OPA227PA

OPA227PA Description

The OPA227PA from Texas Instruments is a high-precision, general-purpose operational amplifier (op-amp) designed for demanding analog signal conditioning applications. Housed in an 8-pin DIP package, this IC delivers exceptional DC precision with an ultra-low input offset voltage of 10 µV and minimal input bias current of 2.5 nA, making it ideal for high-accuracy systems. Its 8 MHz gain bandwidth product (GBW) and 2.3V/µs slew rate ensure robust performance in both low-frequency and dynamic signal processing tasks. The device operates over a wide supply voltage range (5V to 36V) and consumes 3.7mA of supply current, striking a balance between power efficiency and performance.
