Description

General part information

OPA4343 Series

OPA343 series rail-to-rail CMOS operational amplifiers 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 Analog-to-Digital (A/D) converters. They are also well suited for general-purpose and audio applications as well as providing I/V conversion at the output of Digital-to-Analog (D/A) converters. 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 100kload. They offer excellent dynamic response (BW = 5.5MHz, SR = 6V/us), yet quiescent current is only 850uA. Dual and quad designs feature completely independent circuitry for lowest crosstalk and freedom from interaction.

The single (OPA343) packages are the tiny 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 \x9640°C to +85°C and operate from \x9655°C to +125°C. A SPICE macromodel is available for design analysis.
