PIN 0 = EPAD = AGND
NOTES
1. NC = NO CONNECT.
2. THE EXPOSED PADDLE MUST BE SOLDERED TO THE GROUND PLANE
FOR THE LFCSP PACKAGE. SOLDERING THE EXPOSED PADDLE TO
THE PCB INCREASES THE RELIABILITY OF THE SOLDER JOINTS,
MAXIMIZING THE THERMAL CAPABILITY OF THE PACKAGE.

AGND
Analog Ground (Exposed Paddle). The exposed paddle must be soldered to the ground
plane. Soldering the exposed paddle to the PCB increases the reliability of the solder joints,
maximizing the thermal capability of the package.
