SGM8051/2/4
SGM8053/5
PRODUCT DESCRIPTION
The SGM8051/3 (single), SGM8052/5 (dual), SGM8054
(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 SGM8051 series provide
excellent overall performance. They offer wide
bandwidth to 250 MHz (G = +1) along with 0.1 dB flatness
out to 37 MHz（G = +2）and offer a typical low power of
2.3 mA/amplifier.
The SGM8051 series is low distortion and fast settling
make it ideal for buffering high speed A/D or D/A
converters. The SGM8053/5 has a power-down disable
feature that reduces the supply current to 75 µA. These
features make the SGM8053/5 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.

NOTES
1. Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may
affect device reliability.
CAUTION
This integrated circuit can be damaged by ESD.
Shengbang Micro-electronics recommends that all
integrated circuits be handled with appropriate
precautions. Failure to observe proper handling and
installation procedures can cause damage.
ESD damage can range from subtle performance
degradation to complete device failure. Precision
integrated circuits may be more susceptible to
damage because very small parametric changes
could cause the device not to meet its published
specifications.
