Texas Instruments OPAx376/OPAx376-Q1 Low Noise Op Amps

Texas Instruments OPAx376/OPAx376-Q1 Low Noise Operational Amplifiers provide e-trim™, offering outstanding dc precision and ac performance. Each amplifier comes with rail-to-rail input and output, low offset, low noise, quiescent current of 950µA (max.), and a 5.5MHz bandwidth. With these features, it makes them very attractive for a variety of precision and portable applications. In addition, these devices have a reasonably wide supply range with excellent PSRR. This makes these devices attractive for applications that run directly from batteries without regulation. The OPAx376-Q1 devices are AEC-Q100 qualified for automotive applications.
