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 40 shows a simplified model, where a single-ended
configuration for channel AINP is selected. The reference voltages for the ADC itself are VREFP and VREFM (either internal
or external reference voltage). The analog input voltage range goes from VREFM to VREFP. This means that VREFM defines
the minimum voltage, which can be applied to the ADC. VREFP defines the maximum voltage, which can be applied to the
ADC. The internal reference source provides the voltage VREFM of 1.5 V and the voltage VREFP of 3.5 V. The resulting
analog input voltage swing of 2 V can be expressed by:
