LT1190CJ8

Video Amps And Modules Overview

The LT1190CJ8 is a high-speed video operational amplifier manufactured by Analog Devices Inc. in an 8-lead ceramic dual in-line package (CERDIP). 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 of supply current. It provides a guaranteed output current of -50mA and includes a shutdown feature accessible via Pin 5 to reduce power dissipation.

Video Amps And Modules Procurement Notes

Verify component authenticity through authorized distributors as the LT1190CJ8 is listed as obsolete. Confirm that the CERDIP package matches design requirements since plastic alternatives like PDIP or SOIC are available. Check for RoHS compliance status given the age of the part number and potential manufacturing changes over time.

Video Amps And Modules Selection Notes

Select this component when high-speed video signal conditioning is required alongside low cost constraints. Consider the shutdown pin functionality if power management or multiplexing multiple signals onto a common line is necessary. Ensure the application can accommodate the specific input offset voltage and bias current characteristics typical of this amplifier family.

Video Amps And Modules Part Context

The LT1190 series represents a family of video operational amplifiers designed for wideband signal processing. While the CJ8 variant utilizes a hermetic ceramic package, other versions exist in plastic DIP and SOIC formats. These amplifiers share core electrical specifications but differ in thermal handling and physical footprint, catering to diverse industrial and commercial packaging needs.

Video Amps And Modules FAQ

How does the shutdown feature function?

Connecting Pin 5 to the negative supply voltage shuts off the output, reducing power dissipation to approximately 15mW while maintaining a high impedance state.

What is the maximum supply voltage range?

The total supply voltage from V+ to V- must not exceed 18V according to absolute maximum ratings.
