PRINCIPLES OF OPERATION
functional description
The TLV5510 is a semiflash ADC featuring two lower comparator blocks of four bits each.
As shown in Figure 19, input voltage VI(1) is sampled with the falling edge of CLK1 to the upper comparators
block and the lower comparators block(A), S(1). The upper comparators block finalizes the upper data UD(1)
with the rising edge of CLK2, and simultaneously, the lower reference voltage generates the voltage RV(1)
corresponding to the upper data. The lower comparators block (A) finalizes the lower data LD(1) with the rising
edge of CLK3. UD(1) and LD(1) are combined and output as OUT(1) with the rising edge of CLK4. According
to the above internal operation described, output data is delayed 2.5 clocks from the analog input voltage
sampling point.
Input voltage VI(2) is sampled with the falling edge of CLK2. UD(2) is finalized with the rising edge of CLK3, and
LD(2) is finalized with the rising edge of CLK4 at the lower comparators block(B). OUT(2) is output with the rising
edge of CLK5.
