Layout precautions
To use the TSH8X circuits in the best manner at high frequencies, some precautions have to
be taken for power supplies:
In high-speed circuit applications, the implementation of a proper ground plane on both
sides of the PCB is mandatory to ensure low inductance and low resistance common
return.
Power supply bypass capacitors (4.7F and ceramic 100pF) should be placed as close
as possible to the IC pins in order to improve high frequency bypassing and reduce
harmonic distortion. The power supply capacitors must be incorporated for both the
negative and the positive pins.
All inputs and outputs must be properly terminated with output resistors; thus, the
amplifier load is resistive only and the stability of the amplifier will be improved.
All leads must be wide and as short as possible especially for op-amp inputs and
outputs in order to decrease parasitic capacitance and inductance.
In lower gain applications, use a low feedback resistance (under 1k
Ω) to reduce the
time constant with parasitic capacitance.
Choose component sizes as small as possible (SMD).
On the output, the load capacitance must be negligible to maintain good stability. You
can put a serial resistance as close as possible to the output pin to minimize the effect
of the load capacitance.
