INTERFACING THE THS10064 TO THE TMS320C6201 DSP
The following application circuit shows an interface of the THS10064 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 THS10064 features four analog input channels. These can be configured for either single-ended or differential
operation. Best performance is achieved in differential mode. Figure 42 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:
