for AC-3 applications. The dedicated pins or a serial μP I/F can control the mode setting. The small package, 28pin SSOP saves the board space.
