General Description

The Melexis SensorEyeC series are CMOS integrated optical sensor ICs including photodiode,

transimpedance amplifier and output transistor on one chip.

The MLX75303 features a Schmitt Trigger output and is designed for high-volume automotive and non-

automotive applications.

The MLX75303 block diagram is shown in Section 1 and contains following blocks: a transimpedance

amplifier to convert and amplify the photocurrent of the photodiode, a voltage reference, a Schmitt trigger

and an open drain output stage.
