LM293DR2 Typical application Circuitry

LM293DR2

The LM293DR2 is a part of the LM293 series of integrated circuits, known for their dual differential comparators. These devices are produced by Texas Instruments and are widely utilized in various electronic applications for comparing two input voltages. The LM293DR2, in particular, is distinguished by its capability to function efficiently across a wide range of supply voltages, and it can be used with both single and dual power supply configurations.

1. Inverting Input of Comparator 1 (Pin 1): This pin is the inverting input for the first comparator within the LM293DR2. This voltage and the voltage at the non-inverting input (Pin 2) are compared.

2. Non-Inverting Input of Comparator 1 (Pin 2): Serving as the non-inverting input for the first comparator, this pin is where the voltage is compared against the inverting input (Pin 1).

3. Output of Comparator 1 (Pin 3): The result of the first comparator's voltage comparison is outputted here. The output rises when the voltage at the non-inverting input (Pin 2) exceeds the voltage at the inverting input (Pin 1).

4. VCC (Pin 4): This pin is connected to the positive supply voltage. The LM293DR2 operates over a range of supply voltages, providing versatility in different electronic applications.

5. Output of Comparator 2 (Pin 5): This pin is the output for the second comparator. It indicates the result of the voltage comparison between the non-inverting (Pin 6) and inverting inputs (Pin 7).

6. Non-Inverting Input of Comparator 2 (Pin 6): This pin is the non-inverting input for the second comparator, where the voltage is compared with the inverting input (Pin 7).

7. Inverting Input of Comparator 2 (Pin 7): Acting as the inverting input for the second comparator, the voltage at this pin is compared with the non-inverting input (Pin 6).

8. Ground (Pin 8): For single-supply operations, this pin is connected to the ground. In dual-supply setups, it connects to the negative supply voltage.

9. Key Features of the LM293DR2:

- Versatility in Voltage Ranges: The LM293DR2 is capable of operating with a variety of supply voltages, adding flexibility to its use in different electronic configurations.

- Dual Comparator Design: Housing two comparators in a single package, the LM293DR2 allows for compact and efficient circuit designs.

- Single or Dual Supply Operation: This device can function with either a single power supply or with dual supplies, broadening its application range.

When designing with the LM293DR2, it is important to follow the guidelines provided in the datasheet, particularly concerning voltage ranges and output current limitations. The inclusion of pull-up or pull-down resistors on the output pins, as required by the specific application, is also essential. Additionally, ensuring that the input voltages do not exceed the supply voltage is crucial to prevent damage to the device.

In conclusion, the LM293DR2 offers a reliable solution for voltage comparison needs in various electronic applications. Its dual comparator setup and ability to operate under varying power supply conditions make it a valuable component for electronic designers.
