PIN FUNCTIONS
Supply Pins
GND (Pins A1-2, A5-7, B2-4, B6, C2-3, C6, D1-3, D5-7,
D9-10, E5-6, E9-10, F1-2, F5-7, F9-10, G2-3, G6, H2-4,
H6, J1-2, J5-7): ADC Power Ground.
OGND (Pins A12, C9, G9, J12): Output Driver Ground.
OV
drivers. The specifi ed operating range is 0.5V to 3.6V. OV
is internally bypassed to OGND.
V
ply. The specifi ed operating range is 2.85V to 3.465V. The
voltage on this pin provides power for the amplifi er stage
and auxiliary DACs only and is internally bypassed to GND.
Note that LTM9002-LA does not have auxiliary DACs.
V
operating range is 2.7V to 3.6V. V
to GND.
Analog Inputs
CLKA (Pin A3): Channel A ADC Clock Input. The input
sample starts on the positive edge.
CLKB (Pin A4): Channel B ADC Clock Input. The input
sample starts on the positive edge.
DNC1 (Pin H5): Do Not Connect. These pins are used for
testing and should not be connected on the PCB. They
should be soldered to unconnected pads and should be
well isolated. The DNC pins connect to the signal path
prior to the ADC inputs; therefore, care should be taken
to keep other signals away from these sensitive nodes.
DNC1 connects near the channel A positive differential
analog input.
DNC2 (Pin G5): Do Not Connect. These pins are used for
testing and should not be connected on the PCB. They
should be soldered to unconnected pads and should be
well isolated. The DNC pins connect to the signal path
prior to the ADC inputs; therefore, care should be taken
to keep other signals away from these sensitive nodes.
DNC2 connects near the channel A negative differential
analog input.

DD
is internally bypassed

DNC3 (Pin C5): Do Not Connect. These pins are used for
testing and should not be connected on the PCB. They
should be soldered to unconnected pads and should be
well isolated. The DNC pins connect to the signal path
prior to the ADC inputs; therefore, care should be taken
to keep other signals away from these sensitive nodes.
DNC3 connects near the channel B positive differential
analog input.
DNC4 (Pin B5): Do Not Connect. These pins are used for
testing and should not be connected on the PCB. They
should be soldered to unconnected pads and should be
well isolated. The DNC pins connect to the signal path
prior to the ADC inputs; therefore, care should be taken
to keep other signals away from these sensitive nodes.
DNC4 connects near the channel B negative differential
analog input.
DNC5 (Pin G4): Do Not Connect. This pin is used for test-
ing and should not be connected on the PCB. It should
be soldered to an unconnected pad and should be well
isolated. This is a test point for the auxiliary DAC channel A
voltage output.
DNC6 (Pin C4): Do Not Connect. This pin is used for test-
ing and should not be connected on the PCB. It should
be soldered to an unconnected pad and should be well
isolated. This is a test point for the auxiliary DAC channel B
voltage output.
