AK5358
96kHz 24-Bit ∆Σ ADC
GENERAL DESCRIPTION The AK5358 is a stereo A/D Converter with wide sampling rate of 8kHz ∼ 96kHz and is suitable for consumer to professional audio system. The AK5358 achieves high accuracy and low cost by using Enhanced dual bit ∆Σ techniques. The AK5358 requires no external components because the analog inputs are single-ended. The audio interface has two formats (MSB justified, I2S) and can correspond to various systems like DTV, DVR and AV Receiver. FEATURES Linear Phase Digital Anti-Alias Filtering Single-ended Input Digital HPF for DC-Offset cancel S/(N+D): 92dB DR: 102dB S/N: 102dB Sampling Rate Ranging from 8kHz to 96kHz Master Clock: 256fs/384fs/512fs/768fs (8kHz ∼ 48kHz) 256fs/384fs (48kHz ∼ 96kHz) Input level: CMOS Master / Slave Mode Audio Interface: 24bit MSB justified / I2S selectable Power Supply: 4.5 ∼ 5.5V (Analog), 2.7 ∼ 3.6V (Digital) Ta = −20 ∼ 85°C Small 16pin TSSOP Package AK5357/59/81 Pin-compatible
