OPA637AU

Операционный усилитель, одиночный, 80 МГц, 1 Усилитель, 135 В/мкс, ± 4.5В до ± 18В, SOIC.

The OPA637AU is a precision high-speed Difet(R) Operational Amplifier features lower noise and lower offset voltage. The OPA6x7 is useful in a broad range of precision and high speed analog circuitry. The OPA6x7 is fabricated on a high-speed, dielectrically-isolated complementary NPN/PNP process. It operates over a wide range of power supply voltage of ±4.5 to ±18V. Laser-trimmed Difet input circuitry provides high accuracy and low-noise performance comparable with the best bipolar-input operational amplifiers. High frequency complementary transistors allow increased circuit bandwidth, attaining dynamic performance not possible with previous precision FET operational amplifier. The OPA637 is stable in gains equal to or greater than five. Difet fabrication achieves extremely low input bias currents without compromising input voltage noise performance. Low input bias current is maintained over a wide input common-mode voltage range with unique cascade circuitry.
