Texas Instruments Operational Amplifier 8 MHz 8-Pin 18V SOIC OPA2228UA

Texas Instruments OPA2228UA is a precision operational amplifier designed for demanding electronic applications requiring high accuracy and low drift. This dual-channel amplifier features an 8 MHz gain bandwidth product and operates in an 8-pin SOIC package suitable for surface mount technology.

The amplifier supports a wide supply voltage range from 2.5V up to 18V, making it adaptable for various power supply configurations. Its low input offset voltage of ±200 μV and low input bias currents of ±10 nA reduce signal distortion and improve measurement fidelity. With a slew rate of 11 V/μs, it efficiently handles fast-changing signals, suitable for high-speed analog processing.

The device’s operational temperature range from -40°C to 85°C ensures robust performance in industrial and commercial environments. Its compact dimensions (4.9mm x 3.91mm x 1.58mm) allow for efficient PCB space utilization. Since it does not comply with automotive standards, it is mainly suited for laboratory, industrial instrumentation, and general electronic applications.
