AK4390
Ultra Low Latency 32-Bit ΔΣ DAC
GENERAL DESCRIPTION The AK4390 is a high performance stereo DAC capable of sampling up to 216kHz including a 32-bit digital filter. The modulator uses AKM's multi-bit architecture, delivering wide dynamic range while preserving linearity for improved THD+N performance. The AK4390 has fully differential switched-cap filter outputs, removing the need for AC coupling capacitors and increasing performance for systems with excessive clock jitter. The AK4390 accepts 192kHz PCM data, ideal for a wide range of applications including DVD-Audio, high end sound cards, digital audio Firewire and USB interface boxes, and digital mixers. FEATURES 128-times Oversampling Sampling Rate: 30kHz 216kHz 32Bit 8x Digital Filter Ripple: ±0.005dB, Attenuation: 100dB Low latency option: 7/fs High Tolerance to Clock Jitter Low Distortion Differential Output Digital De-emphasis for 32, 44.1, 48kHz sampling Soft Mute Digital Attenuator (255 levels and 0.5dB step) THD+N: 103dB DR, S/N: 120dB Audio Format: 24/32bit MSB justified, 16/20/24/32bit LSB justified, I2S Master Clock: 30kHz ~ 32kHz: 1152fs 30kHz ~ 54kHz: 512fs or 768fs 30kHz ~ 108kHz: 256fs or 384fs 108kHz ~ 216kHz: 128fs or 192fs Power Supply: 5V ± 5% TTL Level Digital I/F Package: 30pin VSOP
