Figure 6. Peak-to-Peak Noise (0.1 Hz to 10 Hz) vs. Source
Resistance (Includes Resistor Noise)
Figure 6 shows peak-to-peak noise versus source resistance over
the 0.1 Hz to 10 Hz range. Once again, at low values of RS, the
voltage noise of the OP471 is the major contributor to peak-to-peak
noise. Current noise becomes the major contributor as RS increases.
The crossover point between the OP471 and the OP400 for
peak-to-peak noise is at RS = 17
W.
The OP470 is a lower noise version of the OP471, with a typical
noise voltage density of 3.2 nV/
÷Hz @ 1 kHz. The OP470 offers
lower offset voltage and higher gain than the OP471, but is a slower
speed device, with a slew rate of 2 V/
ms compared to a slew rate
of 8 V/
ms for the OP471.

Comments
Strain gauge
< 500
W
Typically used in
low-frequency applications.
Magnetic
< 1,500
W
Low IB very important to reduce
tapehead
self-magnetization problems
when direct coupling is used.
OP471 IB can be neglected.
Magnetic
< 1,500
W
Similar need for low IB in direct
phonograph
coupled applications. OP471
cartridges
will not introduce any
self -magnetization problem.
Linear variable
< 1,500
W
Used in rugged servo-feedback
differential
applications. Bandwidth of
transformer
interest is 400 Hz to 5 kHz.
