7.2.1.2 Detailed Design Procedure

Configure the circuit as shown in Figure 7-3. Connect VCC to a 3.3V power supply and VEE to ground. Make R1, R2, and R3 each 10MΩ resistors. These three resistors are used to create the positive and negative thresholds for the window comparator (VTH+ and VTH–). With each resistor being equal, VTH+ is 2.2V and VTH- is 1.1V. Large resistor values such as 10MΩ are used to minimize power consumption. The sensor output voltage is applied to the inverting and noninverting inputs of the two TLV704x devices. The TLV704x is used for the open-drain output configuration. Using the TLV704x allows the two comparator outputs to be wire-ored together. The respective comparator outputs are low when the sensor is less than 1.1V or greater than 2.2V. VOUT is high when the sensor is in the range of 1.1V to 2.2V.
