SBOS073C –SEPTEMBER 1997–REVISED AUGUST 2016

OPAx340 Single-Supply, Rail-to-Rail Operational Amplifiers

MicroAmplifier™ Series

The OPA340 series operate on a single supply as low

1 Features

as 2.5 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.

These devices offer excellent dynamic response

(BW = 5.5 MHz, SR = 6 V/µs), yet quiescent current

is only 750 A. Dual and quad designs feature

completely independent circuitry for lowest crosstalk

and freedom from interaction.

Rail-to-Rail Output (Within 1 mV)

MicroSize Packages

Wide Bandwidth: 5.5 MHz

High Slew Rate: 6 V/µs

Low THD + Noise: 0.0007% (f = 1 kHz)

Low Quiescent Current: 750 µA/Channel

Single, Dual, and Quad Versions

The single (OPA340) packages are the tiny 5-pin

SOT-23 surface mount, 8-pin SOIC surface mount,

and 8-pin DIP. The dual (OPA2340) comes in the

miniature 8-pin VSSOP surface mount, 8-pin SOIC

surface mount, and 8-pin PDIP packages. The quad

(OPA4340) packages are the space-saving 16-pin

SSOP surface mount and 14-pin SOIC 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.

OPA2340

SOIC (8)

The OPA340 series rail-to-rail CMOS operational

amplifiers are optimized for low-voltage, single-supply

operation. Rail-to-rail input and 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.
