SAF7167AHW
YUV-to-RGB digital-to-analog converter
8. Limiting values
[1] Class 2 according to EIA/JESD22-114-B.
[2] Class B according to EIA/JESD22-115-A.
9. Thermal characteristics
[1] The overall R
th(j-a)
value can vary depending on the board layout. To minimize the effective R
th(j-a)
all power
and ground pins must be connected to the power and ground layers directly. An ample copper area direct
under the SAF7167AHW with a number of through-hole plating, which connect to the ground layer
(four-layer board: second layer), can also reduce the effective R
th(j-a)
. Please do not use any solder-stop
varnish under the chip. In addition the usage of soldering glue with a high thermal conductance after curing
is recommended.
10. Static characteristics
Table 12: Limiting values
In accordance with the Absolute Maximum Rating System (IEC 60134). All ground pins and all
supply pins connected together.
