LOW NOISE: 2.8µVPP (0.1Hz - 10Hz)  
The OPA379 family of micropower, low-voltage  
operational amplifiers is designed for battery-powered  
applications. These amplifiers operate on a supply  
voltage as low as 1.8V (±0.9V). High-performance,  
single-supply operation with rail-to-rail capability  
(10µV max) makes the OPA379 family useful for a  
wide range of applications.  
microPower: 5.5µA (max)  
LOW OFFSET VOLTAGE: 1.5mV (max)

CMRR: 100dB  
PSRR: 2µV/V  
AOL: 120dB  
In addition to microSize packages, the OPA379 family  
of op amps features impressive bandwidth (90kHz),  
low bias current (5pA), and low noise (80nV/√Hz)  
relative to the very low quiescent current (5.5µA  
max).

WIDE SUPPLY VOLTAGE RANGE: 1.8V to 5.5V  
microSize PACKAGES:

SC70-5, SOT23-5, SOT23-8, SO-8, TSSOP-14  
APPLICATIONS  
The OPA379 (single) is available in SC70-5,  
SOT23-5, and SO-8 packages. The OPA2379 (dual)  
comes in SOT23-8 and SO-8 packages. The  
OPA4379 (quad) is offered in a TSSOP-14 package.  
All versions are specified from –40°C to +125°C.
