SGM8591
Single-Supply, Single Rail-to-Rail I/O
Precision Operational Amplifier
GENERAL DESCRIPTION
FEATURES
The SGM8591 is a single, precision operational amplifier
which can operate from 2.5V to 5.5V single supply. The
device provides rail-to-rail input and output operation.
● Low Offset Voltage: 500μV (MAX)
● Ultra-Low Input Bias Current: 15pA
● Large-Signal Voltage Gain: 145dB (TYP) at 5V
● PSRR: 120dB (TYP)
The SGM8591 offers a low offset voltage less than
500μV and an ultra-low bias current of 15pA. The
combination of characteristics makes the SGM8591 a
good choice 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.
● CMRR: 90dB (TYP)
● Overload Recovery Time: 70μs (at VS = 5V)
● Rail-to-Rail Input and Output
● Supply Voltage Range: 2.5V to 5.5V
● Low Supply Current: 445μA at 5V
● No External Capacitors Required
● -40℃ to +85℃ Operating Temperature Range
● Available in Green SOT-23-5 and SOIC-8 Packages
The SGM8591 is available in Green SOIC-8 and
SOT-23-5 packages. It is specified over the extended
industrial temperature range (-40℃ to+85℃).

ESD Susceptibility
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.

Operating Temperature Range .......................-40℃ to +85℃
DISCLAIMER
SG Micro Corp reserves the right to make any change in
circuit design, or specifications without prior notice.
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
may affect reliability. Functional operation of the device at any
conditions beyond those indicated in the Recommended
Operating Conditions section is not implied.
