Texas Instruments OPA227/OPA228 Operational Amplifier Datasheet
The OPA227 and OPA228 series operational amplifiers combine low noise, wide bandwidth, and high precision. The OPA227 is unity‑gain stable with an 8 MHz gain‑bandwidth product and 2.3 V/µs slew rate, while the OPA228 offers a 33 MHz gain‑bandwidth product and 10 V/µs slew rate for higher‑speed applications.
Both families are available in DIP‑8, SO‑8, DIP‑14 and SO‑14 packages and operate from –40 °C to +85 °C. They replace legacy OP‑27 and OP‑37 devices, providing improved performance for data‑acquisition, telecom, audio, and instrumentation designs.
