LM2903YQ3T  

Linear Comparators

The LM2903YQ3T is a quad comparator manufactured by STMicroelectronics. It is a monolithic integrated circuit that consists of four independent voltage comparators. The comparators have a wide range of operating voltages and are designed to provide high accuracy and low power consumption.

Description:

The LM2903YQ3T is a 14-pin DIP (Dual In-line Package) or SOIC (Small Outline Integrated Circuit) package. It has a supply voltage range of 2V to 36V and operates over a temperature range of -40°C to +125°C. The comparators have an input common-mode voltage range that extends beyond the supply rails, allowing them to accept inputs that are below or above the supply voltage.

Features:

1. Quad comparators in a single package
2. Wide supply voltage range (2V to 36V)
3. High accuracy and low power consumption
4. Input common-mode voltage range extends beyond the supply rails
5. Short-circuit protection for the output
6. Open-collector outputs with pull-up resistors
7. Available in both DIP and SOIC packages

Applications:

The LM2903YQ3T has a wide range of applications due to its versatility and high accuracy. Some of the common applications include:

1. Signal conditioning and amplification
2. Voltage level detection and monitoring
3. Pulse generation and shaping
4. A/D and D/A converter interfaces
5. Temperature control and monitoring
6. Motor control and speed regulation
7. Battery monitoring and management
8. Strain gauge signal conditioning
9. Audio and video signal processing
10. Medical equipment and instrumentation

In summary, the LM2903YQ3T is a versatile and accurate quad comparator that can be used in various applications where voltage level detection, signal conditioning, and pulse generation are required.
