Suitable fan drive circuits are given in Figures 16a to 16f. When
using any of these circuits, the following points should be noted:
1. All of these circuits will provide an output range from zero
to almost 12 V, apart from Figure 17a which loses the base-
emitter voltage drop of Q1 due to the emitter-follower
configuration.
2. To amplify the 2.5 V range of the analog output up to 12 V,
the gain of these circuits needs to be around 4.8.
3. Care must be taken when choosing the op amp to ensure
that its input common-mode range and output voltage swing
are suitable.
4. The op amp may be powered from the 12 V rail alone or from
±
12 V. If it is powered from 12 V then the input common-
mode range should include ground to accommodate the
minimum output voltage of the DAC, and the output voltage
should swing below 0.6 V to ensure that the transistor can
be turned fully off.
5. If the op amp is powered from –12 V, precautions such as a
clamp diode to ground may be needed to prevent the base-
emitter junction of the output transistor being reverse-biased
in the unlikely event that the output of the op amp should
swing negative for any reason.
