NOTES: (1) Stresses above these ratings may cause permanent damage. Exposure to absolute maximum conditions for extended periods may de- grade device reliability. (2) Input terminals are diode-clamped to the powersupply rails. Input signals that can swing more than 0.5V beyond the supply rails should be current-limited to 10mA or less. (3) Short-circuit to ground, one amplifier per package.

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 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 100k load. They offer excellent dynamic response (BW = 5.5MHz, SR = 6V/s), yet quiescent current is only 850?A. Dual and quad designs feature completely independent cir- cuitry for lowest crosstalk and freedom from interac- tion.

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 to +85 and operate from -55 to +125. A SPICE macromodel is available.
