Parameters	Dual Slope ADC	Flash ADC	SAR ADC	Sigma-delta
Resolution	High	Low	Medium	High
Cost	Medium	High	Low	Low
Accuracy	High	Low	Medium	Low
Speed	Slow	Very Fast	Medium-Fast	Slow
Resolution (Bits)	12-18	4-12	8-16	12-24
Disadvantages	Slow Conversion rate. High precision external components required to achieve accuracy.	High power Consumption, large size	Speed Limited to 5Msps	Slow due to oversampling
Conversion Time	Conversion time doubles with every bit increase in resolution.	Conversion Time does not change with increased resolution.	Increases linearly with increased resolution.	Trade-off between data output rate and noise free resolution.
Encoding Method	Analog Integration	Thermometer Code Encoding	Successive Approximation	Over-Sampling Modulator, Digital Decimation Filter
