Maxim Integrated Products Inc. (Sunnyvale, CA) has introduced the MAX44000, a digital ambient-light and infrared proximity sensor that detects light like a human eye. Designed using the company’s proprietary BiCMOS technology, this IC integrates three optical sensors, two ADCs, and digital functionality into a tiny 2mm x 2mm x 0.6mm package. This integration saves valuable board space while delivering optical fusion and unparalleled light-sensing performance. The MAX44000 also consumes very low power: only 5µA when the ambient sensor is enabled, and only 7µA when both the proximity sensor and ambient light sensor are activated. This low-power usage significantly extends an application’s battery life. The MAX44000 is ideal for touch-screen applications, including smartphones, portable devices, industrial sensors, and presence detection.
