Overview
The OPA2336UA/2K5G4 is a part of the OPA336 series of microPower CMOS operational amplifiers designed by Texas Instruments. These amplifiers are optimized for battery-powered applications and offer single-supply operation with a voltage range from 2.1V to 5.5V. The OPA2336UA/2K5G4 is a quad-channel version, providing four independent operational amplifiers in a single package, which is particularly useful for applications requiring multiple amplification stages.
These amplifiers feature low quiescent current (20µA per amplifier), low offset voltage (125µV max), and high open-loop gain (115dB), making them suitable for a wide range of general-purpose and precision applications.
