ESD SENSITIVITY CAUTION
This integrated circuit can be damaged if ESD protections are
not considered carefully. SGMICRO recommends that all
integrated circuits be handled with appropriate precautions.
Failureto observe proper handlingand installation procedures
can cause damage. ESD damage can range from subtle
performance degradation tocomplete device failure. Precision
integrated circuits may be more susceptible to damage
because even small parametric changes could cause the
device not to meet the published specifications.

High Speed, Ultra-Low Noise,
SGM8262-2
Rail-to-Rail Output, High Output Current Amplifier
APPLICATION INFORMATION
The SGM8262-2 is a dual, low noise, high speed
operational amplifier with voltage feedback function.
The output swing is rail-to-rail with heavy loads. The
SGM8262-2 is optimized for high voltage operation
from ±2.25V to ±18V dual supplies.
Layout
A good PCB layout is important for the performance of
SGM8262-2 in high speed applications in order to prevent
the parasitic effects from the board. The PCB should
have a low impedance loop (or ground) to the power
supply. Removing the GND planes for all of the layers
of the PCB board can simply reduce the stray
capacitors. Also, the PCB traces should be placed as
short as possible in order to reduce parasitic
inductance and capacitance. The resistors or loads
should be placed as close as possible to the terminals
of the SGM8262-2. The input traces of the SGM8262-2
should be placed away from the output trace to
minimize coupling (crosstalk).
Power Supply and Decoupling
The supported voltage of the power supply for
SGM8262-2 is from ±2.25V to ±18V. Also, the customer
should ensure that the source of the power supply is
low noise and well-regulated. The power supply should
be decoupled suitably. The power supply ripple and
power dissipation can be decreased dramatically by
using low ESR capacitor. The multilayer ceramic
capacitors (MLCCs) are good choices for decoupling. A
0.1μF MLCC capacitor should be placed as close as
possible (0.125 inches) to the power supply pin of the
SGM8262-2. For decoupling the low-frequency signals,
10μF to 22μF tantalum capacitors should be taken into
account so that it can convey the current for large and
fast signal changes.
If the SGM8262-2 is used for differential driver, the
customers should guarantee the symmetrical layout to
obtain better output performance. If the trace for the
differential signal is long, please make sure that place
the two differential traces as close as possible, or twist
them together in order to reduce the inductive loop. The
above method can enhance the anti-interference ability
for RF signal by reducing the radiated energy. It is
recommended to use strip line for the signal trace
which is longer than 1 inch.
