The HA4600 is a very wide bandwidth, unity gain buffer ideal for professional video switching, HDTV, computer monitor routing, and other high performance applications. The circuit features very low power dissipation (105mW Enabled, 1mW Disabled), excellent differential gain and phase, and very high off isolation. When disabled, the output is switched to a high impedance state, making the HA4600 ideal for routing matrix equipment and video multiplexers. The HA4600 also features fast switching and symmetric slew rates. A typical application for the HA4600 is interfacing Intersil’s wide range of video crosspoint switches. For applications requiring a tally output (enable indicator), please refer to the HA4201 data sheet.

The HA-5002 is a monolithic, wideband, high slew rate, high output current, buffer amplifier. Utilizing the advantages of the Intersil D. I. technologies, the HA-5002 current buffer offers 1300V/μs slew rate with 110MHz of bandwidth. The ±200mA output current capability is enhanced by a 3Ω output impedance. The monolithic HA-5002 will replace the hybrid LH0002 with corresponding performance increases. These characteristics range from the 3000kΩ input impedance to the increased output voltage swing. Monolithic design technologies have allowed a more precise buffer to be developed with more than an order of magnitude smaller gain error. The HA-5002 will provide many present hybrid users with a higher degree of reliability and at the same time increase overall circuit performance. For the military grade product, refer to the HA-5002/883 datasheet.

The HA5023 is a wide bandwidth high slew rate dual amplifier optimized for video applications and gains between 1 and 10. It is a current feedback amplifier and thus yields less bandwidth degradation at high closed loop gains than voltage feedback amplifiers. The low differential gain and phase, 0. 1dB gain flatness, and ability to drive two back terminated 75Ω cables, make this amplifier ideal for demanding video applications. The current feedback design allows the user to take advantage of the amplifier's bandwidth dependency on the feedback resistor. By reducing RF, the bandwidth can be increased to compensate for decreases at higher closed loop gains or heavy output loads. The performance of the HA5023 is very similar to the popular Intersil HA-5020.

The HA-4900 series are monolithic, quad, precision comparators offering fast response time, low offset voltage, low offset current and virtually no channel-to-channel crosstalk for applications requiring accurate, high speed, signal level detection. These comparators can sense signals at ground level while being operated from either a single +5V supply (digital systems) or from dual supplies (analog networks) up to ±15V. The HA-4900 series contains a unique current driven output stage which can be connected to logic system supplies (VLOGIC+ and VLOGIC-) to make the output levels directly compatible (no external components needed) with any standard logic or special system logic levels. In combination analog/digital systems, the design employed in the HA-4900 series input and output stages prevents troublesome ground coupling of signals between analog and digital portions of the system. These comparators' combination of features make them ideal components for signal detection and processing in data acquisition systems, test equipment and microprocessor/analog signal interface networks.
