WebThe output signal remains constant as the differential input voltage changes. When described that way, the comparator resembles a 1-bit ADC. Comparing Comparators and Op Amps. An op amp running without negative feedback can serve as a comparator, because its high voltage gain enables it to resolve very small differences in input voltage. WebThis reference voltage has relatively high output impedance, since it is designed to be input to a comparator; therefore, this output should be buffered in most cases. Without a buffer circuit, you can still look at the output voltage using a high-impedance input like a voltmeter or an oscilloscope.

WebIC5 is a bandgap reference whose 1.2V output is buffered by op amp IC2d to provide a reference voltage for the dual DACs in IC4. This reference voltage is also doubled by the gain-of-2 amplifier IC2c to provide a 2.5V dc level at the comparator's noninverting input. DAC A applies 0V to 3.8V at the comparator's inverting input. WebThe input offset voltage (VIO) can be defined as the differential input voltage to apply in order to be at the toggling level. Input offset voltage limits the resolution of comparators. Therefore, for very small signals (in the same order as the V IO), the comparator toggles at an undesired value or does not toggle at all. Figure 7.

"WebAlso called the parallel A/D converter, this circuit is the simplest to understand. It is formed of a series of comparators, each one comparing the input signal to a unique reference voltage. The comparator outputs connect to the inputs of a priority encoder circuit, which then produces a binary output. The following illustration shows a 3-bit flash ADC circuit: " - Comparator reference voltage the same input
