Precautions on asymmetrical supply
operation:
The TSH8X can be used either with a dual or a
single supply. If a single supply is used, the inputs
are biased to the mid-supply voltage (+Vcc/2).
This bias network must be carefully designed, in
order to reject any noise present on the supply rail.
As the bias current is 15uA, you must carefully
choose the resistance R1 not to introduce an off-
set mismatch at the amplifier inputs.
R1=10k
will be convenient. C1, C2, C3 are by-
pass capacitors from perturbation on Vcc as well
as for the input and output signals. We choose
C1=100nF and C2=C3=100uF.
R2, R3 are such that the current through them
must be superior to 100 times the bias current. So,
we take R2=R3=4.7k
.
Cin, as Cout are chosen to filter the DC signal by
the low pass filters (R1,Cin) and (Rout, Cout). By
taking R1=10k
, RL=150
,
and Cin=2uF,
Cout=220uF we provide a cutoff frequency below
10Hz.
Use of the TSH8X in gain=-1 configuration:
Some precautions have to be added, specially for
low power supply application.
A feedback capacitance Cf should be added for
better stability. The table summarizes the impact
of the capacitance Cf on the phase margin of the
circuit.
