Analog Input. This input must be free of data transfer. noise with respect to GND.
VCC (Pin 8):
Positive Supply. This supply must be kept
GND (Pin 4):
Analog Ground. GND should be tied directly free of noise and ripple by bypassing directly to the to an analog ground plane. analog ground plane. For LTC1199/LTC1199L, VREF is tied internally to this pin.
VREF (Pin 5):
LTC1197/LTC1197L Reference Input. The reference input defines the span of the A/D converter and must be kept free of noise with respect to GND.
