These ampliers provide either an inverting or non-inverting
transfer gain based upon the type of input and output ampli-
er. Table 2 shows the various congurations along with the
specic transfer gain equations. The offset column refers to the
calculation of the output offset or Vref2 necessary to provide a
zero voltage output for a zero voltage input. The non-inverting
input amplier requires the use of a bipolar supply, while the
inverting input stage can be implemented with single supply
operational ampliers that permit operation close to ground.
For best results, place a buffer transistor between the LED and
output of the operational amplier when a CMOS opamp is
used or the LED IFq drive is targeted to operate beyond 15
mA. Finally the bandwidth is inuenced by the magnitude of
the closed loop gain of the input and output ampliers. Best
bandwidths result when the amplier gain is designed for unity.
