The OPA627 and OPA637 (OPA6x7) operational amplifiers (op amps) provide a new level of performance in a precision FET operational amplifier. When compared to the popular OPA111 op amp, the OPA6x7 have lower noise, lower offset voltage, and higher speed. The OPA6x7 are 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. The OPA6x7 operate over a wide power-supply voltage range of ±4.5V to ±18V. Laser-trimmed input circuitry provides high accuracy and low-noise performance comparable with the best bipolar-input op amps.
High-frequency complementary transistors allow increased circuit bandwidth, attaining dynamic performance not possible with previous precision FET op amps. The OPA627 is unity-gain stable. The OPA637 is stable in gains ≥ 5.
State-of-the-art, precision FET transistors achieve 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 cascode circuitry.
The OPA6x7 are available in SOIC-8 and TO-99 packages. Industrial temperature range models are available.
