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  
MSOP-8  
TSSOP-14  
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).  
● 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 applicaitons 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  
● THD + NOISE: 0.006%  
A variety of packages are available. All are specified for  
operation from –40ºC to 85ºC. A SPICE macromodel is  
available for design analysis.
