PRODUCTION DATA
The output buffer amplifier generates rail-to-rail voltages on the output, giving a maximum output range of 0 V to VDD. Equation 1 shows that the full-scale output range of the DAC output is determined by the voltage on the VREFIO pin, the reference divider setting (DIV) as set by the REF-DIV bit (address 4h), and the gain configuration for that channel set by the corresponding BUFF-GAIN bit (address 4h). The buffer amplifier is designed to have a 79º phase margin (nominal) at 380 kHz at room temperature.
