PRINCIPLES OF OPERATION
operating configuration examples (continued)
Figure 27 shows an example of top/bottom mode operation on an input span of 800 mV with mid-scale value
1.5 V. Pin REFTS is set to 2.5 V and pin REFBS to 0.5 V, making their average value equal to the mid-scale
value of AIN and giving the maximum specified difference of 2 V between REFTS and REFBS to maximize the
full-scale range of the ADC core for best resolution. The PGA gain then has to be set to 2.5, to amplify the
800 mVPP input signal to 2 VPP at the ADC core input.

Figure 28. Schematic of Clamp Circuitry
The THS1031 provides a clamp function for restoring a dc reference level to the signal at AIN which has been
lost through ac-coupling from the signal source to this pin.
Figure 29 shows an example of using the clamp to restore the black level of a composite video input ac coupled
to AIN. While the clamp pin is held high, the clamp amplifier forces the voltage at AIN to equal the clamp
reference voltage, setting the dc voltage at AIN for the video black level.
After power up, the clamp reference voltage is the voltage on the CLAMPIN pin. This reference can instead be
taken from the internal CLAMP DAC by suitably programming the THS1031 clamp and control registers.
Clamp acquisition and clamp droop design calculations are discussed later.
