Figure 35. Bipolar Operation
The output voltage of this circuit for any code is found to be
V
O
= (V
A
x (D / 1024) x ((R1 + R2) / R1) - V
A
x R2 / R1)
where
• D is the input code in decimal form
• With V
A
= 5V and R1 = R2 (5)
V
O
= (10 x D / 1024) - 5V (6)
A list of rail-to-rail amplifiers suitable for this application are indicated in Table 2.
