Op-amp Comparator Summary. In this tutorial about the Op-amp Comparator we have seen that a comparator circuit is basically an operational amplifier without feedback, that is, the op-amp is used in its open-loop configuration, and when the input voltage, V IN exceeds a preset reference voltage, V REF, the output changes state.

Op-amp comparators dissipate more power in their saturation operating region. Op-amps tend to be more expensive than comparators. Op-amps may not be able to handle a wide voltage discrepancy between the inputs, they generally have a very small differential between the input voltages. But it's not all bad news for the op-amps - comparators

The transfer function for a comparator with hysteresis is shown in Figure 4. If the input voltage approaches the switching threshold (VOS) from the negative direction, the comparator will switch from a "0" to a "1" when the input crosses VOS + VH/2. The "new" switching threshold now becomes VOS - VH/2. The comparator output will remain in a

Comparators. A comparator is an electronic circuit, which compares the two inputs that are applied to it and produces an output. The output value of the comparator indicates which of the inputs is greater or lesser. Please note that comparator falls under non-linear applications of ICs. An op-amp consists of two input terminals and hence an op

Comparator operation occurs as a natural result of the op-amp's extremely high gain. As shown in the diagram below, the full gain (A OL) is applied to the difference between the voltage at the non-inverting input terminal and the voltage at the inverting input terminal. V OU T = AOL ×(V IN + −V IN −) = AOL ×V DIF F V O U T = A O L ×

Comparators are often used, for example, to check whether an input has reached some predetermined value. In most cases a comparator is implemented using a dedicated comparator IC, but op-amps may be used as an alternative. Comparator diagrams and op-amp diagrams use the same symbols. Figure 4 shows a comparator circuit.

Figure 2.3.1 2.3. 1: Comparator (single input). The op amp cannot produce 20,000 V. The data sheet lists a maximum output swing of only ± ± 13.5 V when using ± ± 15 V supplies. The output will be truncated at 13.5 V. If the input signal is reduced to only 1 mV, the output will still be clipped at 13.5 V.

TUTORIAL Using Op Amps As Comparators . Even though op amps and comparators may seem interchangeable at first glance there are some important differences. Comparators are designed to work open-loop, they are designed to drive logic from their outputs, and they are designed to work at high speed with minimal instability.
