OPA2227UA Description

The OPA2227UA from Texas Instruments is a high-performance, general-purpose operational amplifier (op-amp) featuring dual-channel architecture in an 8-SOIC package. Designed for precision and stability, it operates over a wide supply voltage range (5V to 36V), making it versatile for industrial, automotive, and instrumentation applications. With an ultra-low input offset voltage of 10 µV and minimal input bias current (2.5 nA), it ensures high accuracy in signal conditioning and sensor interfacing. The 8 MHz gain bandwidth product (GBW) and 2.3V/µs slew rate enable fast signal processing, while its 45 mA output current supports driving moderate loads.
