OPA4343UA

产品概述

The OPA4343UA is a quad MicroPower™ CMOS Operational Amplifier designed for miniature applications. It is optimized for low-voltage and single-supply operation. Rail-to-rail input/output and high-speed operation makes them ideal for driving sampling analog-to-digital (A/D) converters. It is also well suited for general-purpose applications as well as providing I/V conversion at the output of digital-to-analog (D/A) converters. Quad version has 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 load. It offer excellent dynamic response (BW=5.5MHz, SR=6V/µs), yet quiescent current is only 850µA. Quad design feature completely independent circuitry for lowest crosstalk and freedom from interaction.
