DESCRIPTION
The OPA350 series rail-to-rail CMOS operational
amplifiers are optimized for low voltage, single-supply
operation. Rail-to-rail input/output, low noise (5nV/√Hz),
and high speed operation (38MHz, 22V/µs) make them
ideal for driving sampling Analog-to-Digital (A/D)
converters. They are also well suited for cell phone PA
control loops and video processing (75Ω 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
2.5V with an input common-mode voltage range that
extends 300mV below ground and 300mV above the
positive supply. Output voltage swing is to within 10mV of
the supply rails with a 10kΩ 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
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.
