DIGITAL OUTPUT DATA FORMAT

The digital output data format of the THS1007 can either be in binary format or in twos complement format. The

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

Table 2. Binary Output Format for Single-Ended Configuration

SINGLE-ENDED, BINARY OUTPUT

ANALOG INPUT VOLTAGE

DIGITAL OUTPUT CODE

AIN = VREFP

3FFh

AIN = (VREFP + VREFM)/2

200h

AIN = VREFM

000h

Table 3. Two’s Complement Output Format for Single-Ended Configuration

SINGLE-ENDED, TWOS COMPLEMENT

ANALOG INPUT VOLTAGE

DIGITAL OUTPUT CODE
