The LM293DG is an integrated circuit (IC) component that comprises two independent voltage comparators, designed for use in a wide range of applications. It is a high-gain, differential input, low-power device that can operate from a single power supply.
Here are the key features of the LM293DG:
1. Dual Comparators: The IC consists of two independent voltage comparators, denoted as Comparator 1 and Comparator 2. Each comparator contains a non-inverting input (labeled as V+), an inverting input (labeled as V-), and an output.
2. Wide Input Voltage Range: The LM293DG can accept input voltages ranging from V- (typically the ground) to V+ (power supply voltage), ensuring compatibility with various signal sources.
3. Common Mode Input Voltage Range: The IC has a common mode input voltage range that extends from the negative supply voltage (V-) to within 1.5V of the positive supply voltage (V+), allowing flexibility in input configuration.
4. Low Input Bias Current: The LM293DG exhibits low input bias currents, typically in the range of a few nanoamperes. This characteristic minimizes the impact of input current on the compared signals.
5. Low Power Consumption: The IC has a low power consumption, making it suitable for battery-powered and low-power applications. It can operate over a wide supply voltage range, typically from 2V to 36V
