First weigh scale and body composition analog front end is unveiled
August 02, 2012 // Paul Buckley
Texas Instruments Incorporated has unveiled what is claimed to be the industry's first fully integrated analog front end for both weight and body composition measurement (BCM).
The AFE4300 is an easy-to-use, precision, low-power front end solution, which allows engineers designing weigh scales that incorporate body composition meters, body impedance analyzers, and impedance measurement equipment to get their products to market faster than by implementing existing, more complex multi-chip solutions.
The AFE4300 incorporates two separate signal chains, one targeting weight measurement and the other targeting body composition analysis, with a 16-bit, 860-sps analog-to-digital converter (ADC) multiplexed between them. The device's three BCM channels enable segmental body impedance analysis (BIA) between body extremities, which allows for a full picture of the subject's body composition.
The AFE4300 integrates two separate signal chain front ends for weigh scale and dual body composition measurements into a single device, so that little to no in-house expertise is required to quickly add body composition measurements to weigh scales applications.
The device’s tetra-polar measurements eliminate electrode impedance-related inaccuracies. In addition, the device's three BCM channels enable segmental body impedance analysis (BIA) for measurement across the body including hand to hand, foot to foot, or even hand to foot, which increases overall measurement accuracy. The device also includes an option to accurately measure Extra Cellular Water (ECW) and Intra Cellular Water (ICW) using bio-impedance spectroscopy (BIS).
The AFE4300 consumes less than 1 mA, operating from a 2-V to 3.6-V power supply, to extend battery life.
Availability and Pricing
The AFE4300 is available now in a 12-mm x 12-mm TQFP-80 package. It is priced at $2.50 in quantities of 1,000.
