LM293ADRG4 Typical application Circuitry

LM293ADRG4

A dual differential comparator chip for precise voltage comparison applications is the LM293ADRG4. It is widely used in various electronic circuits to compare two voltages and provide a digital output indicating which voltage is higher.

Applications: The LM293ADRG4 finds use in diverse scenarios, including sensor signal processing, window comparators, level shifting, and analog-to-digital converters.

Parameters: This LM293ADRG4 chip operates within a wide supply voltage range of 2V to 36V, with a low input offset voltage of 2mV and a low supply current of 0.8mA. Because of its quick reaction time, it can be used in high-speed applications.

Circuit Design for a Window Comparator:

1. Power Supply: Connect the positive supply voltage (Vcc) to pin 8 and the ground to pin 4 of the LM293ADRG4. A supply voltage of 5V is commonly used.

2. Reference Voltages: Set upper and lower reference voltages using voltage divider circuits. For the upper reference, connect a 10kΩ resistor from Vcc to pin 3 (non-inverting input of the second comparator) and another 10kΩ resistor from pin 3 to ground, creating a 2.5V reference. For the lower reference, repeat this setup with pin 6 (non-inverting input of the first comparator).

3. Input Voltage: Connect the voltage to be compared to both pin 2 (inverting input of the second comparator) and pin 5 (inverting input of the first comparator).

4. Result: Pins 1 and 7 are where the comparators' outputs are accessible. Attach a 1kΩ pull-up resistor to Vcc on each output pin. When the input voltage falls within the reference voltages' defined window, the output will be high; otherwise, it will be low.

5. LED Signals: Connect an LED in series with a 220Ω current-limiting resistor from each output pin to the ground to visually represent the output state. When the input voltage is outside the window, the LEDs will turn on.

Design Considerations:

- Hysteresis: Add hysteresis by connecting feedback resistors between the output and the non-inverting input of each comparator to prevent false triggering due to noise.

- Decoupling of Power Supply: To remove supply line noise, put a 0.1µF ceramic capacitor near the power supply pins.

- Input Protection: Use clamping diodes or voltage dividers to protect the input pins if the input voltage can exceed the supply voltage.

Incorporating the LM293ADRG4 into your circuit design following these guidelines can create an efficient window comparator suitable for various applications, ensuring precise voltage comparison and reliable operation.
