Figure 1
The TLV571 is a successive-approximation ADC utilizing a charge redistribution DAC. Figure 1 shows a
simplified version of the ADC.
The sampling capacitor acquires the signal on Ain 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.
sampling frequency, fs
The TLV571 requires 16 CLKs for each conversion, therefore the equivalent maximum sampling frequency
achievable with a given CLK frequency is:
fs(max) = (1/16) fCLK
The TLV571 is software configurable. The first two MSB bits, D(7,6) are used to address which register to set.
The remaining six bits are used as control data bits. There are two control registers, CR0 and CR1, that are user
configurable. All of the register bits are written to the control register during write cycles. A description of the
control registers is shown in Figure 2.
