Precautions when operating on an asymmetrical supply
The TSH7X can be used with either a dual or a single supply. If a single supply is used, the
inputs are biased to the mid-supply voltage (+V
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 so as not to
introduce an offset mismatch at the amplifier inputs.
Figure 49. Schematic of asymmetrical (single) supply
R1 = 10K Ω is a typical and convenient value. C1, C2, C3 are bypass capacitors that filter
perturbations on V
and C2 = C3 = 100uF.
R2, R3 are such that the current through them must be greater than 100 times the bias
current. Therefore, we set R2 = R3 = 4.7K Ω .
