OPA353 series rail-to-rail CMOS operational amplifi-
ers are designed for low cost, miniature applications.
They are optimized for low voltage, single-supply op-
eration. Rail-to-rail input/output, low noise (5nV/√Hz),
and high speed operation (44MHz, 22V/µs) make them
ideal for driving sampling analog-to-digital 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 design flexibility.
The OPA353 series operates on a single supply as low as
2.5V with an input common-mode voltage range that
extends 300mV beyond the supply rails. Output voltage
swing is to within 10mV of the supply rails with a 10kΩ
load. Dual and quad designs feature completely indepen-
dent circuitry for lowest crosstalk and freedom from
interaction.
The single (OPA353) packages are the tiny 5-lead SOT-
23-5 surface mount and SO-8 surface mount. The dual
(OPA2353) comes in the miniature MSOP-8 surface
mount and SO-8 surface mount. The quad (OPA4353)
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 +125°C.
