... ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although the AD1886A features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality ...

... Note: Writing any value to this register performs a register reset, which causes all registers to revert to their default values (except 74h, which forces the serial configuration). Reading this register returns the ID code of the part and a code for the type of 3D Stereo Enhancement. ID[9:0] Identify Capability. The ID decodes the capabilities of AD1886A based on the following: Bit = 1 ID0 ID1 ...

... The AD1886A features a Jack Sense pin (JS) that can be used with the HP_OUT or LINE_OUT jacks to automatically mute the other audio outputs. When the Jack Sense pin is connected to one of the output jacks, the AD1886A can sense whether an audio plug has been inserted into the jack and automatically mute the LINE_OUT or MONO_OUT or both outputs. ...

... MICROPHONE CONNECTIONS The AD1886A contains an internal microphone preamp with 20 dB gain; in most cases a direct microphone connection as shown in Figure 16 is adequate. If the microphone level is too low, an external preamp can be added as shown in Figure 17. In either case the microphone bias can be derived from the codec’s internal reference (V V signal can also provide the midpoint bias for the amplifier ...

Page 27

... MIC INPUT LINE OUTPUT CONNECTIONS The AD1886A Codec provides stereo LINE_OUT signals at a standard 1 V rms level. These signals must be ac-coupled before they can be connected to an external load. After the ac-coupling, a minimal resistive load is recommended to keep the capacitors properly biased and reduce clicks and pops when plugging stereo equipment into the output jack. The capacitor values should be selected to provide a desired frequency response, taking into account the nominal impedance of the external load. To meet the PC99 specifica- tion for PCs, testing must be performed with a 10 kΩ ...
