AMC1300: about clock frequency for delta-sigma

ACGUY

Part Number: AMC1300

Hello E2E,

How much the clock frequency for internal delta-sigma?

and

The ACM1301 data sheet provides an example of using a current sense amplifier for voltage sensing (Figure 51).
Can this R3 and R3'circuit be applied to the AMC1300?

Regards,
ACGUY

    Hi ACGUY,

    Unfortunately I cannot share internal parameters on the public forum, so I cannot specify the internal clock frequency. 

    Yes it can. Adding R3' will greatly reduce the offset seen at the inputs of the device created by the input bias currents, allowing for additional dynamic range. This voltage accuracy calculator may help:
