Requirement High Speed ADC

Category: Hardware

Hi Team,

Im new to the design of ADC for 4-20mA analog Input and industrial applications. I have attached the complete design requirement.
Could you please have a look on my attached requirement sheet and share the below Inputs.

1) Suggest ADC part number for below spec?


•Number of channels:1 channel (1 channel or 4 channel in a single chip)
Resolution: 16 bit/14bit
Sample rate : 125Msps
•Digital output interface: SPI
•Analog Input specification: 4-20mA galvanically isolated input.

2)If galvanic isolated ADC is not available, what the galvanic isolated front end circuit can be used? Is there any galvanic isolated amplifier?
