AK4414

[AK4414] AK4414 High Performance 120dB 32-Bit 4ch DAC GENERAL DESCRIPTION AK4414 is a 32-bit DAC, which corresponds to BD systems. An internal circuit includes newly developed 32bit Digital Filter for better sound q uality achiev ing low distortion charac teristics and wide dynamic range. The AK4414 has full differential SCF outputs, removing the need for AC coupling capacitors a nd increasing performance for systems with excessive clock jitter. The AK4414 accepts 216kHz PCM d ata and 1-bit DSD data, ideal for a wide range of applications including DVD-Audio and SACD. FEATURES 128x Over sampling Sampling Rate: 30kHz ∼ 216kHz 32Bit 8x Digital Filter - Ripple: ±0.005dB, Attenuation: 80dB - High Quality Sound Short Delay Option; GD=7/fs and GD=5.5/fs - Sharp Roll-Off Filter - Slow Roll-Off Filter High Tolerance to Clock Jitter Low Distortion Differential Output DSD data input Digital De-emphasis for 32, 44.1, 48kHz sampling Soft Mute Digital Attenuator (255 levels and 0.5dB step) Stereo Mode THD+N: -107dB DR, S/N: 120dB (Stereo mode: 123dB) I/F Format: 24/32bit MSB justified, 16/20/24/32bit LSB justified, I2S, DSD, TDM Master Clock: 30kHz ~ 32kHz: 1152fs 30kHz ~ 54kHz: 512fs or 768fs 30kHz ~ 108kHz: 256fs or 384fs 108kHz ~ 216kHz: 128fs or 192fs Power Supply: DVDD=AVDD=2.7 ∼ 3.6V, VDD1/2=4.75 ∼ 5.25V Digital Input Level: CMOS Package: 44pin LQFP MS1476-E-01 -1- 2013/01 http://www.Datasheet4U.com [AK4414] ■ Block Diagram DVDD DVSS PDN AVDD A...
