APPLICATION CIRCUIT
Opposite figure shows a circuit for the
conversion of photo current to an equivalent
voltage. These voltage can be processed
e.g. with an ADC. By the selection of suitable
resistors the output voltage range can be
adjusted to the photo current value.
(for example the pin-programmable
transimpedance amplifier MTI04 with the
resistors 25k
Ω, 500kΩ
and 5M
Ω)
APPLICATION NOTE
It is recommended to use an IR-block filter > 720nm (MCS3BT) or a light source with low
infrared radiation for optimal operations of the colour sensor.
