THE EXPOSED PADDLE MUST BE SOLDERED TO THE PCB ANALOG GROUND TO ENSURE PROPER FUNCTIONALITY AND HEAT DISSIPATION, NOISE, AND MECHANICAL STRENGTH BENEFITS. Figure 6. Pin Configuration Table 8. Pin Function Descriptions Pin No. Mnemonic Type Description ADC Power Pins 1, 2, 35, 36, 37, 40, 42, 44, 45, 48 AVDD Supply Analog Power Supply (1.8 V Nominal). 8, 27 DRVDD Supply Digital Output Driver Supply (1.8 V Nominal). 7, 28 DRGND Ground Digital Output Ground. 0 AGND Ground Analog Ground. Pin 0 is the exposed thermal pad on the bottom of the package. This is the only ground connection, and it must be soldered to the PCB analog ground to ensure proper functionality and heat dissipation, noise, and mechanical strength benefits.
