8.4 Device Functional Modes

8.4.1 Setting Voltage and Current Output Ranges

For voltage and current outputs in normal mode (VOUT and IOUT are not simultaneously enabled), the output

range is set according to Table 8-7.

Table 8-7. RANGE Bits vs Output Range

RANGE

OUTPUT RANGE

000

0 V to +5 V

001

0 V to +10 V

010

±5 V

011

±10 V

100

Not allowed(1)

101

4 mA to 20 mA

110

0 mA to 20 mA

111

0 mA to 24 mA

(1)

RANGE bits cannot be programmed to 0x100. Previous value is held when this command is written.

Note that changing the RANGE bits at any time causes the DAC data register to be cleared based on the value

of CLR-SEL (pin or register bit) and the new value of the RANGE bits.

In addition to the RANGE bits, the OVR bit extends the voltage output range by 10%. if the OVR bit is set, the

voltage output range follows Table 8-8, as long as there is headroom with the supply.

0 V to 5 V

0 V to 5.5 V

0 V to 10 V

0 V to +11 V

±5 V

±5.5 V

±11 V

When VOUT and IOUT are simultaneously enabled (dual-output mode) by setting DUAL OUTEN in the

Configuration Register, the voltage output is controlled by RANGE in the Control Register (see Table 8-9),

and the current output is controlled by IOUT RANGE in the Configuration Register (see Table 8-10).
