SGM8555/SGM8556
Single-Supply, Single Rail-to-Rail I/O
Precision Operational Amplifiers
GENERAL DESCRIPTION
FEATURES
The single SGM8555 and dual SGM8556 are precision
operational amplifiers which can operate from 2.5V to
5.5V single supply. These devices provide rail-to-rail
input and output operation.
● Low Offset Voltage: 90μV (MAX)
● Ultra-Low Input Bias Current: 30pA
● Low Noise Density: 21nV/ Hz at 1kHz
√
● Low Voltage Noise: 0.6μVP-P at 0.1Hz to 10Hz
● Gain-Bandwidth Product: 3.5MHz
● Slew Rate: 3V/μs
The SGM8555/6 offer a low offset voltage less than
90μV and an ultra-low bias current of 30pA. The
combination of characteristics makes the SGM8555/6
good choices for temperature measurements, pressure
and position sensors, strain gauge amplifiers and medical
instrumentation, or any other 2.5V to 5.5V applications
requiring precision and long-term stability.
● Voltage Gain: 133dB (TYP) at 5V
● High PSRR: 96dB (TYP)
● High CMRR: 98dB (TYP)
● Overload Recovery Time: 40μs (at VS = 5V)
● Rail-to-Rail Input and Output
● Supply Voltage Range: 2.5V to 5.5V
● Low Supply Current: 950μA/Amplifier (TYP)
● No External Capacitors Required
● -40℃ to +125℃ Operating Temperature Range
● Small Packaging:
The SGM8555 is available in Green SOT-23-5, SOIC-8
and MSOP-8 packages. The SGM8556 is available in
Green SOIC-8 and MSOP-8 packages. They are
specified over the extended industrial temperature
range (-40℃ to+125℃).

Green (RoHS & HSF): SG Micro Corp defines "Green" to mean Pb-Free (RoHS compatible) and free of halogen substances. If
you have additional comments or questions, please contact your SGMICRO representative directly.
ABSOLUTE MAXIMUM RATINGS
may affect reliability. Functional operation of the device at any
conditions beyond those indicated in the Recommended
Operating Conditions section is not implied.

ESD Susceptibility
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.

DISCLAIMER
OVERSTRESS CAUTION
Stresses beyond those listed in Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to
absolute maximum rating conditions for extended periods
SG Micro Corp reserves the right to make any change in
circuit design, or specifications without prior notice.
