2.2.4 Hysteresis

The TLV3802EVM is able to support external hysteresis on the non-inverting side for channel 1 and the inverting side for channel 2. Input resistors R3 and R12 are 0-Ω resistors but can be replaced accordingly for desired amount of hysteresis. For channel 1, the feedback resistor is the combination of R2 and R4. Likewise, for channel 2, the feedback resistor is the combination of R10 and R13. All resistors must be populated. If external hysteresis is not required, then these optional feedback resistors can be left uninstalled.
