OPA340 series rail-to-rail CMOS operational amplifi-ers are optimized for low voltage, single supply operation. Rail-to-rail input/output and high speed operation make them ideal for driving sampling analog-to-digital converters. They are also well suited for general pur-pose and audio applications as well as providing I/V conversion at the output of D/A converters. Single,dual, and quad versions have identical specifications for design flexibility. The OPA340 series operates on a single supply as low as2.5V with an input common-mode voltage range that extends 500mV below ground and 500mV above the positive supply. Output voltage swing is to within 1mV of the supply rails with a 100k \Omega load. They offer excel-lent dynamic response (BW = 5.5MHz, SR = 6V/us), yet quiescent current is only 750uA. Dual and quad designs feature completely independent circuitry for lowest crosstalk and freedom from interaction. The single (OPA340) packages are the tiny 5-lead Sot-23-5 surface mount, SO-8 surface mount, and 8-pin DIP. The dual (OPA2340) comes in the minia-ture MSOP-8 surface mount, SO-8 surface mount, and 8-pin DIP packages. The quad (OPA4340) pack-ages are the space-saving SSOP-16 surface mount, SO-14 surface mount, and the 14-pin DIP. All arespecified from -40 oC to +85 oC and operate from -55oC to +125oC. A SPICE macro model is available for design analysis.
