PIN CONFIGURATION
QFN24-4x4 (4 mm x 4 mm)
The Thermal Pad on the underside of the package should be appropriately connected to GND for better heat
dissipation (ground plane). GNDA should also be directly connected to neutral point GND. Ground loops should
be avoided.
Only the Pin 1 mark on the front or reverse is determinative for package orientation (
subject to change).
