General Description
The GS863X have a high gain-bandwidth product of 6MHz, a slew rate of 4.2V/µs, and a quiescent current of 470µA per
amplifier at 5V. The GS863X are designed to provide optimal performance in low voltage and low noise systems. They provide
rail-to-rail output swing into heavy loads. The input common mode voltage range includes ground, and the maximum input
operating range is from 2.1V to 5.5V. The GS8631 single is available in Green SC70-5, SOT23-5 and SOP-8 packages. The
GS8631NH single is available in Green SC70-6 and SOT23-6 packages. The GS8631NL single is available in Green SC70-6
and SOT23-6 packages. The GS8632 dual is available in Green SOP-8 and MSOP-8 packages. The GS8634 Quad is
available in Green SOP-14 and TSSOP-14 packages.

Note:
Stress greater than those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a
stress rating only and functional operation of the device at these or any other conditions outside those indicated in the operational
sections of this specification are not implied. Exposure to absolute maximum rating conditions for extended periods may affect
reliability.
