OPERATIONAL AMPLIFIERS  
FEATURES  
DESCRIPTION  
RAIL-TO-RAIL INPUT AND OUTPUT  
The OPA705 series low-cost op amps are optimized for appli-  
cations requiring rail-to-rail input and output swing. Single,  
dual, and quad versions are offered in a variety of packages.  
While the quiescent current is less than 200µA per amplifier,  
the OPA705 still offers excellent dynamic performance  
(1MHz GBW and 0.6V/µs SR) and unity-gain stability.  
WIDE SUPPLY RANGE:  
Single Supply: 4V to 12V  
Dual Supplies: ±2 to ±6  
LOW QUIESCENT CURRENT: 160µA  
LIMITED RANGE CMRR: 96dB  
LOW OFFSET: 0.5mV  
The OPA705 series is fully specified and guaranteed over  
the supply range of ±2V to ±6V. Input swing extends  
300mV beyond the rail and the output swings to within  
40mV of the rail.  
HIGH SPEED: 1MHz, 0.6V/µs  
MicroSIZE PACKAGES:  
SOT23-5, MSOP-8, TSSOP-14  
The single version (OPA705) is available in the MicroSIZE  
SOT23-5 and in the standard SO-8 surface-mount packages.  
The dual version (OPA2705) is available in the MSOP-8,  
SO-8, and DIP-8 packages. The quad OPA4705 is available  
in the TSSOP-14 and SO-14 packages. All are specified for  
operation from –40°C to +85°C.  
LOW INPUT BIAS CURRENT: 1pA
