The OPA2228U/2K5 from Texas Instruments is a dual operational amplifier designed for high-precision and low-noise applications. It boasts a wide bandwidth of 33 MHz and a typical noise voltage density of 3 nV/√Hz at 1 kHz, making it suitable for demanding audio and instrumentation circuits.
Key electrical characteristics include a low offset voltage of 75 µV maximum and an offset drift of 0.1 µV/°C typical. The amplifier operates over a wide supply voltage range of ±2.5V to ±18V and features a high Common Mode Rejection Ratio (CMRR) of 138 dB and an open-loop gain of 160 dB.
Available in SOIC and PDIP packages, the OPA2228U/2K5 is designed for through-hole or surface-mount assembly. Its architecture is bipolar, contributing to its precise performance characteristics. The operating temperature range is -40°C to 85°C.
This operational amplifier is well-suited for applications requiring high accuracy and minimal noise, such as precision measurement equipment, high-fidelity audio systems, and sensor signal conditioning.
