Overview
The OPA2343EA/2K5G4 is a dual operational amplifier produced by Texas Instruments. It is part of the OPA343 series, which includes single, dual, and quad versions designed for low-cost, miniature applications. These rail-to-rail CMOS operational amplifiers are optimized for low-voltage, single-supply operation and are ideal for various applications requiring high-speed and low power consumption.
The OPA2343EA/2K5G4 operates on a single supply as low as 2.5V and features a wide bandwidth of 5.5MHz and a high slew rate of 6V/μs. It is well-suited for driving sampling Analog-to-Digital (A/D) converters, general-purpose applications, and audio processing.
