Part Number: AFE5809 Hi there, we are using AFE5809 for medcial ultrasound application. two questions. 1. From IC's internal structure, does AFE5809 and AFE5808A share the same IC design, except that 5809 has an additianal IQ demodulator? Also, they share the same IC PCB footprint? 2. For Capacitor Bypass which connected to INMx pins, it is wrote "This DC offset correction circuit has a high-pass response and can be treated as a HPF. the corner frequency scales almost linearly with the value of the CBYPASS". Could you explain in detail that how will this cap influence the DC offset correction circuits? we are not sure how to choose the corner frequency. Is there any recommend vaule in Ultrasound application, and why? Thanks a lot!
