The front end of the multi -mode sensor is an ideal choice for wearable mights

     Analog Devices stores the front end of the ADPD4200 multimione sensor. This device is a complete light sensor front end, which stimulates up to four LEDs, and measures the return signal of up to four independent current input. The device has 12 time slots, and each sampling cycle allows 12 separate measurements. The sensor integrates flexible LED signals and synchronous detection control circuits. The front end of the sensor uses 1.8V analog nucleus and 1.8V or 3.3V compatible digital input/output.

     The device provides dual -channel treatment, samples at the same time, digital filtering on the film, 400mA total LED peak driving current, 512 byte FIFO size. The front end of the sensor is very suitable for a variety of applications, including wearable health and fitness monitors, industrial monitoring and family patient monitoring equipment.
