DC and Noise Errors
Several major error sources must be considered in any
op amp. These apply equally to the MAX4188/
MAX4189/MAX4190. Offset-error terms are given by the
equation below. Voltage and current-noise errors are
root-square summed and are therefore computed sep-
arately. In Figure 4, the total output offset voltage is
determined by the following factors:
The input offset voltage (VOS) times the closed-loop
gain (1 = RF / RG).
The positive input bias current (IB+) times the
source resistor (RS) (usually 50 or 75), plus the
negative input bias current (IB-) times the parallel
combination of RG and RF. In current-feedback
amplifiers, the input bias currents at the IN+ and IN-
terminals do not track each other and may have
opposite polarity, so there is no benefit to matching
the resistance at both inputs.
The equation for the total DC error at the output is:
