AFE4300: Regarding analog front-end devices for body water measurement applications

Part Number: AFE4300
Other Parts Discussed in Thread: AFE4960P, , AFE4500

Tool/software:

Hi team,

My customer is looking for an AFE (Analog Front End) that can perform BIA (Bioelectrical Impedance Analysis) using a body water content measurement device.

I believe suitable products to introduce would be the AFE4300, AFE4500, and AFE4960P.

However, the customer's first choice is the MAX30009 from ADI, which puts us at a considerable disadvantage in terms of price and performance. Are there any other devices that could be recommended?

Best regards,

Kyohei
