Optical sensor detects light like a human eye

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: 5µA when the ambient sensor is enabled, and 7µA 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.

Key highlights:

• Tiny, 2mm x 2mm x 0.6mm UTDFN-Opto Package
• VDD = 1.7V to 3.6V
• Low-Power Operation
  • 5µA in Ambient Mode
  • 7µA in Proximity Mode
  • 70µA in Ambient Plus Proximity Mode, Including 100mA LED Current
• Excellent Light-Source Matching
  • Programmable Green and IR Channel Gains
• Integrated Single-Pulse IR LED Driver
  • 10mA to 110mA Programmable Range
  • Internal Ambient Cancellation
• -40°C to +105°C Temperature Range
