Depending on the method of lead termination at the edge of the package, pull back (L1) may be present.
L minus L1 to be equal to, or greater than 0.3mm
The underside of the package has an exposed metal pad which should ideally be soldered to the pcb to enhance the thermal
conductivity and mechanical strength of the package fixing. Where advised, an electrical connection to this metal pad may also
be required
Notes:
1. In this device, the underside of the Q3 package should be electrically connected to the analogue ground. The circuit
board should be designed so that no unwanted short circuits can occur.
2. As package dimensions may change after publication of this datasheet, it is recommended that you check for the latest
Packaging Information from the Datasheets page of the CML website: [www.cmlmicro.com].
