SHOULD BE LOCATED
CLOSE TO THE EXT_LF
PIN AND ON THE
SAME SIDE OF THE PCB
AS THE ADV7390/ADV7391/
ADV7392/ADV7393.
NOTES
1. FOR OPTIMUM PERFORMANCE, EXTERNAL COMPONENTS CONNECTED
TO THE COMP, R
SET
AND DAC OUTPUT PINS SHOULD BE LOCATED
CLOSE TO, AND ON THE SAME SIDE OF THE PCB AS, THE
ADV7390/ADV7391/ADV7392/ADV7393.
2. THE I

C DEVICE ADDRESS IS CONFIGURABLE USING THE ALSB PIN:
ALSB = 0, I

C DEVICE ADDRESS = 0xD4 (ADV7390/ADV7392) OR
0x54 (ADV7391/ADV7393)
ALSB = 1, I
2
C DEVICE ADDRESS = 0xD6 (ADV7390/ADV7392) OR
0x56 (ADV7391/ADV7393)
3. THE RESISTOR CONNECTED TO THE R
SET
PIN SHOULD HAVE A 1%
TOLERANCE.
4. THE RECOMMENDED MODE OF OPERATION FOR THE DACs IS FULL-
DRIVE (R
SET
= 510Ω, R
