10. Limiting values
[1]
VP = VDDP1 VSSP1 = VDDP2 VSSP2.
[2]
Measured with respect to pin INREF; Vx < VDD + 0.3 V.
[3]
Measured with respect to pin VSSD(HW); Vx < VDD + 0.3 V.
[4]
Measured with respect to pin CGND; Vx < VDD + 0.3 V.
[5]
VSS = VSSP1 = VSSP2; VDD = VDDP1 = VDDP2.
[6]
Current limiting concept.
11. Thermal characteristics
[1]
Measured in a JEDEC high K-factor test board (standard EIA/JESD 51-7) in free air with natural convection.
[2]
Strongly depends on where you measure on the package.
Table 8.
Limiting values
In accordance with the Absolute Maximum Rating System (IEC 60134).
