ADC to PC interface circuit plz...

[Bhanumurthy]

Hi All,
Plz tell me what is the appropriate interface circuit to interface ADC to a personal computer.The objective is - the output of ADC should be read as input by the C-program in PC.
Plz help me by sending few detailed circuits.

Regards.

you can use a micro controller to read adc value and it serially to the PC...
or there are serial ADC's available that you can directly interface to the PC via serial port....
such as MAX11102, MAX11103, etc...

Measurement Computing make USB based data acquisition systems
USB DAQ Data Acquisition from Measurement Computing

easy to use with software support for Visual C++, VB, Matlab, Labview, etc

However, they are fairly expensive. A cheaper alternative is to build you own using a microcontroller

Hi,

I have made a similar project. The Device is a AVR ATmega32 running a firmware which responds to requests from a PC. The interface is UART with a USB to UART bridge CP2102 on PC side.

The PC side software Visualize data in form of a graph using GDI

Hope this helps.
