Interface Circuit
The circuit shown can be used to
convert the current to voltage
output. 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 clamping
the op-amp. V
to 1.4 V
capacitor is recommended to be
placed within 1 cm of the
encoder for optional power
supply noise rejection. Output
are high impedance (typical 1M
Ohm) and susceptible to EMI.
