  • Product introduction

The OPA349 and OPA2349 are ultra-low power 70kHz bandwidth operational amplifiers that provide only 1μA of quiescent current. These rail-to-rail input and output amplifiers are designed for battery-powered applications. The input common-mode voltage range exceeds Rails 350mV within a 200mV range of the rails output, maintaining a wide dynamic range. Unlike some micropower op amps, these components are unity gain stable, require no external compensation, and achieve wide bandwidths. The OPA349 has a low input bias current, making large source and feedback resistors.

Der OPA349 kann mit einer Stromversorgung von 1,8 V bis 5,5 V betrieben werden, ohne dass sich die Leistung ändert, wodurch auch bei niedrigem Batteriestand eine anhaltend überlegene Leistung gewährleistet wird.
