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 Input  
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-kload.  
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.  
Applications  
Driving A/D Converters  
PCMCIA Cards  
Data Acquisition  
Process Control  
Audio Processing

Active Filters  
All are specified from –40°C to 85°C and operate  
from –55°C to 125°C.
