Table 5-1 Pin Functions
PIN TYPE DESCRIPTION
NAME NO.
A0 4 Input Gain setting pin 0
A1 5 Input Gain setting pin 1
A2 1 Input Gain setting pin 2
DGND 16 Power Ground reference for digital logic and gain setting pins
FDA_IN– 9 Input Connection to output driver summing node
FDA_IN+ 12 Input Connection to output driver summing node
IN– 3 Input Negative (inverting) input
IN+ 2 Input Positive (noninverting) input
LVDD 7 Power Output driver positive supply. Connect this pin to the positive supply of the ADC to protect from overdriving.
LVSS 14 Power Output driver negative supply. Connect this pin to the negative supply of the ADC to protect from overdriving.
NC 8 — Do not connect
OUT– 11 Output Output (inverting)
OUT+ 10 Output Output (noninverting)
VOCM 13 Input output common mode control pin
VS+ 6 Power Input stage positive supply
VS– 15 Power Input stage negative supply
Thermal Pad Thermal pad — Solder the thermal pad to the printed-circuit board (PCB). Connect the thermal pad to a plane or large copper pour that is either floating or electrically connected to VS–. Make this connection even for applications that have low power dissipation.
