FEATURES  
DESCRIPTION  
The SM73302 low noise, CMOS input operational  
amplifier offers a low input voltage noise density of  
5.8 nV/Hz while consuming only 1.15 mA of  
quiescent current. The SM73302 is stable at a gain of  
10 and has a gain bandwidth (GBW) product of 88  
MHz. The SM73302 has a supply voltage range of  
1.8V to 5.5V and can operate from a single supply.  
The SM73302 features a rail-to-rail output stage, and  
is part of the precision amplifier family and is ideal for  
a variety of instrumentation applications.

(Typical 5V Supply, Unless Otherwise Noted)  
Renewable Energy Grade  
Input Offset Voltage ±150 µV (max)  
Input Referred Voltage Noise 5.8 nV/Hz  
Input Bias Current 100 fA  
Gain Bandwidth Product 88 MHz  
Supply Voltage Range 1.8V to 5.5V  
Supply Current 1.15mA  
The SM73302 provides optimal performance in low  
voltage and low noise systems. A CMOS input stage,  
with typical input bias currents in the range of a few  
femtoamperes, and an input common mode voltage  
range, which includes ground, makes the SM73302  
ideal for low power sensor applications where high  
speeds are needed.  
Rail-to-Rail Output Swing  
@ 10 kLoad 25 mV from Rail  
@ 2 kLoad 45 mV from Rail  
2.5V and 5.0V Performance  
Total Harmonic Distortion 0.04% @1 kHz, 600Ω  
Temperature Range 40°C to 125°C  
The SM73302 is manufactured using an advanced  
VIP50 process. The SM73302 is offered in a 5-Pin  
SOT-23 package.
