Counter type ADC: A
Dual slope ADC: B
SAR type ADC: C
Flash ADC: D
The correct order of conversion time (T) of the ADCs shown above is –
TA< TB < TD< TC
TD< TC< TA< TB
TA< TB< TC< TD
TD< TC< TB< TA
For n-bit ADC of different type the conversion times are as follows –
Counter type (TA) = 2n TCLK
Dual slop (TB) = 2n+1 TCLK
SAR type (TC) = n TCLK
Flash type (TD) = TCLK
