HA-5020/883  
100MHz Current Feedback  
Video Amplifier with Disable  
January 1996  
Features  
Description  
• This Circuit is Processed in Accordance to MIL-STD- The HA-5020/883 is a wide bandwidth, high slew rate  
883 and is Fully Conformant Under the Provisions of amplifier optimized for video applications and gains between  
Paragraph 1.2.1.  
1 and 10. Manufactured on Intersil’s Reduced Feature  
Complementary Bipolar DI process, this amplifier uses cur-  
rent mode feedback to maintain higher bandwidth at a given  
• Wide Unity Gain Bandwidth . . . . . . . . . . 105MHz (Min)  
• Slew Rate . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 800V/µs gain than conventional voltage feedback amplifiers. Since it  
is a closed loop device, the HA-5020/883 offers better gain  
accuracy and lower distortion than open loop buffers.  
• Output Current . . . . . . . . . . . . . . . . . . . . . . ±30mA (Min)  
• Drives 3.5V into 75Ω  
The HA-5020/883 features low differential gain and phase and  
will drive two double terminated 75Ω coax cables to video  
levels with low distortion. Adding a gain flatness performance  
of 0.1dB makes this amplifier ideal for demanding video  
applications. The bandwidth and slew rate of the HA-5020/  
883 are relatively independent of closed loop gain. The  
105MHz unity gain bandwidth only decreases to 77MHz at a  
gain of 10. The HA-5020/883 used in place of a conventional  
op amp will yield a significant improvement in the speed  
power product. To further reduce power, the HA-5020/883 has  
a disable function which significantly reduces supply current,  
while forcing the output to a true high impedance state. This  
allows the outputs of multiple amplifiers to be wire-OR’d into  
multiplexer configurations. The device also includes output  
short circuit protection and output offset voltage adjustment.  
• Differential Gain . . . . . . . . . . . . . . . . . . . . . . . . . . 0.025%  
• Differential Phase. . . . . . . . . . . . . . . . . . . . . . .0.025 Deg  
• Low Input Noise Voltage . . . . . . . . . . . . . . . . 4.5nV/√Hz  
• Low Supply Current. . . . . . . . . . . . . . . . . . . 10mA (Max)  
• Wide Supply Range . . . . . . . . . . . . . . . . . . . ±5V to ±15V  
• Output Enable/Disable  
• High Performance Replacement for EL2020/883  
Applications  
• Unity Gain Video/Wideband Buffer  
• Video Gain Block  
The HA-5020/883 offers significant enhancements over  
competing amplifiers, such as the EL2020. Improvements  
include unity gain bandwidth, slew rate, video performance,  
lower supply current, and superior DC specifications.  
• Video Distribution Amp/Coax Cable Driver  
• Flash A/D Driver  
• Waveform Generator Output Driver  
• Current to Voltage Converter; D/A Output Buffer  
• Radar Systems
