● 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 circuitry

for lowest crosstalk and freedom from interaction.

DESCRIPTION

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 conver-

sion at the output of Digital-to-Analog (D/A) converters.

Single, dual, and quad versions have identical specifica-

tions for design flexibility.

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 –40°C to +85°C and operate from

–55°C to +125°C. A SPICE macromodel is available for

design analysis.
