Compare different types of ADCs.
|Parameters||Dual Slope ADC||Flash ADC||SAR ADC||Sigma-delta|
|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|
