TI chip combines body analysis in weighing scales

Electronics News Updates / By

Description The AFE4300 is a low-cost analog front-end incorporating two separate signal chains: one chain for weight-scale (WS) measurement and the other for body composition measurement (BCM) analysis. A 16-bit, 860-SPS analog-to-digital converter (ADC) is multiplexed between both chains. The weight measurement chain includes an instrumentation amplifier (INA) with the gain set by an external

“Smart” lithium-ion battery would warn users if it is going to ignite

Electronics News Updates / By

There have been numerous cases of lithium-ion batteries catching fire in everything from mobile phones and laptops to cars and airplanes. While the odds of this occurring are low, the fact that hundreds of millions of lithium-ion batteries are produced and sold every year means the risk is still very real. Researchers at Stanford University
