this bias current (30
μ
A max.) as the 1% of the cur-
rent through the resistance divider to keep a sta-
ble mid-supply, two resistances of 2.2k
can be
used in the case of a 12V power supply and two
resistances of 820
can be used in the case of a
5V power supply.
The input provides a high pass filter with a break
frequency below 10Hz which is necessary to re-
move the original 0 volt DC component of the input
signal, and to fix it at +V
CC
/2.
CHANNEL SEPARATION - CROSSTALK
The following figure shows the crosstalk from an
amplifier to a second amplifier. This phenomenon,
accentuated at high frequencies, is unavoidable
and intrinsic to the circuit.
Nevertheless, the PCB layout also has an effect
on the crosstalk level. Capacitive coupling be-
tween signal wires, distance between critical sig-
nal nodes and power supply bypassing are the
most significant factors.

INVERTING AMPLIFIER BIASING
In this case a resistance R is necessary to achieve
good input biasing, see Figure 66.
This resistance is calculated by assuming the neg-
ative and positive input bias current. The aim is to
compensate for the offset bias current which could
affect the input offset voltage and the output DC
component. Assuming Ib-, Ib+, R

and a zero
volt output, the resistance R comes: R = R
