Overview
The LHV870LC/NOPB is a general-purpose operational amplifier manufactured by National Semiconductor. It features one circuit with a gain-bandwidth product of 55 MHz and a maximum input offset voltage of 2000 µV. The device operates from -40°C to 85°C and draws 5 mA of supply current. It is housed in a surface-mount 10-UQFN (2.6x2.6) package.
Feature Summary
- General-purpose operational amplifier design
- High-speed performance with 55 MHz gain-bandwidth product
- Low input offset voltage specification
Applications
- Signal conditioning circuits
- Buffer amplification stages
- Instrumentation applications
Procurement Notes
Verify the manufacturer designation, as this component is associated with both National Semiconductor and Texas Instruments due to corporate acquisition history. Confirm the specific package type matches the 10-UQFN (2.6x2.6) footprint required for your PCB layout. Ensure the operating temperature range of -40°C to 85°C meets your environmental requirements before finalizing procurement.
Selection Notes
Select this component when a standard operational amplifier with moderate speed and low offset voltage is required. The 55 MHz bandwidth suits applications needing faster response than standard audio op-amps but not requiring ultra-high-speed RF performance. The bipolar technology offers specific noise characteristics suitable for precision analog signal processing tasks.
Part Context
This part belongs to the family of linear integrated circuits designed for general analog signal processing. National Semiconductor was acquired by Texas Instruments, which continues to support and list these legacy parts. The NOPB suffix indicates compliance with RoHS standards, ensuring the component is lead-free and environmentally compliant for modern manufacturing processes.
Replacement Considerations
Direct substitutes may include other general-purpose op-amps with similar 55 MHz bandwidth and 2000 µV offset voltage specifications. Verify pin compatibility for the 10-UQFN package if considering alternative manufacturers. Cross-reference datasheets to ensure supply current and operating temperature ranges align with system constraints.
