digital output data format

The digital output data format of the THS10064 can either be in binary format or in two’s complement format.

The following tables list the digital outputs for the analog input voltages.

Table 3. Binary Output Format for Single-Ended Configuration

SINGLE-ENDED, BINARY OUTPUT

ANALOG INPUT VOLTAGE

DIGITAL OUTPUT CODE

AIN = VREFP

3FFh

AIN = (VREFP + VREFM)/2
