i want to interface adc to 8051 to sample voltage and current and calculate power is it better to start off with serial or parallel adc. please suggest some adc
That depends on the speed you need and the available number of IO lines on your micro. Serial A/Ds are very popular these days.
As a 12-bit A/D I can suggest the ADS7841 (4-ch) or ADS7844 (8-ch) from TI, very reasonably priced. The MAX1247 is pin-compatible with the ADS7844, but also includes an internal reference.
TI also offers pin-compatible 16--bit A/D's, the ADS8341 and ADS8344, but more expensive.
All of them are very good converters.
Use them with a good reference, such as REF198 (4.096V) from Analog Devices.
u can use c8051f005 which have built in adc
u can have the interface on 8051 tutorial sites
if u want to connect the adc chip then 0808 is good for it
keep on doing it best of luck
