SNOSDG0 August 2024 TLV1H103-SEP
PRODUCTION DATA
A comparator may produce “chatter” (multiple transitions) at the output when there are noise or signal variations around the reference threshold; this causes the output to change states in rapid random successions as the comparator input goes above and below the threshold of the reference. This usually occurs when the input signal is moving very slowly across the switching threshold of the comparator. This problem can be prevented by using the internal hysteresis feature of the TLV1H103-SEP.
The TLV1H103-SEP has a LE/HYS pin that allows for variable internal hysteresis depending on the resistor value connected between the pin and VEE, where increasing the resistance decreases the hysteresis to a minimum level.
