#116761 - Low cost ADCs Responding to: ???'s previous message |
Dear Karim,
You have two options available. 1. Use a micrcontroller with internal ADC [ This is probably the lowest cost option considering board space cost and component costs ] Have a look @ Philips LPC9xx series microcontrollers there are many low cost 8051 core micros with internal ADCs. Unfortunately there are quite a few 8051s with ADCs in them and they are more expensive when you compare with equivalent AVR & PIC. If its not a strict requirement to use 8051 I would suggest you to have a look at AVR and PIC microcontrollers. Here in Mumbai PIC and AVR are more easily available and costs lesser too cant say anything about your area. 2. Use an external ADCs - There are many low cost ADCs available selection would depend on following. 1. Bus interface. 2. Resolution. 3. Speed. 4. No. of channels. etc. visit ADC chip manufacturers given below all of them have parametric search facility which will help you with your ADC selection. www.ti.com www.analog.com www.national.com www.maxim.com www.philips.com [ Philips doesnt make lots of ADCs for products like PCF8591 are worth looking at ] Regards, Prahlad Purohit |
