● LOW QUIESCENT CURRENT: 850µA/chan  
● SINGLE, DUAL, AND QUAD  
● TEST EQUIPMENT  
The OPA343 series operates on a single supply as low  
as 2.5V, and input common-mode voltage range extends  
500mV beyond the supply rails. Output voltage swings  
to within 1mV of the supply rails with a 100kΩ load.  
They offer excellent dynamic response (BW = 5.5MHz,  
SR = 6V/µs), yet quiescent current is only 850µA. Dual  
and quad designs feature completely independent cir-  
cuitry for lowest crosstalk and freedom from interac-  
tion.  
DESCRIPTION  
OPA343 series rail-to-rail CMOS operational amplifi-  
ers are designed for low cost, miniature applications.  
They are optimized for low voltage, single supply  
operation. Rail-to-rail input/output and high speed  
operation make them ideal for driving sampling ana-  
log-to-digital converters. They are also well suited for  
general purpose and audio applications as well as  
providing I/V conversion at the output of D/A convert-  
ers. Single, dual, and quad versions have identical  
specifications for design flexibility.  
The single (OPA343) packages are the tiny 5-lead  
SOT-23-5 surface mount and SO-8 surface mount.  
The dual (OPA2343) comes in the miniature MSOP-  
8 surface mount and SO-8 surface mount. The quad  
(OPA4343) packages are the space-saving SSOP-16  
surface mount, SO-14 surface mount, and TSSOP-14  
surface mount. All are specified from –40°C to +85°C  
and operate from –55°C to +125°C. A SPICE  
macromodel is available.
