LT1191CN8

Video Amps And Modules Overview

The LT1191CN8 is an ultrahigh speed operational amplifier in an 8-lead PDIP package, optimized for –5V and single 5V supply operation. It features a unity-gain-stable bandwidth of 90MHz and a slew rate of 450V/ms. The device delivers high open-loop gain (20V/mV min) and can drive heavy loads to a full-power bandwidth of 20MHz at 7V p-p. Key performance metrics include a settling time of 110ns to 0.1% and differential gain error of 0.07% with a 1k load. A dedicated shutdown pin reduces power dissipation to 15mW when activated.

Video Amps And Modules Procurement Notes

Verify the specific suffix CN8 corresponds to the 8-lead PDIP package before procurement. Confirm that the component meets the commercial temperature range of 0°C to 70°C as specified for the C grade. Ensure design compatibility with the required –5V or single 5V supply rails. Check for any obsolete status notifications from Analog Devices Inc. regarding this specific part number variant.

Video Amps And Modules Selection Notes

Select the LT1191CN8 for applications requiring high speed and accuracy on low voltage supplies. The 8-lead PDIP package is suitable for through-hole mounting. Consider the shutdown functionality if power management or MUX configurations are required. Ensure adequate power supply bypassing, such as a 0.1µF ceramic capacitor, to maintain stability and optimal settling time characteristics during operation.
