4.6 Initialization time
The TSV73x series of devices use a proprietary trimming topology that is initiated at each
device power-up and allows excellent V
io
performance to be achieved. The initialization time
is defined as the delay after power-up which guarantees operation within specified
performances. During this period, the current consumption (I
CC
) and the input offset voltage
(V
io
) can be different to the typical ones.
Figure 22. Initialization phase
The initialization time is V
CC
and temperature dependent. Table 6 sums up the
measurement results for different supply voltages and for temperatures varying from -40 °C
to 125 °C.
4.7 PCB layouts
For correct operation, it is advised to add a 10 nF decoupling capacitors as close as
possible to the power supply pins.
