Product details

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.

Features

1 Weight-scale front-end:.
Supports up to four load cell inputs.
On-chip load cell 1.7-V excitation voltage for ratiometric measurement.
68-nVrms Input-Referred noise (0.1 Hz to 2 Hz).
Best-fit linearity: 0.01% of full-scale.
Weight-scale measurement : 540 µA.
Body composition front-end:.
Supports up to three tetra-polar complex impedance measurements.
6-Bit, 1-MSPS sine-wave generation digital-toanalog converter (D.
