FEATURES

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 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

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 C to +85 C

and operate from –55 C to +125 C. A SPICE

macromodel is available.
