U U U PIN FUNCTIONS DIN (Pin 1):
Digital Input. The A/D configuration word is
GND (Pin 5):
Ground Pin. GND should be tied directly to shifted into this input. an analog ground plane.
DOUT (Pin 2):
Digital Output. The A/D result is shifted out
+VIN (Pin 6):
Positive Analog Differential Input. The pin of this output. can be used as a single-ended input by grounding – VIN.
CLK (Pin 3):
Shift Clock. This clock synchronizes the serial
– VIN (Pin 7):
Negative Analog Differential Input. The input data. must be free from noise.
CS (Pin 4):
Chip Select Input. A logic low on this input
VCC (Pin8):
Positive Supply. This supply must be kept free enables the LTC1392. from noise and ripple by bypassing directly to the ground plane.
