LOW POWER, SINGLE-SUPPLY, RAIL-TO-RAIL  
OPERATIONAL AMPLIFIERS  
™
MicroAmplifier Series  
FEATURES  
DESCRIPTION  
The OPA344 and OPA345 series rail-to-rail CMOS  
operational amplifiers are designed for precision, low-power,  
miniature applications. The OPA344 is unity gain stable,  
while the OPA345 is optimized for gains greater than or equal  
to five, and has a gain-bandwidth product of 3MHz.  
● RAIL-TO-RAIL INPUT  
● RAIL-TO-RAIL OUTPUT (within 1mV)  
● LOW QUIESCENT CURRENT: 150µA typ  
● MicroSIZE PACKAGES  
SOT23-5  
The OPA344 and OPA345 are optimized to operate on a  
single supply from 2.5V and up to 5.5V with an input  
common-mode voltage range that extends 300mV  
beyond the supplies. Quiescent current is only  
250µA (max).  
MSOP-8  
TSSOP-14  
● GAIN-BANDWIDTH  
OPA344: 1MHz, G ≥ 1  
OPA345: 3MHz, G ≥ 5  
Rail-to-rail input and output make them ideal for driving  
sampling analog-to-digital converters. They are also well suited  
for general purpose and audio applications and providing I/V  
conversion at the output of D/A converters. Single, dual and  
quad versions have identical specs for design flexibility.  
● SLEW RATE  
OPA344: 0.8V/µs  
OPA345: 2V/µs  
A variety of packages are available. All are specified for  
operation from –40ºC to 85ºC. A SPICE macromodel for  
design analysis is available for download from www.ti.com.
