Overview
The LM2485NA/NOPB is a video amplifier module manufactured by Texas Instruments. It integrates triple bias clamp circuits and a CRT driver within a single package. The device is designed for high-speed video signal processing applications requiring precise voltage clamping and drive capabilities. It operates with a supply voltage range of 8 V to 36 V and draws a typical operating current of 2.4 mA. The component is housed in a 24-pin PDIP package and supports through-hole mounting. It functions as a high-gain amplifier suitable for analog video signal conditioning.
Feature Summary
- Integrates triple bias clamp functionality for accurate DC restoration in video signals
- Includes an integrated CRT driver stage for direct display interface capability
- Operates on a wide single-supply voltage range from 8 V to 36 V
- Provides high gain amplification suitable for precision video signal processing
Applications
- Video signal conditioning and processing circuits
- CRT display driver interfaces
- Analog video equipment requiring DC restoration
- Professional broadcast video hardware
Procurement Notes
Verify the specific suffix NA against the official Texas Instruments datasheet to confirm pinout and electrical characteristics match your design requirements. Ensure the 24-DIP package dimensions align with your PCB footprint. Confirm RoHS compliance status via the manufacturer's documentation before finalizing procurement decisions.
Selection Notes
Select this component when designing video systems that require integrated bias clamping and CRT driving capabilities without external discrete components. Consider the 8 V to 36 V supply range and 2.4 mA quiescent current during power budget calculations. Evaluate the 24-DIP package constraints for mechanical integration in through-hole assembly processes.
Part Context
This part belongs to the Texas Instruments video amplifier and module family, specifically categorized under PMIC and signal chain components. It serves specialized roles in analog video processing where dedicated bias clamping and display driving are necessary. The NOPB suffix indicates lead-free and RoHS-compliant manufacturing standards consistent with modern electronic component regulations.
Replacement Considerations
Consult the official Texas Instruments replacement matrix or equivalent product selection guide for verified cross-references. Do not assume functional compatibility with other video amplifiers without verifying pinouts, electrical specifications, and thermal characteristics against the original datasheet.
