Figure 14. Input Mode Configurations
The gain of the sample and hold changes with the CON1 and the CON0 inputs. Table 2 shows the gain of the
sample and hold and the levels applied at the AIN+ and AIN– analog inputs for Mode 1 and Mode 2. The
common mode level for the two analog inputs is at AVDD/2.

Table 2 assumes that the delta in ADC reference voltages VREFT and VREFB is set to 1 V, i.e., VREFT – VREFB = 1
V. Note that VREFB and VREFT can be set externally, which will scale the numbers given in this table.
The user-chosen operating configuration and reference voltages determine what input signal voltage range the
THS1230 can handle.
The following sections explain both the internal signal flow of the device and how the input signal span is related
to the ADC reference voltages, as well as the ways in which the ADC reference voltages can be buffered
internally or externally applied.
Figure 15 shows the signal flow through the sample and hold unit and the PGA to the ADC core.
