Overview
The OPA2241UAG4, produced by Texas Instruments, is a dual-channel, micro power operational amplifier designed for low-power, single-supply applications. This device is part of the OPAx241 family, which is optimized for operation at low power supply voltages. It is particularly suited for battery-powered, portable devices due to its very low power consumption of 25µA per channel. The OPA2241UAG4 features low offset voltage, rail-to-rail output swing, high common-mode rejection, and high open-loop gain, making it an excellent choice for a variety of applications requiring high performance and low power consumption.
