DESCRIPTION
OPA343 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/output and high-speed operation make
them ideal for driving sampling Analog-to-Digital (A/D)
converters. They are also well suited for general-purpose
and audio applications as well as providing I/V conver-
sion at the output of Digital-to-Analog (D/A) converters.
Single, dual, and quad versions have identical specifica-
tions for design flexibility.
The OPA343 series operates on a single supply as low as
2.5V, and input common-mode voltage range extends
500mV beyond the supply rails. Output voltage swings to
within 1mV of the supply rails with a 100kΩ load. They
offer excellent dynamic response (BW = 5.5MHz,
SR = 6V/µs), yet quiescent current is only 850µA. Dual
and quad designs feature completely independent circuitry
for lowest crosstalk and freedom from interaction.
The single (OPA343) packages are the tiny SOT-23-5
surface mount and SO-8 surface mount. The dual
(OPA2343) comes in the miniature MSOP-8 surface
mount and SO-8 surface mount. The quad (OPA4343)
packages are the space-saving SSOP-16 surface mount,
SO-14 surface mount, and TSSOP-14 surface mount. All
are specified from –40°C to +85°C and operate from
–55°C to +125°C. A SPICE macromodel is available for
design analysis.
