NTE927D & NTE927SM Integrated Circuit Differential Video Amplifier Description: The NTE927D and NTE927SM are twostage, differential input, differential output, wideband video amplifiers. The use of internal seriesshunt feedback gives wide band bandwidth with low phase dis- tortion and high gain stability. Emitterfollower outputs provide a high current drive, low impedance capability. Its 120MHz bandwidth and selectable gains of 10, 100, and 400, without need for frequen- cy compensation, make it a very useful circuit for memory element drivers, pulse amplifiers, and wide band gain stages. Features: 120MHz Bandwidth 250k Input Resistance No Frequency Compensation Required Selectable Gains of 10, 100 and 400 High Common Mode Rejection Ratio at High Frequencies Applications: Magnetic Tape Systems Disk File Memories Thin and Thick Film Memories Woven and Plated Wire Memories Wide Band Video Amplifiers Absolute Maximum Ratings: Differential Input Voltage . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 5V Common Mode Input Voltage . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 6V Supply Voltage, V . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 8V CC Output Current, I . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 10mA O Power Dissipation (Note 1), P . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 500mW D Junction Temperature, T . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . +100C J Storage Temperature Range, T . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 65 to +150C stg Operating Temperature Range, T . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 0 to +70C opr Lead Temperature (Soldering, 10sec), T . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . +260C L Note 1.
