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.
