How to specify and use analog switches
An analog switch is an IC that can be used to control connections to analog and digital signals. These switches provide bidirectional connections when ‘on’ and high impedance paths when ‘off.’ There’s a wide range of analog switches for special functions. In some instances, they are used in place of mechanical switches. In other embodiments, […]

How does skin color impact biosensors?
To determine blood oxygen (arterial blood oxygen saturation (SpO2)) and pulse rate, many biosensors use the reflectance of red and infrared (and sometimes green) light. Based on photoplethysmography (PPG), an optical technique that measures blood volume variations, dual-wavelength PPG pulse oximeters noninvasively measure/calculate the arterial oxygen saturation (SpO2). An oximeter transmits radiation at a known […]
Digital isolators comply with VDE and UL safety standards.
STMicroelectronics has extended its family of dual-channel high-speed digital isolators, enhancing flexibility for designers to optimize their board layout. The new STISO620 contains two channels of the same directionality, having all digital inputs on one side of the isolation barrier and all digital outputs on the other side. . It joins ST’s digital isolator lineup alongside the STISO621 and […]
