SINGLE-SUPPLY, RAIL-TO-RAIL
OPERATIONAL AMPLIFIERS
MicroAmplifier™ Series
23
• RAIL-TO-RAIL INPUT
OPA340 series rail-to-rail CMOS operational
amplifiers are optimized for low-voltage, single-supply
• RAIL-TO-RAIL OUTPUT (within 1mV)
operation. Rail-to-rail input/output and high-speed
• MicroSIZE PACKAGES
operation make them ideal for driving sampling
• WIDE BANDWIDTH: 5.5MHz
analog-to-digital (A/D) converters. They are also
• HIGH SLEW RATE: 6V/ µ s well-suited for general purpose and audio
applications as well as providing I/V conversion at the
• LOW THD+NOISE: 0.0007% (f = 1kHz)
output of digital-to-analog (D/A) converters. Single,
• LOW QUIESCENT CURRENT: 750 µ A/channel
dual, and quad versions have identical specifications
• SINGLE, DUAL, AND QUAD VERSIONS
for design flexibility.
The OPA340 series operate on a single supply as low
as 2.5V with an input common-mode voltage range
• DRIVING A/D CONVERTERS
that extends 500mV below ground and 500mV above
• PCMCIA CARDS the positive supply. Output voltage swing is to within
1mV of the supply rails with a 100k Ω load. They offer
• DATA ACQUISITION
excellent dynamic response (BW = 5.5MHz, SR =
• PROCESS CONTROL
6V/ µ s), yet quiescent current is only 750 µ A. Dual and
• AUDIO PROCESSING
quad designs feature completely independent
• COMMUNICATIONS
circuitry for lowest crosstalk and freedom from
interaction.
• ACTIVE FILTERS
• TEST EQUIPMENT
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.
