The MLX75303 IC, Melexis SensorEyeC series are CMOS integrated optical sensors including photodiode, transimpedance amplifier and output transistor on one chip. The sensor is designed for high-volume applications like day/night detection, paper feed detection in copiers and printers, LCD backlight dimming, LED light control, infrared range detection and safety screens.
The MLX75303 IC 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.
The SensorEyeC series are perfect replacements for discrete photodiodes, phototransistors and light dependent resistors (LDR). SensorEyeC devices are integrated light sensors with photodiode, a transimpedance amplifier and output transistor in one chip to simplify application design, enhance quality and minimize use of external components.
