LT1190CS8#PBF

Video Amps And Modules Overview

The LT1190CS8#PBF is a high-speed video operational amplifier manufactured by Analog Devices Inc. in an 8-lead SOIC package. It features a gain bandwidth product of 50MHz and a slew rate of 450V/µs. The device operates on single 5V or dual ±5V supplies, drawing 32mA supply current. Key electrical parameters include a settling time of 140ns to 0.1%, differential gain error of 0.1%, and differential phase error of 0.06°. It provides -50mA output current and includes a shutdown feature via Pin 5.

Video Amps And Modules Procurement Notes

Verify the specific suffix 'S8' confirms the 8-lead plastic small outline package type. Confirm RoHS compliance status as indicated in official documentation. Ensure the operating temperature range matches the 'C' grade specification (0°C to 70°C) required for the intended environment. Cross-reference the manufacturer part number with authorized distributors to ensure authenticity.

Video Amps And Modules Selection Notes

Select this component when a unity-gain stable video amplifier with high slew rate is required. It is suitable for applications needing single 5V operation or dual ±5V supplies. Consider the shutdown capability if power conservation or multiplexing onto common cables is necessary. Evaluate the 140ns settling time against system timing requirements.

Video Amps And Modules Part Context

This part belongs to the LT1190 series of video operational amplifiers designed for high-speed signal processing. It is distinct from general-purpose op-amps due to its optimized performance for video frequencies and cable driving capabilities. The S8 suffix denotes the surface-mount SOIC package variant within the broader LT1190 family.

Video Amps And Modules FAQ

How does the shutdown feature function?

Taking Pin 5 to V– shuts off the output and reduces power dissipation to 15mW while maintaining a true high impedance output state.

What is the recommended cable termination method?

Double termination using 75Ω resistors in series with the output and 75Ω to ground at the receiving end is preferred to absorb reflected energy.
