OPA343 MicroAmplifier(TM) 系列单电源轨至轨运算放大器
OPA343 series rail-to-rail CMOS operational amplifiers are designed for low-cost, miniature applications. They are optimized for low-voltage, single-supply operation. Rail-to-rail input/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.
The OPA343 series operates on a single supply as low as 2.5V, and input common-mode voltage range extends 500mV beyond the supply rails. Output voltage swings to within 1mV of the supply rails with a 100k
