LM2202N - 230 MHz Video Amplifier System | Texas Instruments
料号： LM2202N ✗ 停产LM2202N 概述
A video amplifier system is an integrated circuit that conditions analog video signals so they can be reproduced reliably by a display or monitor. Its position in the signal chain is between the source of a composite or RGB video waveform and the display driver circuitry. The broad product category can be described as video amplifier, then analog video processing IC, then signal-conditioning integrated circuit, and finally semiconductor.
The LM2202N is identified as a 230 MHz video amplifier system in a 20-PDIP package. Its key documented characteristics include video-amplifier functionality, a bandwidth designation of 230 MHz, general-purpose classification, through-hole construction, and a commercial-extended temperature grade. These attributes place it in applications requiring high-speed analog video amplification rather than low-frequency audio amplification or general-purpose logic.
The LM2202N was developed for high-resolution monochrome and RGB color monitor systems. This application focus distinguishes it from general-purpose op-amp-based video circuits: the device is organized as a complete video amplifier system rather than as a general comparator or precision analog amplifier. At 230 MHz, it is suited to signal paths where wide video bandwidth is an important consideration.
Typical uses include RGB monitor input stages, monochrome display channels, video test equipment, and legacy display electronics in which an analog video signal must be amplified before reaching the next processing stage. Component selection should account for the 20-pin DIP footprint, required bypass and termination components, and the signal amplitude expected at the amplifier input and output.
Use the manufacturer pin-description table when assigning PCB connections, and follow the application circuit in the manufacturer datasheet for component values and signal termination. Because the part is a through-hole 20-pin DIP, board layout should preserve the package outline, pin numbering, and adequate clearance around adjacent traces. Confirm operating temperature and supply requirements against the datasheet before production use.
This page organizes the LM2202N identity, package information, intended applications, sourcing guidance, and design cautions into one engineering reference. It also separates established device facts from parameters that require confirmation from the controlling manufacturer documentation, helping designers evaluate the IC without confusing it with unrelated video processors, monitors, or display-driver components.

典型应用
LM2202N 适用于 6 应用s: RGB Color Monitor Signal Conditioning, High-Resolution Monochrome Display, Legacy Video Test Equipment, Analog Video Interface Module, Video Distribution Card, Industrial Monitor Control Electronics.
RGB Color Monitor Signal Conditioning
The LM2202N is designed for high-resolution RGB color monitor applications, where its 230 MHz video amplifier system rating provides the bandwidth appropriate to wideband analog display signals. It can serve as a central amplification stage when the RGB channels require consistent signal conditioning before reaching subsequent display circuitry. The 20-pin DIP package also suits legacy monitor boards that use through-hole construction. According to the manufacturer datasheet, the original application circuit should define the gain, termination, compensation, and bypass arrangements. Retaining that topology minimizes the risk of changing edge response or drive level while repairing or maintaining established monitor hardware.
推荐
High-Resolution Monochrome Display
The LM2202N is intended for high-resolution monochrome monitor systems and is specified as a 230 MHz video amplifier system in a 20-pin through-hole DIP package. This makes it relevant to legacy display equipment that conditions a high-speed monochrome video waveform before the monitor's deflection or driver circuitry. The broad bandwidth designation supports wideband video applications, but system performance still depends on the source impedance, termination, and PCB layout. According to the manufacturer datasheet, use the documented application circuit and pin descriptions when adapting the device to a display channel, especially where component tolerances and compensation values affect image geometry.
推荐
Legacy Video Test Equipment
The LM2202N can serve in analog video test and measurement equipment that needs a 230 MHz amplification stage rather than a general-purpose precision amplifier. Its video amplifier system architecture and 20-pin DIP package are relevant to vintage test fixtures, signal-conditioning panels, and monitor-service equipment where the original board area and through-hole footprint are fixed. According to the manufacturer datasheet, the device should be configured using the documented gain and compensation arrangement. Before inserting it into test equipment, confirm signal amplitude, termination, supply requirements, and allowable temperature conditions so the amplifier remains within its specified operating envelope.
推荐
Analog Video Interface Module
The LM2202N is applicable to an analog video interface module that receives a composite or component video waveform and conditions it for downstream processing. Its 230 MHz video amplifier system designation is well matched to high-resolution display signals, while the 20-pin through-hole package allows straightforward integration into a legacy through-hole module. According to the manufacturer datasheet, the exact input and output levels must remain within the circuit limits, and the recommended external compensation and bypass components should be retained. This makes the device useful for repair-oriented interface modules that must preserve established monitor behavior.
推荐
Video Distribution Card
The LM2202N can be evaluated for a video distribution card that must preserve wideband analog signal content across one or more display outputs. The 230 MHz video amplifier system rating provides the relevant bandwidth class for high-resolution monochrome or RGB signals, and the 20-pin DIP package is convenient for repairable laboratory or industrial cards. According to the manufacturer datasheet, output loading and termination must be checked against the recommended circuit rather than assumed. Grounding, bypass placement, and signal routing should follow the manufacturer application guidance to avoid introducing instability or reflections into the amplified video path.
推荐
Industrial Monitor Control Electronics
The LM2202N is suitable for service and modernization work involving industrial monitor electronics that use a 230 MHz video amplifier system. Its commercial-extended temperature grade and high-resolution video application focus align with display equipment requiring analog signal amplification under controlled industrial conditions. The 20-pin through-hole DIP construction also allows use in repair boards with conventional through-hole footprints. According to the manufacturer datasheet, verify the supply, gain, and temperature limits before deployment. Maintaining the documented feedback and compensation topology is the safest approach when replacing the original device in equipment where display geometry and signal fidelity have already been characterized.

设计说明
Create the PCB footprint from the controlled 20-pin DIP package drawing rather than from a generic DIP footprint. Confirm pin-1 orientation, row spacing, drill diameter, and body width before release. Because the LM2202N is intended for high-frequency video amplification, route the relevant input, output, feedback, and bypass connections with short traces and a continuous ground reference. Keep the footprint and copper keepouts compatible with the physical legacy assembly when repairing an existing monitor board.
Follow the manufacturer application circuit for termination, feedback, compensation, and bypass components. A 230 MHz video amplifier system can expose board parasitic inductance, excessive loop area, and incorrect source or load impedance. Place input and bypass components close to their associated pins, maintain a low-impedance return path, and avoid routing video signals beside unrelated switching or digital return currents. Recheck edge response and ringing with the complete source, cable, and load arrangement rather than evaluating the IC on an isolated bench fixture.
Do not treat any amplifier with a similar bandwidth rating as a substitute for the LM2202N. A valid comparison must include all 20 pin functions, supply requirements, gain configuration, output loading, and the external compensation network. The device is intended for high-resolution monochrome and RGB monitor circuits, so a generic op amp may alter video gain, stability, or signal polarity. For a legacy board, replacing the device without first comparing the manufacturer application schematic can create fault conditions that are difficult to diagnose.
Use the manufacturer datasheet to establish the required supply voltage, pin connections, and bypass arrangement before energizing the device. Place the specified bypass capacitors near the supply pins and verify that the associated ground return does not share a high-current path with video outputs. Because the exact electrical limits and power-consumption figures are not established by the product listing, use the controlling datasheet for all supply-decoupling and thermal decisions rather than estimating acceptable limits.
合规信息
