Comparator with time out
The MC1422 functions as a comparator with the input at Pin 5. The frequency of the output pulses, dependent on the values of R2 and C1 as indicated, is approximately 2 Hz, with a pulse width of 0 ms at...
Dual-limit-microvolt-comparator
When the upper or lower limit is exceeded, the LED lights up. Positive feedback to one of the nulling terminals creates 5 to 20 pV of hysteresis on both amplifiers. This feedback changes the offset voltage of the LT1002 by...
Window Comparator Circuit
IC1-c functions as a non-inverting comparator, while IC1-a operates as an inverting comparator. Potentiometer R1 and fixed resistors R2 and R3 create a voltage divider chain that provides slightly different voltages to the two comparators. These voltages establish the upper...
Hi-Low level comparator
The voltage to be compared is fed through diodes D1 and D2 to the voltage dividers R1 and R5, where the low and high limits are established. When the input signal voltage exceeds the high threshold limit set with potentiometer...
Suitable comparator circuit headset detection
A headphone type detection circuit is illustrated in the attached figure. The 2.2k RMIC-BIAS resistor connected to the audio controller provides a low-noise reference voltage (VMIC-REF). When the audio jack is inserted, the VMIC-REF voltage through RMIC-BIAS is applied to...
Window comparator
This circuit produces an output of 0V when the input voltage is within a specified range defined by two reference voltages. When the input voltage falls outside this range, the output becomes positive. Two operational amplifiers (op-amps) function as voltage...
Comparator-latch
The main advantage of this circuit, in comparison to other comparators, is its capability to latch once the input surpasses a specified threshold level. When the input goes beyond this threshold, the output of the LM311N rises. This change activates...
simple magnitude comparator
In designing a logic circuit, it is often necessary to compare the values of two digital data inputs. Creating a custom magnitude comparator can lead to increased use of logic integrated circuits (ICs), as well as greater time and cost...
Four-channel-comparator
When operated as an open loop without compensation, the HA-2400 functions as a comparator with four selectable input channels. The clamping network at the compensation pin limits the output voltage, enabling DTL or TTL digital circuits to be driven with...
