AFE5807: AFE5807 vs AFE5808(A)

Part Number: AFE5807

Hello,

My customer has a question about AFE5807 and AFE5808(A).

[Q]

Please tell me the difference between AFE5807 and AFE5808(A).

<My understanding>

* Analog Front-end : Same

* ADC : Different

  * ADC SNR : AFE5808(A) > AFE5807

  * ADC Sampling Rate : AFE5807 > AFE5808(A)

Therefore,

If SNR is more important than maximum sampling rate then AFE5808(A) is suitable.

If maximum sampling rate is more important than SNR then AFE5807 is suitable.

Is my understanding correct ?

Best Regards,

Hiroshi Katsunaga
