The OPA343UAG4 is a single-supply, rail-to-rail operational amplifier from Texas Instruments' MicroAmplifier,Ñ¢ series. It operates on a supply voltage range of 2.7V to 5.5V and features a wide bandwidth of 5.5MHz and a high slew rate of 6V/¬µs, making it suitable for high-speed applications. The amplifier exhibits low total harmonic distortion plus noise (THD+N) of 0.0007% at 1kHz, ensuring high fidelity in audio and signal processing applications. The OPA343UAG4 is designed for low quiescent current consumption of 850¬µA per channel, which is advantageous for battery-powered devices. It supports a common-mode voltage range that extends 500mV beyond the supply rails and can output voltage swings to within 1mV of the supply rails with a 100k,Ѷ load. The device is available in compact SOT-23-5 and SO-8 surface mount packages, providing flexibility for space-constrained designs. Operating temperature ranges from -40¬8C to +85¬8C, with a broader operational range of -55¬8C to +125¬8C, making it suitable for various environmental conditions. The OPA343UAG4 is ideal for applications such as driving A/D converters, audio processing, and active filters.
