functional description
The THS1240 uses a differential pipeline architecture and assures no missing codes over the full operating
temperature range. The device uses a 1 bit per stage architecture in order to achieve the highest possible
bandwidth. The differential analog inputs are terminated with a 1-k
resistor. The inputs are then fed to a unity
gain buffer followed by the S/H (sample and hold) stage. This S/H stage is a switched capacitor operational
amplifier-based circuit, see Figure 3. The pipeline is a typical 1 bit per stage pipeline as shown in the functional
block diagram. The digital output of the 12 stages is sent to a digital correction logic block which then outputs
the final 12 bits.
