The circuit shown can be used to
convert the current output to a
voltage. Resistor value, R1, and
Capacitor, C, are specified to
attain required gain and low-pass
filtering, which are application
specific. The gain is chosen to
attain maximum output swing
and not clamp the op-amp. V
should be set to 1.4 V
A 0.1 F bypass capacitor
(decoupling capacitor) is recom-
mended to be placed within 1 cm
of the encoder for optimal power
supply noise rejection. Outputs
are high impedance (typical 1
M ohm) and susceptible to EMI.
