10.2.2.2 Detailed Design Procedure

The inverting comparator circuit applies the input voltage (VIN) to the inverting terminal of the op amp. Two resistors (R1 and R2) divide the supply voltage (VCC) to create a midsupply threshold voltage (VTH) as calculated in Equation 5. The circuit is shown in Figure 10-3. When VIN is less then VTH, the output voltage transitions to the positive supply and equals the high-level output voltage. When VIN is greater than VTH, the output voltage transitions to the negative supply and equals the low-level output voltage, VTH.

Equation 5. V T H   =   R 2 R 1 + R 2   ×   V +   =   2.5   V
