detailed description
The TLC4541/5 are successive approximation (SAR) ADCs utilizing a charge-redistribution DAC. Figure 22
shows a simplified version of the ADC. The sampling capacitor acquires the signal on AIN (or the AIN(+) pin for
TLC4545) during the sampling period. When the conversion process starts, the SAR control logic and charge
redistribution DAC are used to add and subtract fixed amounts of charge from the sampling capacitor to bring the
comparator into a balanced condition. When the comparator is balanced, the conversion is complete and the
ADC output code is generated.
