I build a 8 channel data acquisition system using " ADS7813P 16BIT ADC, SERIAL O/P, 7813, PDIP16" ADC.
ADS7813P is so expansive so I plane to change the " ADS7813P 16BIT ADC, SERIAL O/P, 7813, PDIP16" to "PCM1808PWR ADC, 24BIT, 96KSPS, 5.5V, 14TSSOP".
"ADS7813P" Price is Rs 3333 and "PCM1808PWR" price is Rs 195 only.
In my application no need to high sampling rate, Please help me to identify a low cost ADC with good Resolution.
why that much price difference?

Thanks Joseph Wu,
My System Details is
Data rate --------- i am reading temperature using thermonuclear and RTD so no need to high data rate.Desired resolution and what amount of noise can you tolerate? ---------- i need high resolution Do you need gain -------- No i already used INA129 for gain Number of input channels ------ 8 channelType of interface (I2C? SPI?) ------ no issue i can used both type of interface Are you limited in the amount of power needed? ------- no limited
Please tell me can i used "PCM1808PWR ADC, 24BIT, 96KSPS, 5.5V, 14TSSOP" instead of "ADS7813P 16BIT ADC, SERIAL O/P, 7813, PDIP16".
also guide me how to select the ADC
