UNLESS OTHERWISE NOTED, this document contains PRODUCTION DATA.
The DACx1001 outputs are unbuffered. Use an external op amp to buffer the DAC output. The DAC output voltage ranges from VREFPF to VREFNF. Two gain-setting resistors are integrated in the DACx1001. These resistors are used to scale the DAC output, minimize the bias current mismatch of the external op amp, and generate a negative reference for the REFNF pin. See the Embedded Resistor Configurations section for more information. Table 6 shows the op amp options for the output drive circuit.
