SGM8425/6/8
18MHz, High Voltage, Rail-to-Rail
I/O Operational Amplifiers
GENERAL DESCRIPTION
The SGM8425 (single), SGM8426 (dual) and SGM8428
(quad) are low power, high voltage, rail-to-rail input and
output operational amplifiers. These devices can operate
from ±2.25V to ±15V dual power supplies or from +4.5V
to +30V single supplies.
The SGM8425/6/8 have a bandwidth of 18MHz (-3dB),
while consuming only 1.6mA per amplifier. They also
provide common mode input ability beyond the supply
rails, as well as rail-to-rail output capability. This enables
the SGM8425/6/8 to offer maximum dynamic range at
any supply voltage.
The SGM8425/6/8 also feature fast slewing and settling
times. These features make these amplifiers ideal for use
as voltage reference buffers in Thin Film Transistor
Liquid Crystal Displays (TFT-LCD). Other applications
include battery power, portable devices, and anywhere
low power consumption is important.
The SGM8425 single is available in Green SOT-23-5,
SOIC-8 and MSOP-8 packages. The SGM8426 dual is
available in Green SOIC-8 and MSOP-8 packages. The
SGM8428 quad is available in Green TSSOP-14 and
SOIC-14 packages. They are rated over the -40°C to
+85°C temperature range.

NOTE:
Stresses beyond those listed under “Absolute Maximum
Ratings” may cause permanent damage to the device. These
are stress ratings only, and functional operation of the device at
these or any other conditions beyond those indicated in the
operational sections of the specifications 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 if you don’t pay
attention to ESD protection. SGMICRO 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.
SGMICRO reserves the right to make any change in circuit
design, specification or other related things if necessary without
notice at any time. Please contact SGMICRO sales office to get
the latest datasheet.
