First Components offers Energy Saver: Ambient Light Sensor CM3202 with Analog Output

(PresseBox) (München, ) First Components introduces an ALS (Ambient Light Sensor) with analog output for light-sensing control applications from Capella Microsystems Inc. a specialist for visible light sensors and UV-sensors. The CM3202 is designed with an analog CMOS process and consists of a photodiode, an amplifier and a control-logic integrated in one chip. The spectral sensitivity is similar to the human eye with a dominant wavelength of 550 nanometers. The range of sensitivity starts as low as 0.625 lux up to a maximum of 3,000 lux.

The CM3202 offers an excellent temperature compensation, robust refresh rate setting without any external RC low pass filter. A software shut down mode is provided which reduces power consumption to less than 1 microampere. The ambient light sensor has a 9 bit resolution. The operating voltage ranges from 2.7V to 6.0 Volt. The 6 pin OPLGA package size is 2.35x1.8x1mm. Additionally a CMP package with 10 pins is available in 4x3mm size. The photo input can be from top or from bottom of the IC package in two versions. The operating temperature ranges from -40°C to +85°C, which is excellent for industrial applications.

Capellas ambient light sensors can be used in numerous applications like notebooks, flat-screen TVs, mobile phones, smart phones, personal digital assistants, lighting and automotive designs. Capellas light and UV-sensors are leadfree and ROHS conform. Light sensors are energy-savers, and help keeping energy cost down as well as extending the lifetime of electronic products.
