General Description
The GS8091/1N(single), GS8092/2N(dual),
GS8094(quad)
are rail-to-rail output voltage feedback amplifiers offering ease
of use and low cost. They have bandwidth and slew rate typically found in current feedback amplifiers. All have a wide
input common-mode voltage range and output voltage swing, making them easy to use on single supplies as low as 2.5V.
Despite being low cost, the GS8091 series provide excellent overall performance. They offer wide bandwidth to 350MHz
(G = +1) along with 0.1dB flatness out to 58MHz (G = +2) and offer a typical low power of 4.2mA/amplifier.
The GS8091 series is low distortion and fast settling make it ideal for buffering high speed A/D or D/A converters. The
GS8091/2N has a power-down disable feature that reduces the supply current to 75µA. These features make the
GS8091/2N ideal for portable and battery-powered applications where size and power are critical. All are specified over
