The HA-5020 is a wide bandwidth, high slew rate amplifieropTImized for video applicaTIons and gains between 1 and10. Manufactured on Intersil’s Reduced FeatureComplementary Bipolar DI process, this amplifier usescurrent mode feedback to maintain higher bandwidth at agiven gain than convenTIonal voltage feedback amplifiers.Since it is a closed loop device, the HA-5020 offers bettergain accuracy and lower distorTIon than open loop buffers.The HA-5020 features low differential gain and phase andwill drive two double terminated 75Ω coax cables to videolevels with low distortion. Adding a gain flatnessperformance of 0.1dB makes this amplifier ideal fordemanding video applications. The bandwidth and slew rateof the HA-5020 are relatively independent of closed loopgain. The 100MHz unity gain bandwidth only decreases to60MHz at a gain of 10. The HA-5020 used in place of aconventional op amp will yield a significant improvement inthe speed power product. To further reduce power, HA-5020has a disable function which significantly reduces supplycurrent, while forcing the output to a true high impedancestate. This allows the outputs of multiple amplifiers to bewire-OR’d into multiplexer configurations. The device alsoincludes output short circuit protection and output offsetvoltage adjustment.For multi channel versions of the HA-5020 see the HA5022dual with disable, HA5023 dual, HA5013 triple and HA5024quad with disable op amp data sheets.
