LM2416CT - Triple 35MHz Video Amplifier | Texas Instruments
MPN: LM2416CT ✗ اختتامِ زندگیLM2416CT جائزہ
A video amplifier is a specialized amplifier category designed to preserve amplitude and timing relationships across a wide frequency range. Within the signal-chain hierarchy, the LM2416CT combines three video amplifier channels in one package, reducing component count in multi-channel display systems. Its TO-220-11 construction also provides a substantial thermal path compared with small-outline surface-mount packages.
The principal feature of the LM2416CT is its three-channel architecture. Each channel can deliver up to 22 mA, allowing it to support video-cathode drive requirements rather than serving only as a low-current signal-conditioning amplifier. Its 35 MHz bandwidth provides adequate margin for conventional analog CRT video signals while keeping the circuit manageable in legacy display designs.
The LM2416C family is described as a triple 50 MHz CRT driver in the National Semiconductor documentation, while current distributor records identify the LM2416CT as a 35 MHz triple video-amplifier device. These descriptions should be checked against the applicable revision of the manufacturer datasheet when designing new equipment, particularly when bandwidth, gain, settling behavior, or output-stage limits are critical.
Typical applications include CRT monitor video-output boards, multi-channel analog video distribution, laboratory display equipment, and legacy industrial or medical visualization systems. The 11-lead formed TO-220 package makes the LM2416CT most practical in through-hole and repair-oriented assemblies where a robust heat-dissipation path is more important than compactness.
Designers should preserve adequate copper area around the device, provide a clean bypass supply, and follow the manufacturer pin configuration when routing the three channels. Because it is a legacy video-output component, verify connector standards, video bandwidth requirements, thermal conditions, and replacement availability before beginning a new production design.
This page organizes the LM2416CT’s known channel count, bandwidth, current capability, package, sourcing information, comparison candidates, and application guidance into one engineering-focused reference for evaluating legacy analog video drive designs.

CRT Monitor Video Output
The LM2416CT fits CRT monitor video-output boards because it combines three video channels, 35 MHz bandwidth, and 22 mA output-current capability in one 11-terminal TO-220 package. Each channel can be positioned near its corresponding red, green, and blue video path, reducing the number of separate driver packages. The through-hole package also supports substantial copper-area heat dissipation in monitors with long operating intervals. Before implementation, verify the required gain, supply voltage, blanking behavior, and CRT cathode-drive network against the applicable LM2416C documentation.

Analog Video Distribution
The LM2416CT can serve as a three-channel analog video amplifier when a system must distribute separate composite or component-derived signals while preserving adequate rise time. The 35 MHz bandwidth provides useful headroom for conventional analog video content, and the three-channel arrangement allows one package to handle red, green, and blue paths. Its 22 mA output capability supports higher-current drive than a general signal-conditioning op-amp. Layout should minimize loop area between the amplifier outputs and their destination, while preserving the termination values required by the source and load impedances.

Industrial CRT Control Panels
Industrial control panels using CRT displays can benefit from the LM2416CT because three integrated video channels reduce component count compared with three separate amplifier packages. The 35 MHz bandwidth suits standard-resolution analog video, while the 22 mA per-channel output rating provides the drive level associated with CRT cathode circuits. The TO-220-11 package is advantageous in legacy industrial equipment because through-hole construction tolerates repeated servicing and offers a straightforward thermal path. Engineers should nevertheless confirm electrical isolation, grounding, fault behavior, and display-specific timing requirements before adapting the circuit to a modern control system.

Medical Visualization Displays
The LM2416CT can be evaluated for legacy medical visualization systems that retain analog CRT display electronics. Three separately amplified channels support RGB display architectures, and the listed 35 MHz bandwidth is appropriate for many standard analog display formats. Because medical equipment imposes additional documentation, safety, and lifecycle controls, engineers must verify the original circuit’s isolation strategy, fail-safe requirements, and accepted replacement policy. The TO-220 package provides a practical thermal path in serviceable equipment, but production use should begin only after regulatory and quality requirements are independently addressed.

Laboratory Video Test Equipment
The LM2416CT is suitable for experimental video test equipment that needs three medium-bandwidth output channels and moderate current drive. Its 35 MHz bandwidth can support analog test signals within conventional video bandwidth, and the three-channel arrangement simplifies synchronized red, green, and blue output generation. Because the package is through-hole, the device also fits educational and prototype boards where reworkability is valuable. A laboratory designer should measure gain accuracy, output rise time, channel matching, and loading behavior rather than assuming that nominal bandwidth alone guarantees correct performance at the display and cable combination in use.

Legacy Display Repair
The LM2416CT is particularly relevant to repair of legacy CRT equipment because its three channels and 22 mA output-current capability match the broad requirements of a cathode-drive stage. The 11-terminal TO-220 formed package supports direct inspection, socketed adaptation, and conventional through-hole repair techniques. Before installation, compare the replacement’s pin functions, suffix-specific temperature grade, supply requirements, and marking with the failed device. If substituting LM2416T or LM2418T, validate gain, bandwidth, current capability, quiescent behavior, and thermal performance across the intended display load.

ڈیزائن نوٹس
Use the TO-220 thermal path effectively by providing copper area beneath and around the device where the board and mechanical design permit. Estimate the worst-case dissipation from the actual supply voltage, output quiescent current, and output-voltage swing at the maximum expected video load, then confirm that junction temperature remains below the applicable manufacturer limit. The TO-220-11 package improves heat transfer compared with a small-outline package, but it does not replace correct layout and airflow planning.
Route each video channel with short, impedance-controlled paths and keep the output return close to the corresponding signal trace. Place supply-decoupling capacitors at the device power pins and preserve the manufacturer’s recommended grounding arrangement. Because video output stages can carry up to 22 mA per channel, check conductor width, connector current capacity, and return paths to prevent voltage drops that alter video amplitude.
Do not select a replacement from package shape alone. Compare the LM2416CT, LM2416T, or LM2418T pin functions, supply voltage, gain, bandwidth, output-current rating, quiescent current, and temperature grade against the original device. The TO-220-11 outline can contain related parts with different electrical behavior, and the suffix code may identify a meaningful grade or specification difference.
