3 Description
The OPA340 series rail-to-rail
CMOS operational
amplifiers are optimized for low-
voltage, single-supply operation. Rail-to-rail input and output and highspeed operation make them ideal for driving sampling analog-to-digital (A/D) converters. They are also wellsuited 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.
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
