The output voltage can be set using the VSEL pin. The resistor divider ratio for VSEL programs the VOUT_COMMAND range, VOUT_SCALE_LOOP divider, VOUT_MIN, and VOUT_MAX levels according to Table 6-12. Select the resistor divider code for the range of VOUT desired. For this 1-V output example, resistor divider code 2, a single resistor to AGND or floating the VSEL pin can be used.

With the resistor divider code selected for the range of VOUT, select the resistor to AGND code with the VOUT_COMMAND offset and VOUT_COMMAND step from Table 6-13. To calculate the resistor to AGND code subtract the VOUT_COMMAND offset from the target output voltage and divide by the VOUT_COMMAND step. For this example, a single resistor to AGND was used and the result is code 6. A 14.7-kΩ resistor to AGND at VSEL programs the desired setting.
