DESCRIPTION

ZERØ-CROSSOVER  
The OPA369 and OPA2369 are new low-power,  
low-voltage operational amplifiers from Texas  
Instruments designed especially for battery-powered  
applications.  
LOW POWER: 1μA (max)  
LOW OFFSET VOLTAGE: 750μV (max)  
LOW VOLTAGE SUPPLY: +1.8V to +5.5V  
LOW OFFSET DRIFT: 1.75μV/°C (max)  
microSIZE PACKAGES:  
The OPAx369 operates on a supply voltage as low as  
1.8V and has true rail-to-rail operation that makes it  
useful for  
a wide range of applications. The  
zero-crossover feature resolves the problem of input  
crossover distortion that becomes very prominent in  
low voltage (< 3V), rail-to-rail input applications.  
SC70-5, SOT23-8, MSOP-8  
APPLICATIONS  
BATTERY-POWERED INSTRUMENTS  
PORTABLE DEVICES  
MEDICAL INSTRUMENTS  
TEST EQUIPMENT  
In addition to microsize packages and very low  
quiescent current (1μA, max) the OPAx369 features  
12kHz bandwidth, low offset drift (1.75μV/°C, max),  
and low 0.1Hz to 10Hz noise (3.6μVPP).  
The OPA369 (single version, available Q4 2007) is  
offered in an SC70-5 package. The OPA2369 (dual  
version) comes in both MSOP-8 and SOT23-8  
packages.
