Overview
The OPA2244EA-1/2K5 is a dual operational amplifier (op-amp) from Texas Instruments, designed for low power consumption and high performance. This device is part of the OPA2244 series, which includes the OPA244 (single) and OPA4244 (quad) versions. The OPA2244EA-1/2K5 is ideal for battery-powered and portable instrumentation due to its very low quiescent current of 50µA per channel. It is available in an MSOP-8 package, making it suitable for space-limited applications.
