3 Description
The OPA350 series of rail-to-rail CMOS operational
amplifiers are optimized for low voltage, single-supply
operation. Rail-to-rail input and output, low noise (5
nV/√Hz), and high speed operation (38 MHz, 22 V/μs)
make the amplifiers ideal for driving sampling Analog-
to-Digital (A/D) converters. They are also suited for
cell phone PA control loops and video processing
(75-Ω drive capability), as well as audio and general
purpose applications. Single, dual, and quad versions
have identical specifications for maximum design
flexibility.
The OPA350 series operates on a single supply as
low as 2.5 V, with an input common-mode voltage
range that extends 300 mV below ground and 300
mV above the positive supply. Output voltage swing
is to within 10 mV of the supply rails, with a 10-kΩ
load. Dual and quad designs feature completely
independent circuitry for lowest crosstalk and
freedom from interaction.
The single (OPA350) and dual (OPA2350) come in
the miniature MSOP-8 surface mount, SO-8 surface
mount, and DIP-8 packages. The quad (OPA4350)
packages are in the space-saving SSOP-16 surface
mount and SO-14 surface mount. All are specified
from −40°C to 85°C and operate from −55°C to
150°C.
