PRODUCT DESCRIPTION
The SGM8091/8093(single), SGM8092 (dual), SGM8094
(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 2.5 V.
Despite being low cost, the SGM8091 series provide
excellent overall performance. They offer wide
bandwidth to 350 MHz (G = +1) along with 0.1 dB
flatness out to 125 MHz (G = +1) and offer a typical
low power of 4.3 mA/amplifier.
The SGM8091 series are low distortion and fast
settling make them ideal for buffering high speed A/D
or D/A converters. The SGM8093 has a power-down
disable feature that reduces the supply current to
75µA. These features make the SGM8093 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.
