I have a question about the isolated-ADC
Currently AMC1305Mx(CMOS) is used on the board.
It looks like AD7401A is pin-compatible with it.
Are there any concerens when we will replace AMC1305Mx with AD7401A?
I noticed that pin1 is a bit…
I evaluate the AD7401A with a shunt resistor (Vishay PG CSM3637 - 2mohm) as a current sensor for a multilevel-inverter design in each phase.
From the datasheet, figure 23 I have learned the the potential on VIN- of the AD7401A should normaly…
I have a question about AD7401
Is it okay to connect Pin4 to GND?
If it's connect to GND, what would happen?
*According to the datasheet, it says Pini4 to 6 treated as NC(Non connect)
I have a question about AD7403, New Isolation ADC.
Does AD7403 improve analog specs compared to AD7401A?
What are the highlights of AD7403 compared to AD7401A?
The AD7400A and the AD7401A parts are our parts that are targeted at shunt current monitor applications.
They accept signals in the +/-250mV range and have in-built isolation based on ADIs iCoupler technology.
The output of the AD7400A and…
The internal clock on the AD7400 and AD7400A is used to clock the converter internally and also to allow the user to clock out the data bits from the modulator into an FPGA for example or other receiving device.
This clock typically runs…
I have a question here.I was just going through the AD7401A data sheet. And trying to implement the second order delta modulator. From the Page 14 of the AD7401A data sheet theere is a statement saying that "
The analog input signal is continuously…
I moved this question about the AD7401A to the Precision ADCs Community. Someone here should be able to assist you with it.

There are a few factors to consider that leads to the increased current consumption. The AC and DC performance of the AD7403 is much better in the AD7403 when compared to the AD7401A. For example the minimum SINAD for the AD7401A is 72dB however the…
FMCMOTCON1 provides electrical isolation between the FPGA and the power stage.
The components used to provide electrical isolation are:
- ADuM7640 for digital signals
- AD7401A for analog signals
- ADuM500 for power supplies
