The AFE4300EVM-PDK is an Evaluation Module for evaluate the operation and performance of the AFE4300, a weigh scale/body composition analogue-front-end. The AFE4300 incorporating two separate signal chains, one targeting weight measurement and the other targeting body composition analysis. The board provides access for load cell terminals to support up to four load cell inputs for weigh scale measurements, BCM terminals to support up to three tetra-polar complex impedance measurements. Users can also feed any type of single ended or differential signals directly to the AFE4300 through the auxiliary (AUX1 and AUX2) inputs. External support circuits such as anti-aliasing network for load cell terminals, trim-pot for setting the gain of the instrumentation amplifier at the weigh scale front-end, instrumentation amplifiers for the BCM differential terminals, load cell simulation block, impedance simulation block, clocks and external references are provided for testing purposes.
