NOTES
1. FOR OPTIMUM PERFORMANCE, EXTERNAL COMPONENTS
CONNECTED TO THE COMP, RSET, VREF AND DAC OUTPUT
PINS SHOULD BE LOCATED CLOSE TO AND ON THE SAME
SIDE OF THE PCB AS THE ADV7342/ADV7343.
2. THE I2C DEVICE ADDRESS IS CONFIGURABLE USING THE
ALSB PIN:
ALSB = 0, I2C DEVICE ADDRESS = 0xD4 OR 0x54
ALSB = 1, I2C DEVICE ADDRESS = 0xD6 OR 0x56
ADI RECOMMENDS TO TIE ALSB TO VDD_IO. PLEASE
REFER TO POWER SUPPLY SEQUENCING SECTION FOR
MORE INFORMATION ON THIS.
3. THE RESISTORS CONNECTED TO THE RSET PINS SHOULD
HAVE A 1% TOLERANCE.
