LT1187CS8#TRPBF

Video Amps And Modules Overview

The LT1187CS8#TRPBF is a low power video difference amplifier from Analog Devices, housed in an 8-lead plastic SO package. It operates on ±5V or single 5V supplies with a supply current of 13mA. Key electrical parameters include a slew rate of 165V/µs, a small-signal bandwidth of 50MHz at AV = ±2, and an output current capability of ±20mA. The device features a shutdown function that reduces power dissipation to 15mW.

Video Amps And Modules Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing this component. Confirm the CS8 designation corresponds to the 8-lead plastic SO package variant. Ensure the temperature grade matches the required operational range for your design environment. Cross-reference the manufacturer part number with official distributor catalogs to confirm availability status.

Video Amps And Modules Selection Notes

Select the LT1187CS8#TRPBF for applications requiring high-speed differential-to-single-ended conversion with low power consumption. This component is suitable for designs needing a 165V/µs slew rate and 50MHz bandwidth. Consider the shutdown pin functionality if multiplexing signals is required. Verify that the external resistor network supports the desired closed-loop gain configuration.

Video Amps And Modules Part Context

This component belongs to the LT1187 family of low power video difference amplifiers. It serves as a lower power alternative to the LT1193 while maintaining pin compatibility. The series includes variants optimized for different gain ranges, such as the LT1189 for higher gains. These devices are designed for video signal processing and cable driver applications.

Video Amps And Modules FAQ

How does the LT1187 handle input signals exceeding its standard linear range?

The standard maximum input differential signal is approximately ±0.38V. To handle larger signals up to 1.5VP-P, Pin 3 can be grounded and the input applied between Pins 1 and 2, though this may cause the amplifier to go open loop.

What is the purpose of the feedback correction mechanism in the LT1187?

Feedback is applied to Pin 8 to force balance in the input stages by introducing an input offset voltage, which helps minimize the total output offset voltage contributed by both input pairs.
