Working Principle

The OPA2237UA/2K5 uses a differential input stage that provides a combination of high-gain bandwidth, low-noise, and low-distortion performance. The input stage provides very low noise and low Total Harmonic Distortion (THD) at full power. It also provides excellent impedance matching for both single-ended and balanced inputs.

The OPA2237UA/2K5 has two outputs, one that is adjustable to provide either single-ended or balanced outputs, and one that is single-ended. This allows the amplifier to be used in both single-ended and differential applications. The combined output power can be adjusted to provide maximum distortion-free output high current levels.

The OPA2237UA/2K5 is specially designed to allow high power applications while still providing low distortion and low noise. The amplifier is rated at up to 2000 mW of output power while providing low distortion performance, with distortion levels as low as 0.003%.

The OPA2237UA/2K5 is designed for maximum power efficiency with low power dissipation. The amplifier is designed for very low power-down current, which allows for low power and low distortion operation. Additionally, it is designed for operation in all audio frequencies, allowing for a wide range of applications.

Conclusion

The OPA2237UA/2K5 is a low noise, low distortion amplifier suitable for many applications, including audio applications, medical and scientific instrumentation, automotive head units, portable sound systems and remote display supplies. It is a single-supply, low-power amplifier that provides high-gain, low-power performances suitable for precision audio applications.
