DESCRIPTION

The OPA341 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 and output and high-speed operation make them ideal for

driving sampling Analog-to-Digital (A/D) converters.

The power-saving shutdown feature makes the OPA341

ideal for portable low-power applications. The OPA341

series is 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 and

dual versions have identical specifications for design flex-

ibility.

The OPA341 series operate on a single supply as low as 2.5V,

and input common-mode voltage range extends 300mV beyond

the supply rails. Output voltage swings to within 1mV of the

supply rails with a 100k

Ω load. The OPA341 series offers

excellent dynamic response (BW = 5.5MHz, SR = 6V/

µs) with

a quiescent current of only 750

µA. The dual design features

completely independent circuitry for lowest crosstalk and free-

dom from interaction.

The single (OPA341) packages are the tiny SOT23-6 surface

mount and SO-8 surface mount. The dual (OPA2341) comes

in the miniature MSOP-10 surface mount. All are specified

from –55

°C to +125°C and operate from –55°C to +150°C.

The OPA343 provides similar performance without shut-

down capability.
