Dear Technical Support Team,
I have some question about DRV401.
1.)
The datasheet shows "GAIN FLATNESS vs FREQUENCY" below.
Could you tell me the reason why each "Normalized Gain" of M4645-X08 and X211 and X600 are different ?
Is it caused by the difference of eah functions?
2.)
How do I select the value of R3,R4,C4,C3 on Figure 8. Basic Connection Circuit?
Does they affect GAIN FLATNESS?
The datasheet doesn't show how to select the value of resister and capacitance.
----------------------------------------
R3 and R4, together with C3 and C4, form a network
that reduces the remaining probe oscillator ripple in
the output signal. The component values depend
on the sensor type and are tailored for best results.
This network is not required for normal operation.
Best Regards,
