interfacing the THS1206 to the TMS320C6201 DSP
The following application circuit shows an interface of the THS1206 to the TMS320C6201. The read (using RD,
RD-controlled) and write timings (using WR, WR-controlled) shown before are valid for this specific interface.

analog input configuration and reference voltage
The THS1206 features four analog input channels. These can be configured for either single-ended or
differential operation. Best performance is achieved in differential mode. Figure 17 shows a simplified model,
where a single-ended configuration for channel AINP is selected. The reference voltages for the ADC itself are
V
REFP
and V
REFM
(either nternal or exteral reference voltage). The analog nput voltage range goes from V
REFM
to V
REFP
. This means that V
REFM
defines the minimum voltage, which can be applied to the ADC. V
REFP
defines
the maximum voltage, which can be applied to the ADC. The internal reference source provides the voltage
V
REFM
of 1.5 V and the voltage V
REFP
of 3.5 V. The resulting analog input voltage swing of 2 V can be expressed
by:
