Lowpower ADC chip for digitizing 10Hz

Need low power ADC chip for digitizing 10-20Hz signal. 8bit is mandatory for me and to do 100Hz sampling or more. Can someone come in mind some chip

many thanks.

There should be plenty of them on the market: the best candidate will be SAR-type ADC or sigma-delta ADC. You can find them at www.maxim-ic.com. One of the candidate will be MAX1400.

Hi
you can use MAX113(3 channel) or 117(7ch+1 refrence) 3.3v flash ADC, I am using this for portable 1.5v based product.

I don't see the point of using flash ADC to convert 10~20Hz signal -- it is not efficient at all. Integration type or sigma-delta type ADC should be the natural choice.

Hi!
Please specify what do you mean by “low power”?
Power = ?,
Supply voltage = ?, etc.
There are good old 8-bits SAR ADC as ADC0801/2/3/4/5 which are really not very "low power" but may be will do the job?
