8.6.3 Full manual mode: manual selection of bandwidth and slew rate
By setting both BW[4:0] and SLEW[4:0] to 00000, the automatic bandwidth and the slew
rate adjustment of the TZA3054A are completely switched off and the values for the
bandwidth and slew rate can be controlled manually.
The bandwidth of the input stage and the slew rate of the output stage can be controlled
with the bits BWOCT[2:0] in I
I
Table 15
In this mode the user gets 6 different limiting amplifiers, all optimized for their respective
bandwidth range. The bandwidth spans from 1 kHz to the highest frequency of the chosen
octave.
In the event that the DC cancellation loop is disabled as well, the lowest frequency is
determined by the input coupling capacitor in combination with the input impedance. This
enable burst mode operation.
