Ground wire instructions
There is no connection between AGND and GND in OTG13S that asked for connecting on the user board.
If +5V power supply ground wire and analog ground wire are in the power supply terminal, the connection point
will be connected with power supply, or should near to the OTG13S pins. GND connects with ground wire of
metal outer covering to keep the resistance of ground wire lower for a good effect. The position nearing the
OTG13S pins is preferable for a better effect.
‹
Power supply instructions
When need not to support USB mobile hard disk, +5V power supply can use various linear voltage
regulators such as 7805, and the current should exceed 300mA.
When need to support USB mobile hard disk, it is preferable that +5V power supply adopts switch power
supply such as LM2567, current should exceed 800mA, the voltage adjusted is about +5.3V, and it can make sure
that hard disk has enough current and voltage. At UPW pin, adding a switch connecting 470R resistance and
S8550 in parallel can make the power supply current of USB mobile hard disk higher than 700mA.
the power supply voltage range of USB HOST interface is +5V/±0.5V.

Audio Frequency Instructions
± Power supply is the best choice for the sake of a good effect ,if the power supply of the complete
machine is ±power supply. Or single power supply can be adopted, and the plus input of operational amplifier
connects with 1/2 power supply, as the following diagram 5. If there is no requirement for the sound, operational
amplifier is not required and resistor and capacitor filter can be directly applied, as the following diagram 6, but
signal output range and high frequency effect may be not good.

OTG13S upgrading file instructions
OTG13S program employs OTG13.AR5 as upgrading file, this file can be sent to user after the whole
machine leaves factory. Inserting U disk can automatically upgrade program after copying OTG13S.AR5 file in
the root directory of U disk, and OTG BIOS can automatically identify new file. If the file in the U disk is
identical with OTG13S file, OTG13S program will not be upgraded.
OTG13S.AR5 can’t exceed 32K bytes, and upgrading can be finished within several seconds.
The electricity supply can’t be cut off bang in the middle of the upgrading.
