LM2901S14-13 Linear - Comparators

The LM2901S14-13 is a voltage comparator integrated circuit that is ideal for a number of applications. It is a dual 8-pin SOT-23-6 package logic level device that is designed for operation with low-power linear and logic signals. Literally, LM2901S14-13 is a low-power device that is capable of producing an output voltage when two input signals are not the same. It generates a voltage output when two input signals are different at the input pins of A and B. The LM2901S14-13 comparison circuit provides high speed, low power operation that exceeds the performance of other comparators available in the market today. With these features and advantages, the LM2901S14-13 can provide improved performance in a variety of applications such as optoelectric system use, intersection detection and data acquisition systems.

Working Principle

The LM2901S14-13 is designed to operate under the comparator principle. This means that the LM2901S14-13 will compares two input voltages and produces an output based on their relative magnitude. The LM2901S14-13 has two input voltage pins which is A and B. The A and B pins are connected to an external circuit, and when the voltage at the A pin is greater than the voltage at the B pin, a HIGH output is generated. On the other hand, if the voltage at the B pin is greater than the voltage at the A pin, a LOW output is generated. The LM2901S14-13 can also be used as a non-inverting comparator. In non-inverting mode, the output is the same as the input when the A pin is more positive than the B pin. When the B pin is more positive than the A pin, the output is opposite to the input.

Features and Advantages

The LM2901S14-13 has a number of features and advantages. Firstly, it offers high speed operation which is approximately 10 ns with a power dissipation of 1 µW. Secondly, its common mode range extends from VSS to VDD minus 1.5 V, whereas the input voltage range for A or B is from 0 V to 5 V. Additionally, the LM2901S14-13 offers logic inverting and non-inverting outputs, which enable the user to realize their interactive and logic based systems. The two inputs of this device are protected with diodes. The LM2901S14-13 comparator also has low and high-level output stages which are able to drive either a CMOS or non-CMOS logic. Furthermore, the power supply port features protection diodes for ESD protection. The LM2901S14-13 is also equipped with hysteresis for H/L output logic. This hysteresis feature has three selectable levels of 1V, 2V, and 3V and is extremely useful in rejecting slowly changing signal in noisy environments. This is enabled by the TTL compatible integrated Schmitt trigger within the comparator.

Applications

The LM2901S14-13 comparator is applicable in a range of electronic circuits. Firstly, in low speed and power utilization applications, the LM2901S14-13 can be applied in analog to digital converters, signal switches, and specialized transducer bridges. In other applications, the LM2901S14-13 can be used as a signal conditioner. It can condition any kind of analog signal such as temperature and pressure. The LM2901S14-13 is also applicable in industrial process control. The comparator can monitor temperature levels, power line phase, control systems, and motor phase detection systems. Moreover, it can be used in communication systems, motion detectors, security alarms, automotive circuits, and medical instrumentation.

Conclusion

In conclusion, the LM2901S14-13 is a dual 8-pin SOT-23-6 package logic level device that is designed for operation with low-power linear and logic signals. It provides a HIGH or LOW output when the input voltage at pin A is higher or lower than the voltage at pin B respectively.
