June 30, 2012 - Optical solutions provider Emmis Osram announces the launch of its first purely integrated circuit vitals sensor family, the AS705x. Emmis Osram's first generation biosignal conversion device offers manufacturers great flexibility with a highly customizable optical front end combined with an energy efficient design and small form factor, ideal for applications where board space is limited, such as listening devices, smart watches or smart patches.
The AS7050 is the first biosignal sensor in a new family of products from Emmis Osram that allows end users to capture biological signals such as HeartRate Monitor and Galvanic Skin Resistance. With two ADC channels and an embedded ECG low-noise analog front-end, the AS7050 enables simultaneous photoplethysmography and electrocardiogram (ECG) measurements. Customers who need smaller optics and do not require ECG can choose the AS7056 or AS7057 series.
The AS7056 and AS7057 are the smallest AFEs on the market today for vital signs monitoring with a chip size of approximately 1.7 mm x 1.7 mm," said Dr. Markus Arzberger, Head of Business Unit Vital Signs Monitoring Applications at Emmis Osram. signs. Both products allow customers to combine advanced analog-to-digital conversion processes to develop extremely small, highly customized optical front ends."
The AS7050 provides up to eight LED driver outputs, samples up to six photodiode inputs, and supports external electrodes. the AS7056 and AS7057 support up to three photodiodes as well as three emitters, with one of the AS7056 emitters being a VCSEL driver. This provides a high degree of flexibility for various emitter and photodiode setups in different applications.
