LT1191CN8#PBF

Video Amps And Modules Overview

The LT1191CN8#PBF is an ultrahigh speed video operational amplifier manufactured by Analog Devices Inc. It features a gain bandwidth product of 90MHz and a slew rate of 450V/µs. The device operates on a single 5V supply or dual supplies ranging from ±2.375V to ±8V, with a typical supply current of 32mA. 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 Feature Summary

• Ultrahigh speed performance with 90MHz unity-gain bandwidth and 450V/µs slew rate
• Integrated output shutdown capability for power conservation and multiplexing applications
• Optimized for driving heavy loads with high open-loop gain exceeding 90dB
• Capable of full-power operation at 20MHz with 7V peak-to-peak swing

Video Amps And Modules Applications

• Video cable drivers
• Video signal processing
• Fast integrators
• Pulse amplifiers
• D/A current to voltage conversion

Video Amps And Modules Procurement Notes

Verify the specific suffix CN8 corresponds to the 8-lead PDIP package before procurement. Confirm that the #PBF designation ensures compliance with RoHS standards. Check the manufacturer's latest documentation for obsolescence status, as older revisions may be discontinued. Ensure the application environment remains within the specified commercial temperature range of 0°C to 70°C for this variant.

Video Amps And Modules Selection Notes

Select the LT1191CN8#PBF when high-speed signal conditioning requires a true operational amplifier architecture rather than a dedicated video buffer. Consider its ability to drive low impedance loads like 75Ω cables directly. Evaluate the shutdown pin utility if system power management or channel multiplexing is required. Verify that the input common mode voltage range aligns with the signal source requirements.

Video Amps And Modules Part Context

This component belongs to the LT1191 family of ultrahigh speed operational amplifiers designed for video applications. It is available in multiple packages including SOIC and CERDIP. The CN8 variant specifically denotes the plastic dual in-line package suitable through-hole mounting. Related parts include the LT1363 and LT1813 for different speed and power profiles.
