HA-5020_883

The HA-5020/883 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-5020/883 offers better gain accuracy and lower distortion than open loop buffers.

The HA-5020/883 features low differential gain and phase and will drive two double terminated 75 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.

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.
