DESCRIPTION

The GB4550 and GB4550A are high performance monolithic video buffer/clamps made on Gennums LSI process. They feature a wideband differential amplifier that can be configured as a gain stage. The output signal voltage is limited to +2V above the clamp level in order to prevent damage to crosspoints connected to the output.

FEATURES

• adjustable clamp level from -5.5 V to +5.5 V at ±10 V supplies.

• ultra low differential gain (0.02 typ.) and differential phase (0.03° typ.)

• wideband unity gain: GB4550 ±0.2 dB at 25 MHz GB4550A ±0.1 dB at 25 MHz

• both drive 150pF loads at full power, flat to 10 MHz.

• GB4550A — tight delay spread of ±0.15°at colorburst.

• convenient 8 pin SIP packaging.

• both can be configured as a gain stage with reduced bandwidth.
