SBOS213C – NOVEMBER 2001 – REVISED MAY 2002  
1MHz, 45µA, CMOS, Rail-to-Rail  
OPERATIONAL AMPLIFIERS  
FEATURES  
DESCRIPTION  
● LOW IQ: 45µA typical  
The OPA348 series amplifiers are single supply, low-power,  
CMOS op amps in micro packaging. Featuring an extended  
bandwidth of 1MHz, and a supply current of 45µA, the  
OPA348 series is useful for low-power applications on single  
supplies of 2.1V to 5.5V.  
● LOW COST  
● RAIL-TO-RAIL INPUT AND OUTPUT  
● SINGLE SUPPLY: +2.1V to +5.5V  
● INPUT BIAS CURRENT: 0.5pA  
Low supply current of 45µA, and an input bias current of  
0.5pA, make the OPA348 series an optimal candidate for  
low-power, high-impedance applications such as smoke de-  
tectors and other sensors.  
● MicroSIZE PACKAGES: SC70-5, SOT23-8 and  
TSSOP-14  
● HIGH SPEED:POWER WITH BANDWIDTH: 1MHz  
The OPA348 is available in the miniature SC70-5,  
SOT23-5 and SO-8 packages. The OPA2348 is available in  
SOT23-8 and SO-8 packages, and the OPA4348 is offered  
in space-saving TSSOP-14 and SO-14 packages. The ex-  
tended temperature range of –40°C to +125°C over all supply  
voltages offers additional design flexibility.  
APPLICATIONS  
● PORTABLE EQUIPMENT  
● BATTERY-POWERED EQUIPMENT  
● SMOKE ALARMS  
● CO DETECTORS
