Présentation
Description
Key characteristics include a low input offset voltage, low input bias current, and a common-mode input voltage range that extends to the negative rail. These features make it ideal for applications requiring precise voltage monitoring, such as battery management systems, sensor interfaces, and threshold detectors. The IC is packaged in a TSSOP (Thin Shrink Small Outline Package) format, offering a compact solution for space-constrained designs. Its robust performance over a wide temperature range (typically -40°C to +125°C) ensures reliability in various industrial and consumer electronics applications.
Equivalent
1. LM339 series by various manufacturers like Texas Instruments, STMicroelectronics, and ON Semiconductor.
2. TLV1704 series by Texas Instruments.
3. MCP6544 series by Microchip Technology.
4. NCS2200 series by ON Semiconductor.
These products offer similar performance characteristics, but always check the datasheets for specific parameters to ensure compatibility with your application.
Features
1. Low Supply Voltage: Operates over a wide range of supply voltages from 2.7V to 5.5V, making it suitable for battery-powered applications.
2. Low Current Consumption: Designed for low power consumption with a typical quiescent current of 10 µA per comparator, which is beneficial for energy-efficient applications.
3. Rail-to-Rail Inputs: Allows the input voltage range to extend beyond both supply rails, enhancing flexibility in input signal handling.
4. Output Characteristics: Open-drain output stage allows for wired-OR configurations and interfacing with other logic levels.
5. Fast Response Time: Offers a quick response with a typical propagation delay of 300 ns, suitable for high-speed signal processing.
6. Small Package: Available in a compact VSSOP (Mini SO-8) package, saving space on PCBs.
These characteristics make the LMV339IRUCR ideal for low-power, portable, and space-constrained applications requiring reliable low-voltage comparison.
Pinout
1. VCC (Positive Supply Voltage)
2. GND (Ground)
3. Four inverting inputs (one for each comparator)
4. Four non-inverting inputs (one for each comparator)
5. Four output pins (one for each comparator)
This configuration allows the LMV339 to perform four independent voltage comparisons. Note that the specific pin assignment can vary based on the package type, so it is always best to refer to the datasheet for precise details.
