[SOLVED] which affordable uC has fastest onchip adc

[jimmy_tag]

I am using Atmega32L for my project its giving ADC conversion time as 65 - 260µs.

Is there any other µC faster than this one..

 

[ckshivaram]

32 bit controllers have less conversion time
E.g.
10 bit conversion time >= 2.44 uS( LPC2129 or most of its variants)

The dspic series from microchip have sampling rates as fast as 1.1MSPS (mega samples per second) means that they have conversion times less than 1usec.

Take a look at the ADuC7020 (and such) from Analog Devices - a smallish, relatively cheap ARM, integrated bootloader. It has a 12bit ADC with almost 1MSps and a fair amount of other stuff.

Hi,
Since you use ATMEGA, look at ATxMEGA which has 12-bit 2Msps ADC. You can sample 4 inputs in 1.5us (check the datasheet for this, I don't use this) with 1x to 64x software selectable gain and internal 1.00V reference.

Hope this helps.
