Hi,
I my application i need to measure RPM from the pulse meter output 4-20ma. i am using ADS8344 16-bit adc and 250 ohm resistor for converting 4-20ma to 0-5v. I am using REF02,5V voltage reference,IC for ADC Vref. I have problem with ADC reference. 1. REF02 ic is getting heat and burned when i connect the pulse meter to adc input 2. i connected the 5V SMPS directly to ADC Vref pin, now ADC is burnned. i dont know what the problem is please help me to solve this issue.
