Product Summary

The OPA637AU is a Difet operational amplifier. It provides a new level of performance in a precision FET op amp. When compared to the popular OPA111 op amp, the OPA637 has lower noise, lower offset voltage, and much higher speed. It is useful in a broad range of precision and high speed analog circuitry. The OPA637AU is available in plastic DIP, SOIC and metal TO-99 packages. Industrial and military temperature range models are available.
