DESCRIPTION
OPA340 series rail-to-rail CMOS operational
amplifiers 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 conversion at the
output of digital-to-analog (D/A) converters. Single,
dual, and quad versions have identical specifications
for design flexibility.
The OPA340 series operate on a single supply as low
as 2.5V with an input common-mode voltage range
that extends 500mV below ground and 500mV above
the positive supply. Output voltage swing is 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 750µA. Dual and
quad designs feature completely independent
circuitry for lowest crosstalk and freedom from
interaction.
The single (OPA340) packages are the tiny 5-lead
SOT23-5 surface mount, SO-8 surface mount, and
DIP-8. The dual (OPA2340) comes in the miniature
MSOP-8 surface mount, SO-8 surface mount, and
DIP-8 packages. The quad (OPA4340) packages are
the space-saving SSOP-16 surface mount and SO-14
surface mount. All are specified from –40°C to +85C
and operate from –55°C to +125°C. A SPICE
macromodel is available for design analysis.
