When VIN is low, the output is also low. For the output to switch from low to high, VIN must rise to VIN1. Use Equation 4 to calculate VIN1. (4) When VIN is high, the output is also high. For the comparator to switch back to a low state, VIN must drop to VIN2 such that VA is equal to VREF. Use Equation 5 to calculate VIN2. (5) The hysteresis of this circuit is the difference between VIN1 and VIN2, as shown in Equation 6. (6) Figure 35. TLV703x in a Noninverting Configuration With Hysteresis |
