Qualification Pedigree(1)
•
(1)
Component qualification in accordance with JEDEC and
industry standards to ensure reliable operation over an
extended temperature range. This includes, but is not limited
to, Highly Accelerated Stress Test (HAST) or biased 85/85,
temperature cycle, autoclave or unbiased HAST,
electromigration, bond intermetallic life, and mold compound
life. Such qualification testing should not be viewed as
justifying use of this component beyond specified
performance and environmental limits.

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
current/voltage 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 2.7 V with an input common-mode voltage range that
extends 500 mV below ground and 500 mV above the positive supply. Output voltage swing is to within 1 mV of
the supply rails with a 100-kΩ load. They offer excellent dynamic response (BW = 5.5 MHz, SR = 6 V/µs), yet
quiescent current is only 750 µA. Dual and quad designs feature completely independent circuitry for lowest
crosstalk and freedom from interaction.
The surface mount package options are SOIC-8 or SOT23-5 for the single (OPA340), SOIC-8 for the dual
(OPA2340), and SOIC-14 surface mount for the quad (OPA4340). All are specified from –55°C to 125°C. A
SPICE macromodel is available for design analysis.
