Hi I want use 10bit ADC in my project. What are the popular 10bit ADC thank you
"I want use 10bit ADC in my project.I want use 10bit ADC in my project." So this must be purely a learning exercise? In that case, you should start by considering what 10-bit ADCs you can actually obtain easily and within your budget. Otherwise, this is entirely the wrong way to proceed! The first thing to do is to define your Requirements: * What do you need to measure? * What are its parameters? * What are your other design constraints? Having established the requirements, only then should you start thinking about a solution! You are starting with a solution (10-bit ADC) and working backwards to a question!
LPC2138 has a 10-bit ADC on-chip. See http://www.keil.com/dd - Parameteric Search
What supply voltage? What input type - differential? single-ended? What input range? What sample rate / conversion speed? What sort of interface - I2C? SPI? Parallel? etc, etc... Remember: 10 bits means that each step in the digital output is 1/1024 of the full scale; ie, about 0.1% For this to be of any use, all the other errors in the rest of your circuit - noise, tolerances, etc - need to be well below 0.1% Precision analogue design is not trivial!
