3 channel 4 - 20mA input to ADC

[freemanantony]

hai everybody,
i need to give 3 channels of 4 - 20mA input to ADC ,which ADC i can use for this type of inputs? can anyone help me on this

what processor are you using ?
For every processor there are set of registers where you can make setting for measurement of analog inputs.
what do you mean by 3 channels of 4 ?
what is 20 mA input to ADC where does it come from ?
what kind of inputs do you have ?

Ask questions appropriately !

i am going to use a separate ADC ic that is going to communicate with controller using spi or i2c.i need to give three (4 to 20 mA ) analog inputs which come from analog sensors

According to the info you have mentioned I can suggest using MAX1221/MAX1223/MAX1343

use ADC registers in your Microcontroller and once read your reading make necessary calculations for your requirement.
