AD1882A

The AD1882A audio codec and SoundMAX software provides superior HD audio quality that exceeds Vista Premium performance.The AD1882A has six DACs and four ADCs, two stereo headphone ports, C/LFE swapping, digital and analog PCBeep,and S/PDIF output.Here you can get some information about the features.First is the six 192 kHz,95 dB DACs which have all independent sample rates,8 kHz through 192 kHz,16-,20-, and 24-bit PCM resolution,and selectable stereo mixer on outputs.Then is the four 192 kHz, 90 dB ADCs which have simultaneous record of up to 2 stereo channels,all independent sample rates, 8 kHz through 192 kHz and 16-, 20-, and 24-bit resolution.Next is the S/PDIF output that supports all sample rates 44.1 kHz through 192 kHz 16-, 20-, and 24-bit data widths; PCM and AC3 formats Digital PCM gain control.The fourth one is the stereo digital microphone which have two 192 kHz digital microphone channels,supports 1 or 2 microphones on 1 pin,have selectable bit clock rates of 1.5 MHz, 2.0 MHz, and 3.0 MHz,have all sample rates, 8 kHz through 192 kHz and 16-, 20-, and 24-bit resolution.Besides,it has 2 general-purpose digital I/O (GPIO) pins.The fifth one is the 3.3 V analog and digital supply voltage.The sixth one is the 1.5 V and 3.3 V HD Audio link signaling.The last one is its very low power consumption in D3 state.
What comes next is about the absolute maximum ratings of AD1882A.The Digital (DV_DD) is from -0.30 V to +3.65 V.The Digital I/O (DV_IO) is from -0.30 V to +3.65 V.The Digital GPIO (DV_GPIO) is from -0.30 V to +3.65 V.The Analog (AV_DD) is from -0.30 V to +3.65 V.The Input Current (Except Supply Pins) is ±10.0 mA.The Analog Input Voltage (Signal Pins) is from -0.30 V to AV_DD + 0.3 V.The Digital Input Voltage (Signal Pins) is from -0.30 V to DV_IO + 0.3 V.The Ambient Temperature (Operating) is from 0 to +70.The Storage Temperature is from -65 to +150.
