OPA344NA/250 +BOM

High precision voltage amplifier

OPA344NA/250 General Description

Thanks to its rail-to-rail input and output, the OPA344NA/250 is ideal for driving sampling analog-to-digital converters and is well-suited for general purpose and audio applications. Additionally, it provides I/V conversion at the output of D/A converters. With single, dual, and quad versions all having identical specs, engineers have the flexibility to choose the package that best suits their design needs
