FEATURES
PRODUCT DESCRIPTION
The SGM8061, SGM8062, SGM8063 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 SGM8061 series provide
excellent overall performance. they offer wide
bandwidth to 500 MHz (G = +1) along with 0.1 dB
flatness out to 130 MHz (G = +1) and offer a typical low
power of 8.2 mA/amplifier.
The SGM8061 series is low distortion and fast settling
make it ideal for buffering high speed A/D or D/A
converters. The SGM8063 has a power-down disable
feature that reduces the supply current to 75µA. These
features make the SGM8063 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.

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.

APPLICATION NOTES

Driving Capacitive Loads
10µF
10µF
0.1µF
The SGM806x family is optimized for bandwidth and speed,
not for driving capacitive loads. Output capacitance will create
a pole in the amplifier’s feedback path, leading to excessive
peaking and potential oscillation. If dealing with load
capacitance is a requirement of the application, the two
strategies to consider are (1) using a small resistor in series
with the amplifier’s output and the load capacitance and (2)
reducing the bandwidth of the amplifier’s feedback loop by
increasing the overall noise gain.

Figure 1 shows a unity gain follower using the series resistor
strategy. The resistor isolates the output from the capacitance
and, more importantly, creates a zero in the feedback path that
compensates for the pole created by the output capacitance.

CLOAD
A ground plane layer is important for high speed circuit design.
The length of the current path speed currents in an inductive
ground return will create an unwanted voltage noise. Broad
ground plane areas will reduce the parasitic inductance.
Figure 1. Series Resistor Isolating Capacitive Load
Input-to-Output Coupling
Power-Supply Bypassing and Layout
To minimize capacitive coupling, the input and output signal
traces should not be parallel. This helps reduce unwanted
positive feedback.
The SGM806x family operates from either a single +2.7V to
+5.5V supply or dual ±1.35V to ±2.75V supplies. For
single-supply operation, bypass the power supply VDD with a
0.1µF ceramic capacitor which should be placed close to the
VDD pin. For dual-supply operation, both the VDD and the VSS
supplies should be bypassed to ground with separate 0.1µF
ceramic capacitors. 2.2µF tantalum capacitor can be added for
better performance.
Good PC board layout techniques optimize performance by
decreasing the amount of stray capacitance at the op amp’s
inputs and output. To decrease stray capacitance, minimize
trace lengths and widths by placing external components as
close to the device as possible. Use surface-mount
components whenever possible.
For the high speed operational amplifier, soldering the part to
the board directly is strongly recommended. Try to keep the
high frequency big current loop area small to minimize the EMI
(electromagnetic interfacing).

The SGM806x can be used in video applications like in Figure 5.
Differential Amplifier
The circuit shown in Figure 3 performs the difference function.
If the resistors ratios are equal ( R4 / R3 = R2 / R1 ), then
VOUT = ( Vp – Vn ) × R2 / R1 + Vref.

Low Pass Active Filter
The low pass filter shown in Figure 4 has a DC gain of ( - R2 / R1 )
and the –3dB corner frequency is 1/2πR2C. Make sure the filter
is within the bandwidth of the amplifier. The Large values of
feedback resistors can couple with parasitic capacitance and
cause undesired effects such as ringing or oscillation in
high-speed amplifiers. Keep resistors value as low as possible
and consistent with output loading consideration.
