250MHz, Rail-to-Rail Output
CMOS Operational Amplifier
FEATURES
PRODUCT DESCRIPTION
• Low Cost
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.
• Rail-to-Rail Output

• Operates on 2.5 V to 5.5 V Supplies
• Input Voltage Range = – 0.2 V to + 3.8 V with VS = 5 V
• Excellent Video Specs (RL = 150Ω, G = +2)
Gain Flatness 0.1dB to 37 MHz
Diff Gain: 0.03 % , Diff Phase: 0.08 degree
• Low Power
2.3 mA/Amplifier Typical Supply Current
75µA/Amplifier when Disabled (SGM8053/5 only)
• Small Packaging
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 75µA. 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.
