NOTES:
3. The total resistance of R1 + R2 + R3 of 50k
is preferred to minimize error due to DACHI and DACLO input currents. Choose the values within
this limitation such that the voltages at DACHI and DACLO are those desired for the high and low limits of the programming range. For example,
Choosing R1 and R2 to be 15K and R3 to be 20K will produce a DAC range of 2.0V to 3.5V.
4. DAC Output Error as defined here assumes that the voltages applied to DACHI and DACLO are exact. The limits include errors introduced by
source impedance up to 12.5K and DACHI and DACLO. The error in Vdachi and Vdaclo (i.e. VREF5 error + external resistor divider error) must
be included to arrive at the total BDAC output error.
