Single-ended input configuration
The single-ended
TSA1005-40 requires particular biasing and driv-
ing. The structure being fully differential, care has
to be taken in order to properly bias the inputs in
single-ended mode. Figure 6 summarizes the link
from the differential configuration to the sin-
gle-ended one; a wrong configuration is also pre-
sented.
- With differential driving, both inputs are centered
around the INCM voltage.
input configuration
of the
- The transition to single-ended configuration
implies to connect the unused input (VINB for
instance) to the DC component of the single input
(VIN) and also to the input common mode in order
to be well balanced. The mid-code is achieved at
the crossing between VIN and VINB, therefore
inputs are conveniently biased.
- Unlikely other structures of converters in which
the unused input can be grounded; in our case it
will end with unbalanced inputs and saturation of
the internal amplifiers leading to a non respect of
the output codes.

Input dynamic range for the various configurations
The applications requiring single-ended inputs
can be configured like reported on Figure 7 for an
AC-coupled input or on Figure 8 for a DC-coupled
input.
In the case of AC-coupled analog input, the
analog inputs VIN and VINB are biased to the
same voltage that is the common mode voltage of
the circuit (INCM). The INCM and reference
voltages may remain at their internal level but can
also be fixed externally.
In the case of DC-coupled analog input with 1V
DC signal, the DC component of the analog input
