AKM Semiconductor Inc. AK5357VT

Description
The AK5357 is a stereo A/D Converter with a wide sampling rate range of 4kHz to 96kHz, making it suitable for multimedia audio systems. It employs Enhanced dual bit AΣ techniques to achieve high accuracy and low cost. The AK5357 requires no external components due to its single-ended analog inputs. It supports two audio interface formats (MSB justified and I²S) for compatibility with various systems.
