SGM8049-1/SGM8049-2/SGM8049-4

1.8V, 2.5µA, 120kHz,

Rail-to-Rail I/O Operational Amplifiers

GENERAL DESCRIPTION

The SGM8049-1, SGM8049-2 and SGM8049-4 micro 

power, low voltage operational amplifiers are designed 

for battery-powered applications. The amplifiers 

operate on a supply voltage as low as 1.8V (±0.9V). 

High-performance, single-supply operation with railto-rail capability makes the SGM8049-1/2/4 useful for a 

wide range of applications.

In addition of small packages, the SGM8049-1/2/4

feature impressive bandwidth, low bias current and low 

noise relative to the very low quiescent current.

The single SGM8049-1 is available in Green SC70-5, 

SOT-23-5 and TDFN-2×2-6L packages. The dual 

SGM8049-2 is available in Green SOT-23-8 and 

SOIC-8 packages. The quad SGM8049-4 is available in 

Green TSSOP-14 package. They are specified over the 

extended -40℃ to +125℃ temperature range.

OVERSTRESS CAUTION

Stresses beyond those listed may cause permanent damage 

to the device. Functional operation of the device at these or 

any otherconditions beyond those indicated in the operational 

section of the specification is not implied.Exposureto absolute 

maximum rating conditions for extended periods may affect 

reliability.

ESD SENSITIVITY 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.
