Working Principle

The OPA2228U/2K5G4 is an operational amplifier that boosts signal quality by operating off a single supply voltage. The op amp’s differential input has an input range from 0 V to a maximum of +16 V. The feedback voltage is adjustable from 0 V to +16 V. The OPA2228U/2K5G4 operates without output current limitation, thanks to its current feedback design. This design allows the output voltage to relatively track the input, leading to minimized distortion or clipping due to current limiting. This is especially beneficial when driving demanding, high-resolution and low-noise applications.

The OPA2228U/2K5G4 has high precision, with a linearity of up to 0.001%. With a low voltage noise of 5 nV/√Hz, it has excellent noise performance, ideal for low-noise applications. The OPA2228U/2K5G4 also features low-offset and low-power consumption and can accept a wide range of input signals ranging from DC to 100 kHz.

The OPA2228U/2K5G4 also features slew-rate control that limits the rate of rise of the output voltage and increases transient response at high frequencies. This feature can be used in combination with a feedback loop to optimize the response of the amplifier over a wide range of frequencies. The OPA2228U/2K5G4 also has a temperature compensated feature, allowing it to remain stable in changes in ambient temperature. This temperature compensated feature is enabled by the temperature compensator which senses temperature changes relative to the supply voltage.

The OPA2228U/2K5G4 is also available in an 8-pin DIP package for easy installation in various applications. The package features a single socket, making it a very convenient solution for prototyping applications. The OPA2228U/2K5G4 also has a wide range of supply voltages, from 2.5 V to 32 V and can be powered from a wide range of single-supply, dual-supply, or battery operated systems. It is also available in both commercial and extended temperature range versions.
