The AT8091/1N(single), AT8092/2N(dual), AT8094 (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 commonmode voltage range and output voltage swing, making them easy to use on single supplies as low as 2.5V. Despite being low cost, the AT809X 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 AT809X series is low distortion and fast settling make it ideal for buffering high speed A/D or D/A converters. The AT8091/2N has a power-down disable feature that reduces the supply current to 75μA. These features make the AT8091/2N ideal for portable and battery-powered applications where size and power are critical. All are specified over the extended −40°C to +125°C temperature range.
