TLV4011/Q1 Precision Comparators Texas Instruments TLV4011/Q1 Precision Comparators are low-power, high-accuracy comparator with a precision, integrated reference. Two external resistors can be connected to the input to create an adjustable voltage threshold down to 1.226V. The factory-trimmed switching threshold and precision hysteresis combine to make the TLV4011 appropriate for voltage and current monitoring in harsh, noisy environments where slow-moving input signals must be converted into clean digital outputs. Similarly, brief glitches on the input are rejected, thereby ensuring stable output operation without false triggering.
