Overview
The OPA336N/250G4 is part of the OPA336 series of microPower CMOS operational amplifiers designed by Texas Instruments. These amplifiers are optimized for battery-powered applications, offering low power consumption and high performance. They operate on a single supply voltage as low as 2.1V and feature a rail-to-rail output that swings to within 3mV of the supplies with a 100kΩ load. The common-mode range extends to the negative supply, making them ideal for single-supply applications. The OPA336 series includes single, dual, and quad versions, all with identical specifications for maximum design flexibility.
