Maxim Integrated Products Inc. has developed a digital ambient-light and infrared proximity sensor that detects light like a human eye.
Designed using the company's proprietary BiCMOS technology, the MAX44000 integrates three optical sensors, two A/D converters, and digital functionality into a tiny 2mm x 2mm x 0.6mm package.
The MAX44000 consumes low power: 5ľA when the ambient sensor is enabled, and 7ľA when both the proximity sensor and ambient light sensor are activated. This low-power usage extends battery life. The MAX44000 is aimed at touch-screen applications, including smartphones, portable devices, industrial sensors, and presence detection.
