OPA4350EA/2K5

高速运算放大器 Hi-Spd Single-Sply Rail-to-Rail

Description

The OPA350 series of rail-to-rail CMOS operational amplifiers are optimized for low voltage, single-supply operation. Rail-to-rail input and output, low noise 5 nV/√Hz, and high speed operation 38 MHz, 22 V/μs make the amplifiers ideal for driving sampling Analog to-Digital A/D converters. They are also suited for cell phone PA control loops and video processing 75-Ω drive capability, as well as audio and general purpose applications. Single, dual, and quad versions have identical specifications for maximum design flexibility.

The OPA350 series operates on a single supply as low as 2.5 V, with an input common-mode voltage range that extends 300 mV below ground and 300 mV above the positive supply. Output voltage swing is to within 10 mV of the supply rails, with a 10-kΩ load. Dual and quad designs feature completely independent circuitry for lowest crosstalk and freedom from interaction.
