Figure 22. ADC Reference Generation, MODE = AVDD/2
Connecting MODE to AVDD or AVDD/2 enables the internal ADC references buffer A2. The outputs of A2 are
connected to the REFT and REFB pins and its inputs are connected to pins VREF and AGND. The resulting
voltages at REFT and REFB are:

Depending on the connection of the REFSENSE pin, the voltage on VREF may be driven by an off-chip source
or by the internal bandgap reference A1 (see onboard reference generator) to match the THS1040 input range
to their application requirements.
When MODE = AVDD the BIASREF pin provides a buffered, stabilized AVDD/2 output voltage that can be used
as a bias reference for ac coupling networks connecting the signal sources to the AIN+ or AIN inputs. This
removes the need for the user to provide a stabilized external bias reference.
