AK4386VT-E2

The AK4386VT-E2 is a 24bit low voltage and low power stereo DAC. The AK4386VT-E2 uses the Advanced Multi-Bit DS architecture which achieves DR=100dB at 3V operation. The AK4386VT-E2 integrates SCF and CTF filters increa sing performance for systems with excessive clock jitter. The AK4386VT-E2 is fit for the portable audio system like MP3 and the home audio systems like STB and TV, etc as low power and small package. The AK4386VT-E2 is provid ed in a space saving 16pin TSSOP package.

The AK4386VT-E2 has the following features:(1)sampling rate is from 8kHz to 96kHz;(2)24-bit 8 times FIR digital filt er;(3)SCF with high tolerance to clock jitter;(4)single-ended output buffer;(5)digital de-emphasis for 44.1kHz samp ling;(6)I/F format: 24-Bit MSB justified, 16/24-Bit LSB justified, I2S Compatible;(7):CMOS input level;(8)THD+N is -86dB;(9)power supply is from 2.2V to 3.6V.

It has some maxium ratings and switching characteristics.maxium ratings:(1)power pupply is -0.3V min and 4.6 V max;(2):input current, any pin except supplies(IIN)is±10 mA max;(3):digital input voltage (VIND) is -0.3 V min, VDD+ 0.3 V max;(4)ambient temperature (Powered applied)is -40°C min and 85 °C max;(5)storage temperature is -65°C min and 150 °C max.switching characteristics:(1):master clock frequency:half speed mode  is 4.096 MHz min and 36.864 MHz max,normal speed mode (256/384/512/768fs) is 2.048 MHz min and 36.864 MHz max,double speed mod e (128/192/256/384fs) is 6.144 MHz min and 36.864 MHz max;(2)lack frequency:half speed mode (DFS1-0 = "10") is 8 kHz min and 24 kHz max, normal speed mode (DFS1-0 = "00") is 8 kHz min and 48 kHz max,double speed mod e (DFS1-0 = "01") is 48 kHz min and 96 kHz max;(3):audio interface timing:half speed mode is 1/128fs ns min, nor mal speed mode is 1/128fs ns min,double speed mode is 1/64fs ns min.etc
