24Bit 96kHz Σ ADC
AK5357
GENERAL DESCRIPTION The AK5357 is a stereo A/D Converter with wide sampling rate of 4kHz 96kHz and is suitable for multimedia audio system. The AK5357 achieves high accuracy and low cost by using Enhanced dual bit Σ techniques. The AK5357 requires no external components because the analog inputs are single-ended. The audio interface has two formats (MSB justified, I2S) and can correspond to many systems like Karaoke, surround.
FEATURES Stereo Σ ADC On-Chip Digital Anti-Alias Filtering Single-ended Input Digital HPF for DC-Offset cancel S/(N+D): 88dB@5V, 86dB@3V for 48kHz DR: 102dB@5V, 100dB@3V for 48kHz S/N: 102dB@5V, 100dB@3V for 48kHz Sampling Rate Ranging from 4kHz to 96kHz Master Clock: 256fs/384fs/512fs/768fs (4kHz 48kHz) 256fs/384fs (48kHz 96kHz) Input level: TTL/CMOS selectable Master / Slave Mode Audio Interface: 24bit MSB justified / I2S selectable Power Supply: 2.7 5.5V Ta = 40 85°C (VT), 20 85°C (ET) Small 16pin TSSOP Package AK5381 Pin-compatible
