Figure 7. 3-Bit (8-Position) Delta-Sigma Example
Figure 8. DAC OFFSET LUTs
When temperature controlled, the DACs are updated
after each temperature conversion.
The reference input, REFIN, is the supply voltage for the
output buffer of all four DACs. The voltage connected to
REFIN and its decoupling must be able to support the
edge rate requirements of the delta-sigma outputs. In
a typical application, a 0.1FF capacitor should be con-
nected between REFIN and ground.
