Description


The GS9028 is a second generation bipolar integrated circuit designed to drive two 75ohm co-axial cables.

The GS9028 features two complementary outputs whose amplitude is controlled within ± 7%. The output signal levels of GS9028 are also adjustable from as low as 50mV to as high as 1000mV with little change in other performance parameters. The output amplitude of the output stage is varied by adjusting the RSET resistor value.

The GS9028 consumes 45% less system power than the GS9008 and does not require external pulldown resistors resulting in a smaller PCB footprint. Operational with input amplitudes as low as 80mV, the GS9028 is a robust serial interface device.

The GS9028 is packaged in an 8 pin SOIC and operates from a single +5 or -5 volt supply.
