OPA378AIDBVR Information

General Description

The OPA378AIDBVR and OPA2378 operational amplifiers redefine what is possible in precision and performance. Utilizing a proprietary auto-calibration technique, these devices achieve minimal input offset voltage of 20µV and offset voltage drift of 0.1µV/°C, ensuring unparalleled accuracy. With a high gain bandwidth of 900kHz and low power consumption of 150µA (max), they are tailored for low-power precision applications. Their exceptional PSRR performance, wide input supply range of 2.2V to 5.5V, and rail-to-rail input and output make them an excellent choice for single-supply applications running directly from batteries without regulation. Available in the microSIZE SC70-5 and SOT23-5 packages for the single version (OPA378) or the SOT23-8 package for the dual version (OPA2378), these devices are specified for operation from –40°C to +125°C, making them suitable for various environments and applications
