Selecting the appropriate pull-up voltage allows flexible selection of the voltage value to be converted. For example, a ±5 V signal can be converted to a 3 V signal using the MAX972 comparator.

You can generate the positive and negative threshold voltages using a precision voltage reference that powers a resistor divider (not shown) or by driving the inputs with DACs if you need a digitally ...

Although humble in concept, today’s voltage comparators perform a simple basic task: comparing two voltages to determine which is larger. To accomplish this task, they accept two analog signals and ...

A comparator circuit (Fig. 1) compares two input voltages and outputs a binary signal indicating which is larger. If the non-inverting (+) input is greater than the inverting (−) input, the ...

A calmer arrangement of this comparator concept with a much lower gain figure can be used as the control section of a regulated series power supply. In Fig. 8, actually an inverting comparator, a ...

Voltage at the comparator's inverting input swings between 1.8 and 3.0 V. Also, making R1 = R2 sets the noninverting input voltage to 2.5 V.

The four comparators form a current detection circuit which can be used to indicate the four states of the input current, with resistors "Shunt" used to convert the input current into a voltage ...
