ADC Interfacing : 8051 and MCP3202

[karan123]

Hello,

I am using "ADC0804 with Optocoupler" and 8051 for measuring Analog Voltage.

Now I want to use MCP3202 which is SPI Protocol Based, Becasue is required
Less pins to interface with 8051 Microcontroller.


I have read from datasheet that It required “Anti-Aliasing Analog"
which is MCP601".

My Question is that How I know MCP601 is require for me or not??


Thanks in Advance.

I think you have mixed up between requierment of low impedance input with anti-aliasing . Here MCP601 is a op-amp which will provide low impedance to the ADC input.

ADC MCP3202 and Op-amp

Thanks for reply..


Do i need of Op-amp MCP601 while using ADC for measuring high voltages.
