The HA-5020 is a wide bandwidth, high slew rate amplifier optimized for video applications and gains between 1 and 10. Manufactured on Intersil’s Reduced Feature Complementary Bipolar DI process, this amplifier uses current mode feedback to maintain higher bandwidth at a given gain than conventional voltage feedback amplifiers. Since it is a closed loop device, the HA-5020 offers better gain accuracy and lower distortion than open loop buffers. The HA-5020 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 are relatively independent of closed loop gain. The 100MHz unity gain bandwidth only decreases to 60MHz at a gain of 10. The HA-5020 used in place of a conventional op amp will yield a significant improvement in the speed power product. To further reduce power, HA-5020 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. For multi channel versions of the HA-5020 see the HA5022 dual with disable, HA5023 dual, HA5013 triple and HA5024 quad with disable op amp data sheets.
