OPA4340/2340/340

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

UMW

Description

Features

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.

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 OPA340 series operate on a single supply as low

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.
