and Gain vs. Gain-Setting Resistors
DC Errors and Noise
The MAX4158/MAX4159/MAX4258/MAX4259 output
offset voltage, VOUT (Figure 2) can be calculated with
the following equation:
VOUT = VOS x [1 + RF / RG] + IB x RS x [1 + RF / RG] +
IFB x RF
where:
VOS
= input offset voltage (in volts)
1 + RF / RG = amplifier closed-loop gain (dimensionless)
IB
= input bias current (in amps)
IFB
= feedback input bias current (in amps)
RG
= gain-setting resistor (in ohms)
RF
= feedback resistor (in ohms)
RS
= source resistor (in ohms)
The following equation represents output noise density:
where:
in = input noise current density (in A/√Hz)
en = input noise voltage density (in V/√Hz)
The MAX4158/MAX4159/MAX4258/MAX4259 have a
very low, 2nV/
√Hz noise voltage. The current noise at
the input (in) is 2pA/
√Hz, and the current noise at the
feedback input (in(FB)) is 22pA/
√Hz.
An example of DC-error calculations, using the
MAX4258 typical data and the typical operating circuit
with RF = RG = 510
(RF || RG = 255) and RS = 50,
gives:
VOUT = [1 x 10
-3 x (1 + 1)] + [2 x 10-6 x 50 x (1 + 1)] +
[2 x 10-6 x 510]
VOUT = 3.22mV
Calculating total output noise in a similar manner yields
the following:
With a 200MHz system bandwidth, this calculates to
168VRMS (approximately 1.01mVp-p, using the six-
sigma calculation).
Video Line Driver
The MAX4158/MAX4159/MAX4258/MAX4259 are opti-
mized to drive coaxial transmission lines when the
cable is terminated at both ends (Figure 3). Cable fre-
quency response may cause variations in the flatness
of the signal.
