Highly integrated optical sensors measure RGB, ambient light, proximity motion, infrared, and temperature
July 11, 2012 // Paul Buckley
Maxim Integrated Products has introduced four, new digital optical sensors that advance analog integration with sensor fusion.
The MAX44004/05/06/08 measure red/green/blue (RGB) light levels, ambient visible light (ALS), proximity to the sensor, ambient infrared (IR) levels, and temperature. As many as seven sensors are integrated into one compact optical package. The sensors provide robust and repeatable measurements and the MAX44005/MAX44006/MAX44008 all consume what is claimed to be an industry-low 20 µA each.
The high integration reduces system cost, eliminates several external components, and greatly simplifies design. These optical sensors can be used in a wide variety of applications such as smartphones, tablets, portable consumer devices, displays, digital light management, security systems, and medical devices.
The MAX44004 is a low-power ALS that consumes 5 µA. The MAX44006/MAX44008 integrate RGB color sensors plus an ALS (clear), an ambient IR, and temperature sensors while the MAX44005 includes an RGB color sensor plus an ALS (clear), ambient IR, IR proximity, and temperature sensors.
Availability and Pricing
The MAX44005/MAX44006/MAX44008 are guaranteed over the -40 to +85°C temperature range. The MAX44004 is guaranteed over the -40°C to +105°C temperature range. All sensors are available in a 2 mm x 2 mm x 0.6 mm optical package. Pricing starts at $1.20 (1000-up, FOB USA).
