APPLICATIONS INFORMATION
LT6402-12
Large Output Voltage Swings
The LT6402-12 has been designed to provide the 3.2V
P
low-noise ADCs. This additional output swing improves
system SNR by up to 4dB.
Input Bias Voltage and Bias Current
The input pins of the LT6402-12 are internally biased to
the voltage applied to the V
resistors are needed, even for AC-coupled operation. The
input bias current is determined by the voltage difference
between the input common mode voltage and the V
pin (which sets the output common mode voltage). For
example, if the inputs are tied to 2.5V with the V
at 2.2V, then a total input bias current of 2mA will fl ow
into the LT6402-12’s +INA and +INB pins. Furthermore,

an additional input bias current totaling 2mA will fl ow into

Application (Demo) Boards
The DC954A Demo Board has been created for stand-alone
evaluation of the LT6402-12 with either single-ended or
differential input and output signals. As shown, it accepts
a single-ended input and produces a single-ended output
so that the LT6402-12 can be evaluated using standard
laboratory test equipment. For more information on this
Demo Board, please refer to the layout and schematic
diagrams found later in this data sheet.
There are also additional demo boards available that
combine the LT6402-12 with a variety of different Linear
Technology ADCs. Please contact the factory for more
information on these demo boards.
