Power consumption
The internal architecture of the TSA1002 enables
to optimize the power consumption according to
the sampling frequency of the application. For this
purpose, a resistor is placed between IPOL and
the analog Ground pins. The figure 10 sums up
the relevant data.
The TSA1002 will combine highest performances
and lowest consumption at 50Msps when Rpol is
in the range of 12k
to 20k.
At lower sampling frequency, this value of resistor
may be changed and the consumption will
decrease as well.

Linearity, distortion performance towards
Clock Duty Cycle variation
The TSA1002 has an outstanding behaviour
towards clock duty cycle variation and it may be
also reinforced with adjustment of analog current
consumption.
Linearity vs. Duty cycle
Fs=50MSPS; consumption optimized; Fin=1MHz
Distortion vs. Duty cycle
Fs=50MSPS; consumption optimized; Fin=1MHz
Linearity vs. Duty cycle
Fs=50MSPS; Icca=20mA; Fin=10MHz
Distortion vs. Duty cycle
Fs=50MSPS; Icca=20mA; Fin=10MHz
