8 bit adc

which temperature sensor are you using and for what application

LM35 sensors…and also LDR sensor too…well we are developing an data acquisation system to store sensor data as many sensor(especially application is useful for small industries) to monitor all sensors data

i suggest you to use ADC 0848. it has eight multiplexed channels through which it recieves analog signal so you can connect both your lm 35 and ldr sensors by selecting an appropriate step size.

              adc0804 has only one input so you can give it input from either lm35 or ldr. also you must note that the output of adc0804 is an 8 bit parallel. then how can you send 16 bits

ya correct about adc0804 parallel data transfer and thank you pal. Can you please help me with SAR adc’s. i mean how data will be converted with an example( just for my info).

as i haven’t used sar adc, so i might not help in this regard.

its ok and thanks…pa if u have any materials on sar pls post it or mail to my id [email protected]…thank you

the following link might be helpful to you

there is a lot of material on internet about sar adc but i will send you some, that i found helpful.
