9.3.1 Design Requirements

• VCC must be within valid range per Section 6.6. This example uses a value of 12 V for VCC.

• Input voltage must be within the recommended common-mode range, as shown in Section 6.6. The valid

common-mode range is 4 V to 12 V (VCC– + 4 V to VCC+).

• Output is limited by output range, which is typically 1.5 V to 10.5 V, or VCC– + 1.5 V to VCC+ – 1.5 V.

9.3.2 Detailed Design Procedure

• Avoid input voltage values below 1 V to prevent phase reversal where output goes high.

• Avoid input values below 4 V to prevent degraded VIO that results in an apparent gain greater than 1. This

may cause instability in some second-order filter designs.
