An example of DC error calculations, using the
MAX4100/MAX4101 typical data and the typical operating
circuit with R
F
= R
G
= 200
(R
S
= 100
), gives:
Calculating total output-referred noise in a similar man-
ner yields:
With a 200MHz system bandwidth, this calculates to
133μV
RMS
(approximately 679μV
p-p
).
In both DC and noise calculations, errors are dominat-
ed by offset voltage and noise voltage (rather than by
input bias current or noise current).
Metal-film resistors with leads are manufactured using
a thin-film process, where resistive material is deposit-
ed in a spiral layer around a ceramic rod. Although the
materials used are noninductive, the spiral winding pre-
sents a small inductance (about 5nH) that may have an
adverse effect on high-frequency circuits.
