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 100kΩ load. The OPA341 series offers
excellent dynamic response (BW = 5.5MHz, SR = 6V/µs) with
a quiescent current of only 750µA. 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.
