AD8203
the AD8203 system (Pin 3 and Pin 4 shorted). An example of
how to calculate the correct output voltage swing of the
AD8203, by taking all variables into account, follows:
Rev. B | Page 13 of 20
Amplifier A1 output saturation potential can go as low as
20 mV at its output.
A2 typical input bias current of 40 nA multiplied by the
100 kΩ preamplifier output resistor produces
40 nA × 100 kΩ = 4 mV at the A2 input
Total voltage at the A2 input equals the output saturation
voltage of A1 combined with the voltage error generated
by the input bias current
20 mV + 4 mV = 24 mV
The total error at the input of A2, 24 mV, multiplied by the
buffer gain generates a resulting error of 48 mV at the
output of the buffer. This is the AD8203 system output low
saturation potential.
The high output voltage range of the AD8203 is specified
as 4.8 V. Therefore, assuming a typical A2 input bias
current, the output voltage range for the AD8203 is 48 mV
to 4.8 V.
For an example of the effect of changes in A2 input bias current
vs. applied input potentials, see Figure 41. The change in bias
current causes a change in error voltage at the input of the
buffer amplifier. This results in a change in overall error
potential at the output of the buffer amplifier.
