Table 1. Gives the value of R5 given the production K3 bin.
The last step in the design is selecting the LED current
limiting resistor (R4). The output of the operational amplifier
is targeted to be 50 % of the V
quiescent current of 12 mA the typical LED (V
Given this and the operational output voltage, R4 can be
calculated.
The circuit was constructed with an LM201 differential
operational amplifier using the resistors selected. The
amplifier was compensated with a 100 pF capacitor
connected between pins 1 and 8.
The DC transfer characteristics are shown in figure 17. The
amplifier was designed to have a gain of 0.6 and was
measured to be 0.6036. Greater accuracy can be achieved
by adding a balancing circuit, and potentiometer in the input
divider, or at R5. The circuit shows exceptionally good gain
linearity with an RMS error of only 0.0133 % over the input
voltage range of 4 V to 6 V in a servo mode; see figure 15.
